Changelog

What changed, and when. The version on your chart badge tells you which release you are on — read upward from there.

Each heading below is a release, and the version in it is the one printed next to the indicator name on your chart. From v1.6 on, OrderVane DOM has its own numbers, and from v1.7 on so do OrderVane Lite and OrderVane Pro — so each heading names the product it covers. Behind a release sits an internal build counter past 1,150 — we cut several builds a day and ship when a change has been proven on our own charts.

How to update: the steps are on Update OrderVane — re-download, replace, restart. When a newer package exists, the indicator name on your chart shows ⬆ Update available.

Pro v1.8 — 7 October 2026

OrderVane Pro. OrderVane Lite has its own v1.7, below; OrderVane DOM stays at v1.6.

• Fixed: on the free version of Quantower, adding OrderVane Pro could make Quantower open a "This function requires a paid license" window, sometimes again and again, and big trades from before the chart opened could be left out. The window no longer opens because of OrderVane, and those earlier big trades are looked up again. We checked this with a connection that does not come with Quantower's paid features (a crypto exchange). If you use Quantower through AMP, nothing changes.

Lite v1.7 — 7 October 2026

OrderVane Lite. OrderVane Pro has its own v1.8, above; OrderVane DOM stays at v1.6.

• Fixed: on the free version of Quantower, adding OrderVane Lite could make Quantower open a "This function requires a paid license" window, sometimes again and again, and big trades from before the chart opened could be left out. The window no longer opens because of OrderVane, and those earlier big trades are looked up again. We checked this with a connection that does not come with Quantower's paid features (a crypto exchange). If you use Quantower through AMP, nothing changes.
• On a newly added OrderVane Lite, at most 6 volume shelves are drawn at once (it was 40). Charts you already have keep their setting. When there are more, the newest in view are kept; to see more, raise Shelf count in the quick menu or Volume shelf max active in Settings.

Pro v1.7 — 29 September 2026

OrderVane Pro only. OrderVane Lite and OrderVane DOM stay at v1.6.

• Pro is much lighter on Quantower, especially in the first minutes after you open a chart. Nothing to change on your side.
• Fixed: right after a chart opened, the previous session's profile and its VAH, VAL and POC lines could be drawn from partly loaded data. They stayed that way until you changed a session-levels setting or pressed Rebuild profile — on one of our charts the lines were more than a dollar from where they belonged. They now correct themselves within seconds as the data finishes loading.
• Fixed: when a chart had no drawings left, the previous session's profile could stay squashed. For example after you deleted your last range-profile box. It now redraws at its normal width.
• On a newly added OrderVane Pro, at most 6 volume shelves are drawn at once (it was 40). Charts you already have keep their setting. When there are more, the newest in view are kept; to see more, raise Shelf count in the quick menu or Volume shelf max active in Settings.
• The Pro guide is corrected in every language. The German, French, Japanese, Portuguese and Chinese guides had sections that no longer matched the product — one said coloured cells stay visible when you zoom out, which the default does not do. The English guide was missing words in the quick-menu section, two of its settings tables printed as plain text in the PDF, and note boxes in the PDFs broke lines in odd places.

Lite & Pro v1.6 — 28 September 2026

OrderVane Lite and OrderVane Pro. OrderVane DOM has its own v1.6, below.

• Fixed: bid/ask wall sizes in Pro were doubled near the price when order-level depth (MBO) was on. A wall line near the market showed twice the size resting there, which also let walls appear there too easily. Wall sizes now show what is actually resting at that price.
• OrderVane Pro no longer writes a diagnostic log to your Documents. With Cover mode set to Full background or Candles only (the default is Hide native (renderer)), earlier versions wrote a short diagnostic record each session to a file in the OrderVane_Diag folder in your Documents. If nothing else you need is in that folder, you can delete it.
• Fixed: the Spanish, Portuguese and French install guides said Windows' "blocked" mark stops the indicator from loading. It does not, and the guides now say so.

DOM v1.6 — 28 September 2026

OrderVane DOM only. Lite and Pro have their own v1.6, above.

