Most order-flow traders rent a gamma-data service, an order-flow platform, a flow scanner, and a charting app — four logins, four bills, and a workflow scattered across windows that don't talk to each other. Sharpnel puts the GEX walls, the DOM ladder, the footprint, the tape, and the chart in one native desktop terminal for $125/month. I built it because I was tired of the alt-tab tax myself.
A dealer-gamma service, an order-flow platform, a flow tool, and a chart subscription. Four logins, four invoices, four update cycles — a $300–500/mo tax on having a real edge thesis, and you still alt-tab between all of them.
Your gamma levels live in one window; the DOM and tape you actually trade off live in another. You read a number, switch windows, and eyeball where it lands. The level never sits on the order flow.
Four separate apps means four things that can lag or crash at the worst moment — a CPI print, an FOMC release. Reassembling the workspace mid-move is how the trade window closes on you.
GEX walls, the DOM ladder, the footprint, the reconstructed tape, and the chart on one workspace. Dealer levels sit on the order flow you're already reading — no alt-tab, no eyeballing.
$125/month for the whole terminal. Real-time, full-depth order-flow analytics on the major futures are included with Pro — you still pay your own broker and exchange market-data fees. The free Explorer tier runs on 15-minute delayed data.
One futures trader builds Sharpnel and trades with it every day — not a VC-backed team shipping an ARR roadmap. When a panel is wrong, I feel it on my own P&L first.
| The job | The typical stack (4 tools) | Sharpnel (1 terminal) |
|---|---|---|
| GEX / dealer-gamma levels | A separate gamma-data subscription, read in its own dashboard or a morning PDF | Call wall, put wall, and gamma flip drawn on the chart, recomputed intraday |
| Depth-of-market ladder | A separate order-flow platform, often a Windows-only Java app | A deep, native DOM ladder with pull/absorption markers |
| Footprint & profile | The same platform or another paid add-on | Multi-mode footprint plus TPO / Market Profile, built in |
| Time & sales / tape | Yet another window to watch | Reconstructed tape with cumulative delta, on the same chart |
| Charting | A separate charting app or subscription | Native charts in the same workspace |
| Monthly cost | ~$300–500/mo across four tools* | $125/mo, one bill (plus your own broker/exchange data fees) |
| Who builds it | VC-backed teams who don't trade for a living | One futures trader who uses it daily |
*Illustrative of a common four-tool setup; your exact tools and costs vary. Sharpnel is software, not a broker — it never sees your broker credentials and never custodies funds, and you pay your own broker/exchange market-data fees.
