What FlashAlpha offers
Read dealer gamma to know when moves run versus mean-revert, and pair it with implied/realized vol so you only pay up for options when the volatility is actually on your side.

Frequently Asked Questions
Everything you need to know before using the API.
Q
How does dealer gamma affect a directional move?
In negative gamma (spot below the flip) dealers hedge with the move, amplifying it, good for momentum. In positive gamma they hedge against it, dampening moves toward a pin, better for fading.
Q
Should I buy options in long or short gamma regimes?
Momentum and trend-following generally fare better when dealers are short gamma (below the flip); range/pin conditions favor premium selling instead. The endpoints tell you which regime you're in.
Q
Which plan do I need?
Single-expiry GEX is Free; flow-GEX (live dealer gamma) and the volatility endpoint are Growth.
Q
Which symbols are supported?
Any US equity or ETF with listed options; index symbols need Basic or higher.

Time entries with the dealer path and the vol backdrop together: live flow-GEX, key levels and the full volatility context in one tier.
- Flow-GEX and key levels - time entries when the dealer path is open
- Full volatility context - the IV-RV spread so you never buy direction and rich vol together
- ES / NQ futures included - index bias before the cash open
- AI narrative - the regime read in plain English
When Alpha instead: directional VRP and structure scoring pick the expression with measured edge, and historical replay lets you validate the timing signal before risking it.