• The flow panel has a new heatmap look. Each price row is a solid band coloured by the size resting there — on the dark themes from dark blue for a little, through white and yellow, to red for a lot — and the last-price line takes your buy colour on an uptick and your sell colour on a downtick. It is the default on a newly added DOM; a DOM you already have keeps its old look. Either way you can switch it under Panels & rows ▸ Flow panel ▸ Heatmap style.
• You can tie the heatmap colours to lot sizes. With Fixed colour scale on, the same colour always means the same size: 5 lots or less is the darkest blue and 100 lots or more is red, and the equalizer's FLOOR and TOP set those two sizes. It is off by default, so the colours follow the sizes on screen as before.
• The flow panel can show volume bars. Volume bars (bottom) draws how much traded in each time slice, split into buying and selling. Off by default.
• A trade bubble now shows its buy and sell parts. One bubble, split by side, so you can see what made up the trade. Turn it off under Panels & rows ▸ Flow panel ▸ Marker buy / sell split and each bubble goes back to a single colour, which makes size easier to compare.
• Trades that keep hitting the same price from the same side are drawn as one circle, so a run of trades no longer looks like a string of beads. The newest few seconds stay separate until they are complete. Turn it off under Panels & rows ▸ Flow panel ▸ Group markers.
• Small trade circles are drawn as plain dots, so the price path is easier to follow, and a circle that would blend into a red or orange patch gets a thin outline. The largest size you can set for a circle is now 28 pixels (it was 40).
• You can read the flow panel as numbers. Point at it to see the price, the average resting size there and how long ago. Clock times run along the bottom, and the header shows both ends of the colour scale - for example 3–27 means 3 lots or less is the darkest colour and 27 or more is the top colour. Point at a bubble to see its size split into buys and sells.
• Changing the flow panel's length no longer clears it. Before, switching between lengths wiped the history the panel had collected.
• The flow panel keeps its last 10 minutes across a restart. If you close QT or remove the DOM and open it again within 10 minutes, on the same contract, the panel picks up where it left off. The time it was closed stays shaded, because nothing was recorded then. The panel keeps this in a small file per contract in the OrderVane_DOM folder in your Documents.
• Fixed: a new contract month could show the old month's flow history. Switching to another month now starts the flow panel fresh.
• The flow panel's help text now matches what it does. The Heatmap style and panel width tooltips describe the current drawing and limits, the note on the panel's header describes the look and the lines you have switched on, and the Brightness scale item is only shown in the blocks style, where it applies.
• Fixed: typing auto in the equalizer's SCALE box did nothing. Our guide said it was accepted, but the box ignored it. It now switches the circle scale back to automatic; typing 0 still does the same.
• Fixed: the equalizer did not open while the flow panel had no data. With the market closed, or in the first seconds after the DOM attached, pressing EQ lit the button and nothing appeared. It now opens at any time; the sliders change the settings, and the panel shows the result once depth arrives.
• The DOM window and your chart share one crosshair. Point at a row in the DOM and the chart marks the same price, and the other way round; the DOM also draws its own crosshair across the flow panel and the ladder. This is on by default; turn it off under Panels & rows ▸ Lines ▸ Chart crosshair link.
• The shared crosshair takes the DOM theme's accent colour, in the DOM window and on your chart, so it changes when you change the theme. If that colour would not show on your chart, it falls back to the chart's text colour.
• You can drag the edges to set widths. The edge of the tape panel, the edge of the flow panel, and the edge of any column can all be dragged — the pointer turns into ↔ when you are on one. Column edges now work all the way down the ladder, not only on the header row.
• One item puts the layout back. The column menu ends with Reset layout, which returns column widths, column order and both panel widths to their designed values. It replaces the separate reset items that were there before.
• Column presets now cover every column. Before, Full left four columns untouched (#Chg, My orders queue est., Fill chunks, P&L) and Minimal left them on. Full now turns every column on, and Minimal turns every optional column off, leaving price, bid, ask and the add/pull columns.
• Some items were renamed. The column presets are now Columns: Minimal, Columns: Full and Columns: Order flow (the last one was called Bookmap-style). In the in-chart DOM's quick panel, Volume at price is now Session volume and Queue boxes (window) is now Order queue boxes. They work as before — only the names changed.
• The toolbar shows the last price. In a wide window the middle of the toolbar shows the last traded price and its change since the previous settlement, in price and in percent together - for example −0.74 (−0.80%). The Change field in the strip below appears only when the toolbar has no room for it.
