FlashAlpha alternative — if you wanted a desk and a grade, not a raw GEX API
FlashAlpha is a developer analytics API: REST + MCP for gamma/delta/vanna/charm exposure, walls, flip, 0DTE stats, and (on higher tiers) historical replay across thousands of names. Signal Technology is not that company. We are a live 0DTE desk (SPY/QQQ/IWM rails) + graded Discord for SPY. If you need programmable greeks and a lab feed, keep FlashAlpha. If you need a same-day confirmation grade with invalidation, that is us.
Plain-English rails: SPY gamma walls · gamma flip · our MCP (desk-scoped, not a FlashAlpha clone).
Who each is for
FlashAlpha fits quants, agents, and builders who want GEX/DEX/VEX/CHEX and 0DTE analytics in JSON — any ticker they query — and will write their own dashboard, bot, or research notebook on top.
Signal Technology fits traders who want live walls/flip on a web desk, a scanner that stays quiet below 6/8, and graded alerts at $99/mo (Signal) and the live desk at $199.99/mo (Desk). We compute our own map. We do not resell FlashAlpha. Ourexposes this desk, not a general-purpose exposure lab.
| Job | FlashAlpha | Signal Technology |
|---|---|---|
| Programmable GEX / DEX / VEX / CHEX | Core (REST + MCP, 6,000+ names) | Desk Exposure board — not a drop-in lab API |
| Live gamma rails / flip on a trader UI | You build the UI | Decision Desk is the product |
| Graded A+/B 0DTE alerts | Not their model | Discord + Pro strip, 6/8 floor |
| Historical minute replay | Alpha-tier lab | Session replay / public stats — not FA-style history |
| Ticker focus | Any symbol the API covers | Discord + SMS: SPY/QQQ/IWM/SMH/GLD · Desk: same five · Tape: SPY |
| Starting price (typical public) | API tiers from a free key up through Growth/Alpha | Signal $99 · Desk $199.99 · All-Access $299 |

No fabricated win rates. If your bottleneck is “I need GEX in JSON for my own stack,” we are not a substitute. If your bottleneck is “I have levels and still chase,” the grade is the product. More maps: Quant Data, SpotGamma, Unusual Whales.
