KERYKEION M.E.X.

Live

Raw GEX (dealer gamma exposure) is spread across every strike and is noisy. M.E.X. distills it into the few walls and key levels that matter for the session at hand. For NQ, ES and GC futures and the SPX and NDX indices. Runs as an indicator inside the trader’s own trading platform.

Data, not trading signals. Every session, published as recorded.

Real MDD

Live

Trading platforms compute max drawdown from the closed-trade balance, a staircase that shows nothing while a trade is open. Real MDD rebuilds the path between the steps from the trader’s own trade log and price data, entirely in the browser.

Measures the past path. Does not predict or advise.