• In a narrow window the toolbar folds instead of overlapping. The less-used buttons are tucked away first; the menu and column buttons always stay. Column captions switch to short names when a column is narrow.
• Numbers no longer run into each other in a narrow DOM window. A volume figure could touch the price next to it and read as one number. Figures now keep a gap, a chip that does not fit is left out, and the warning at the top shortens instead of being cut off.
• Numbers read the same way everywhere. The info strip and the totals along the bottom show full numbers such as 12,345 instead of 12.3K; the ladder keeps short numbers, and pointing at a cell shows the full one. Negative numbers use one minus sign throughout, column names have a little more room between them, and #Ord, #Chg and ± leave out a number that does not fit.
• The first info field is now called Depth. It shows when this window started receiving market depth. It used to be labelled Session.
• Confirmations appear next to the mouse. Short notices such as "layout reset" now show beside the pointer for a few seconds, where you are looking.
• The ladder is easier to read. Size bars are lighter so the numbers stand out, column borders are clearer, the best bid and ask lines are thinner, and the price column is drawn as a filled strip. In the Sess column only the session's point of control stays amber.
• The DOM menu and the input boxes follow the theme. Picking a theme under Theme in the DOM menu recoloured the window but left the open menu in the old colours until you opened it again, and the equalizer's number box and the note box were always white. Now they take the theme's colours together with the window.
• The Light theme is easier to read. Numbers coloured by direction, and the last price, now stand out from their background.
• The VPS bar now shows both sides. The sold part is on the left in your sell colour and the bought part on the right in your buy colour; the number is still the total.
• Fixed: VPB, VPA and VPD showed the wrong values. VPB and VPA were swapped, and VPD showed the opposite sign — a price where sellers traded more showed a green plus. They now match their descriptions: VPB is volume traded at the bid, VPA at the ask, and VPD is ask minus bid. These three columns are off unless you turned them on.
• Fixed: Imb showed 100% when one side was empty. When nothing rested at the matching price on the other side - or that price was deeper than your data feed sends - the row read 100% in the side colour and looked like a strong imbalance. Those rows are now left blank.
• Fixed: bid/ask wall sizes near the price were doubled when order-level depth (MBO) was on. A wall line near the market showed twice the size resting there, which also let walls appear there too easily. Wall sizes now match the ladder.
• Fixed: three column descriptions did not match their columns. The tooltip on Lvl described a different column; it now explains the key-level tags. The tooltips on the recent volume column and on Flow now say where their numbers come from.
• Point at any number to read what it means. Rest the mouse on a cell for a moment and a note explains it for that price: what the number counts, since when, and how to read it - for example how much traded against a resting level, or how the volume there splits between buyers and sellers. The totals along the bottom are explained the same way. Turn it off in the DOM menu under Explain cells on hover.
• The ladder holds still while you point at it. Moving the mouse over the ladder or the flow panel pauses auto centering, so the price under the mouse does not change; it catches up two seconds after the mouse stops (or once you move on from a cell note you are reading), and the notice line says when it is waiting. Turn it off with Pause centering while pointing in the DOM menu.
• You can mark important prices. Right-click a price row in the DOM window and choose Mark, or point at the row and press M. The mark is an ordinary horizontal line across the whole width of your chart, and the DOM shows it as a border on the price with a light band across the row, in the line's own colour. Horizontal lines you draw on the chart yourself show in the DOM the same way, and there is no switch to hide them. New marks are violet (teal in the Purple theme), so they do not look like the last-traded row. To move, recolour or delete a mark, edit the line on the chart, or right-click the row and choose Unmark. A new mark is not left selected on the chart, so pressing Delete there will not remove it by accident. When you drag a line on the chart, its mark follows at once.
• Keys work where you point. While you move the mouse over the DOM window, M marks or unmarks the row under it and R or Space recenters - you no longer need to click the window first. Two seconds after the mouse stops, those keys go back to your other programs.
• On the in-chart DOM, the fill label no longer sits on top of the price. It now sits at the outer edge of the bid or ask column, as it does in the DOM window.
• The in-chart DOM no longer hides under another OrderVane indicator's bar statistics when that strip is at the top of the chart; the ladder now starts below it.
• OrderVane DOM no longer creates an Indicator18_PyS2_Signals folder in your Documents. If you use only OrderVane DOM and have that folder, you can delete it.

