gamma levels bookmap
You don't have to switch platforms to trade the gamma structure. Mint one API key and my call wall, put wall, gamma flip and the full gamma-by-strike profile draw on your own Bookmap chart — the same levels my terminal draws, recomputed through the session. Included with Pro; today's walls are free to read on the levels page first.
Both screens
The walls are computed once and drawn identically in either place. Keep the terminal open for the read and the same levels on the Bookmap chart you already place orders from, both on one key.
The problem
The dealer-positioning read lives in a browser dashboard and your execution lives in your platform. So you read a number in one window, alt-tab, and eyeball roughly where it lands on the chart you actually trade. The level never touches the thing you press buttons on.
Your Bookmap workspace is years of chart templates, hotkeys and instrument settings. "Just use our terminal instead" is a real cost, and it's the honest reason most traders never try a gamma product at all.
Open interest updates on the exchange's daily cycle, but spot and implied volatility move all session — so the gamma flip genuinely migrates, most visibly on heavy 0DTE days. A level screenshotted at 8am is not the level at 2pm.
What Sharpnel does
A study you install once. The levels render as real chart objects on your Bookmap chart, at your instrument's own prices, next to whatever else you already run.
Call wall, put wall, gamma flip, max pain, the expected-move band, the top gamma strikes, and the full gamma-by-strike profile — the same objects the terminal draws.
The key is included with Pro — no separate purchase — and the same one works across every supported platform, so running two charting setups costs you nothing extra. Want to check the read first? Today’s walls are published free on the levels page and graded against the real session the same day.
| The job | A standalone gamma dashboard | Sharpnel levels in Bookmap |
|---|---|---|
| Where the level lives | In a browser tab, beside the chart you trade | As a chart object on your own Bookmap chart |
| What you do with it | Read a number, switch windows, estimate where it sits | Watch price approach the line on the chart you're already reading |
| What it costs you to adopt | A second subscription and a second window | One study install; your workspace is untouched |

Bookmap is a heatmap, so the walls draw as lines across the liquidity picture you already read — the call wall, the put wall, the flip, max pain, the expected-move band and the top gamma strikes, each one a level you can switch off. Bookmap add-ons cannot carry a status line, so the status is the drawing itself: a level is on screen only while the data is live, and a bottom-panel indicator plots the real age of what you see. This add-on compiles clean against Bookmap's public API and is awaiting its first live test in the platform — if it misbehaves on your chart, write to me and it gets fixed the same day.
Keep your charts. Add the voice.
You do not have to switch. The study draws the walls inside Bookmap, and the Sharpnel terminal runs beside it on a second monitor and talks: it tells you when price reaches a wall, whether the ladder is absorbing there, when you have taken out the London low, when CPI is sixty seconds away. Same key, same walls, your charts. What it said yesterday is on the levels page, in its own voice.
