FirmTape

SPX dealer-positioning terminal. Three products: (1) LIVE streams net dealer gamma by strike, the zero-gamma flip, call and put walls, vanna and charm every second the market trades; (2) REPLAY opens every finished session free, 1,000+ trading days back to the first daily SPX expiries, no account; (3) LAB compiles a trading idea written in plain words into a rule, backtests it over the whole archive with out-of-sample verdicts, quant-optimizes it and draws the survivors on the LIVE chart. An MCP server (mcp.firmtape.com) gives AI assistants REPLAY for free and, with a Lab token, LAB.