v1.5 — 22 September 2026

• New charts remember your licence key. Before, every newly added OrderVane indicator started with an empty key box and you had to paste the key again. Now, once your key is activated on this PC, a new chart fills it in for you.
• Lite and Pro on the same PC no longer use up activations. Before, running both made each one re-activate on every start.
• If OrderVane fails while starting on your chart, it now shows you why. Before, it could stay silent: Quantower drops an indicator that fails while starting. The chart now carries one line with the reason and your Quantower version — enough to fix it yourself, or to send to us. If OrderVane does not appear in the indicator list at all, it is not in the right folder — see the install guide.
• The install steps are clearer about the folder. The indicator must sit at Settings\Scripts\Indicators\OrderVane_<tier>\ — one folder, with the .dll directly inside.

v1.4 — 21 September 2026

• The chart no longer stops for about a second every minute. It happened while OrderVane was writing its cache to disk; drawing now never waits on that file.
• Clicks and settings changes redraw the chart instead of recalculating it. Panning, zooming and toggling options are quicker, and the pauses that built up during a long session are gone.
• Quantower's own volume analysis reads the real volume again. On charts running OrderVane it could still show two or three times the true figure. The cause was ours and is removed at the source, so the numbers in Quantower's panels are correct from the moment you load the new build.
• Nothing is drawn over Quantower's price axis. Levels, bands and profile lines now stop at the edge of the chart.
• Nothing is drawn over the statistics strips. Markers, profile lines - including the automatic previous session VWAP - and every other overlay stop at the bottom edge of the chart pane instead of crossing Quantower's statistics panel, the time axis, or our own bar statistics strip.
• Changed (all tiers): bar statistics row labels sit in the price axis by default, the way Quantower labels its own rows. To put them back on the chart, use Bar stats: row labels in the settings window.
• A stray Suite ? label no longer appears above the chart. It showed on every released build since obfuscation was introduced, and never on the builds we test with, which is why it lasted. Nothing else about it was real - it was a diagnostic string, not a licence state.
• Hover help on the on-chart panels. Every button in the quick panels shows what it does, and 33 settings that had no description now have one.
• The trial notice on the chart links straight to checkout, so an expiring trial no longer needs you to find the page yourself.

OrderVane DOM

• New: cost to take. Enter the size you are about to trade in DOM cost to take (lots, 0=off) and the ladder header shows what that size costs right now, in ticks, on each side. It is a calculation from the book in front of you, not a forecast. A > in front of the number means the visible book cannot fill that size - that is when it is most expensive. Off by default.
• Dark is really dark, and there are two more themes (purple and ember). Cycle them from the window menu.
• The window menu is ordered by what you reach for most, and every cell, button and column header explains itself on hover.
• Notes open from the menu. Notes > Open notes folder opens the CSV that your price notes have always been saved to.
• The support log stays off unless you turn it on. DOM diagnostic log (support only) writes nothing - and creates no folder - until you enable it, stops growing past 4 MB, and can be deleted at any time. Turn it off again when support is done with it.

v1.3 — 14 September 2026

• Removed (Pro): the tape speed box and the vertical tape meter, with their eight settings: Tape speed gauge, Tape gauge size, Tape gauge window (sec), Tape impact sample (trades), Tape verdict floor (%, 0=off), Tape meter (vertical column), Tape meter width (px) and Tape meter sessions (1-5). Tape speed itself stays: the tape speed row in bar statistics, Tape hot alert, and the speed bars in range profiles.
• The settings window opens complete. It could sometimes open with only the View section.
• Trial reminders show the current price. They were still quoting the price from before the September price change.
• Renko charts no longer reload their markers over and over. It also stops cache files from piling up on disk and the delta unavailable notice in bar statistics from staying up.
• Volume analysis no longer over-counts. On charts running OrderVane, Quantower's own volume analysis could still read two or three times the real volume in some cases. The cause was ours.
• Range profile boxes that reach past the newest bar hold their right edge instead of creeping further right over time.
• Range profile speed bars start off, and were switched off once on charts where they were on. To bring them back, turn on Range profile: tape histogram.
• Buttons and labels no longer overlap — the quick buttons in a short chart window, and the top labels when more than one OrderVane tier is on the same chart.
• Smaller stability fixes.

