My GEX levels in Bookmap Cloud Notes

Bookmap Cloud Notes put your own price levels on the heatmap from a CSV file at a web link: each row is a symbol, a price, a note and its colours, with an optional horizontal line. I use them to put my GEX levels where the order book is, so I can see whether there’s a wall sitting at the level.

I publish ES and NQ GEX levels twice a trading day on Scott’s GEX Levels. On a candle chart a level is a line. On Bookmap it’s a line with the order book behind it, which is the difference between knowing where a level is and knowing whether anyone is defending it.

Which plan: notes are part of Bookmap, not a paid add-on (the pricing table lists a notes column on every tier). The levels are free on the site 48 hours after each run; members get the current ones the minute they are computed, into Bookmap and TradingView. Live futures on the heatmap need Global or higher plus a data feed.

$147 for your first quarter or $588 for the first year (then $297 a quarter or $948 a year), 14-day money back on this offer. Prices checked 7 November 2026. All plans and prices. The free tier is a look at the software, not live futures.

What are Bookmap Cloud Notes?

A CSV file Bookmap reads from a link. Each row has the symbol, the price level, the note text, foreground and background colours, text alignment, a diameter (how many price rows the note spans; mine use 1) and whether to draw a horizontal line at the price.

• Comma-separated, with a dot for decimals. Check the file as plain text if a spreadsheet saved it with regional settings.
• The symbol has to match your Bookmap tab exactly, or use an #automap line so one file works across data providers.
• Host it at a direct link: your own server, a raw GitHub file, a Google Drive direct link, or a Google Sheet published as CSV.
• For more than a few dozen lines, gzip the file; Bookmap recognises .gz on its own.

Bookmap’s Cloud Notes guide has the template and the details.

Why put GEX levels on the Bookmap heatmap?

A GEX level says where option hedging is likely to matter. The heatmap says whether anyone has actually parked size there. Put them on the same screen and the call wall stops being a line and becomes a question with an answer: is there a wall at the wall?

A level with heavy resting size on it is one I’ll trade from. A level with nothing on it, or with size that pulls as price arrives, is a line on a chart. That’s the same wall-or-trap read I use at VWAP, applied to someone else’s maths.

How my GEX levels get onto the heatmap

After every GEX run (09:07 and 17:37 ET, Monday to Friday, plus a Sunday refresh) my pipeline writes two Cloud Notes files, one for ES and one for NQ. One row per level: the label with its wall strength as a percentage, centred, a horizontal line at the price.

The pipeline serves both files over HTTPS. I pointed Bookmap at the link once and have not touched it since. Bookmap re-reads the link on its own every five minutes, so the levels on my heatmap change twice a day and I do nothing.

The only chore is the contract roll: the symbol carries the contract code (ESZ6 and NQZ6 right now), so it changes when I roll. Any note I add to the file by hand survives the next rewrite, which is more than I can say for my handwriting.

Here’s the format, as an example. The prices are from the 30 October 2026 Globex run, so take today’s from the levels page, and swap the symbol for the exact one in your Bookmap tab:

Symbol,Price Level,Note,Foreground Color,Background Color,Text Alignment,Diameter,Draw Note Price Horizontal Line
ESZ6.CME@BMD,8131.25,Call Wall 100%,#ffffff,#C92A2A,center,1,TRUE
ESZ6.CME@BMD,7718.75,Zero Gamma,#012463,#F5C242,center,1,TRUE
ESZ6.CME@BMD,7531.25,Put Wall 100%,#ffffff,#2F9E44,center,1,TRUE

Questions people ask

Do Bookmap Cloud Notes cost extra?

No. Notes are part of Bookmap itself, not a paid add-on; the pricing table lists a notes column on every tier. My levels are free on the site 48 hours after each run; members get the current ones the minute they are computed.

Can I put the levels on NQ as well?

Yes. A note is just a symbol and a price, and the levels page has NQ in NQ futures prices as well as ES.

Why not draw the lines by hand?

You can. Fourteen levels, two instruments, twice a day, every trading day. I did the arithmetic and decided I’d rather not.

Where can the CSV file live?

Anywhere that serves a direct link: your own server, a raw GitHub file, a Google Drive direct link, or a Google Sheet published as CSV. Bookmap’s guide notes that Google can block links now and then.