v1.2 — 1 September 2026

• Bar statistics now match the platform's own volume figures. In v1.1 the Vol and delta rows in the bar statistics grid could read exactly double what Quantower's own volume analysis showed for the same bar. The cause was ours: we were asking the platform to recalculate volume analysis it had already produced, and both results accumulated in the same store. We now check whether the data is already there rather than waiting on a state this data feed never reaches. If you compared our numbers against the platform's and they disagreed, that is why.
• Footprint delta column — the horizontal delta bars can now be scaled against the whole chart instead of each bar's own maximum, so a large delta reads as large. Delta numbers also sit further from the next bar's edge, and the column can be widened from the on-chart panel.
• Cells step aside when they cannot be read — at zoom levels where the bid/ask numbers no longer fit, the cells hide instead of drawing an unreadable block, leaving the candle and the right-hand profile visible.
• Quick panel — delta column width and statistics row height adjust in single steps, with hold-to-repeat for larger moves.
• Volume shelves — labels now state the window each shelf was measured over, and the shelf line is coloured by the side that traded more at that price. Shelves are measured on a fixed window rather than the chart's timeframe, so the same price reads the same on any timeframe.
• The tape meter stays where it is put. On Renko, range and tick charts the vertical meter could slide left and right as time passed. Its position was anchored partly to a time value that keeps moving while the newest bar is still forming, and on those chart types that value is extrapolated once it passes the last bar. It now anchors to the bar's geometry, which does not move.
• Range profile and the session levels received a long run of accuracy and readability work.

v1.1 — 27 August 2026

• Stacked absorption zones — two or more same-side absorption bars on adjacent prices merge into a zone (Abs▲ ×N), projected right until a closed bar trades through its far side.
• Symbol presets — one-shot starting thresholds for ES, NQ, GC and RTY / 6E, scaled from the CL defaults by published daily volume. Pick one in the quick menu and the three volume steppers under it change immediately; touch any of them and the row reads Custom. Starting points, not measured optima — the chart is still where you tune them.
• Tooltips came back in the settings window — on Lite, every setting description was being swallowed by an error handler it shared with something else, so hovering showed nothing at all. Each setting explains itself again.
• A diagnostic block was writing to your disk — an internal Level 2 dump shipped enabled and wrote to your Documents folder, past 8 MB on one machine. It is gone.
• An internal identifier was editable in the settings window — the range-profile origin key was supposed to be hidden and was not. It is hidden again.
• Finding an update — the chart badge now says where to go (⬆ Update available · ordervane.com/update). That page carries the whole procedure in seven languages: where to re-download, what to do if you lost your key, how to move to another computer. Your install guide says the same, so you never need the site to update.

v1.0 — August 2026

• License hardening — a brief network drop during validation could silently consume one of your two activation slots. Validation now waits the drop out instead. If this ever caught you, write to us and we free the slot.
• Diagonal imbalance: true price adjacency — on sparse ladders the diagonal comparison could pair rows several ticks apart. It now verifies the two rows are genuinely adjacent — the behavior the guide had always described.
• Documentation site — concept and reference pages for reading order flow, in seven languages, at /docs/.
• Volume shelves — a price that took an unusual share of the volume around it, measured against three windows at once and identical on every timeframe. In every tier, on by default.
• Two kinds of bubble — a single large print and a one-price accumulation used to look identical. Accumulations are now drawn dashed with a ∑ prefix, and derived markers (clusters, absorption) use real prints only.
• Pro released — the footprint suite: cells, vertical and diagonal imbalances, candle takeover, stacked imbalance zones and style presets, with its own guide in 7 languages.
• Lite released — big-trade bubbles, aggression clusters, absorption bars and the on-chart quick menu, with an install guide in 8 languages.

Before the changelog

OrderVane went on sale in August 2026. The roughly seven hundred internal builds before launch are where the detection engines, the disk caches and the honest loading behavior come from. This page starts where customers start.
