How GEX Filter works
Under every chart is a current you can't see: the hedging of the dealers on the other side of the options market. Above one line they lean against moves and the market chops. Below it they push moves bigger and trends run. The GEX Filter builds that map from the real option chain and turns it into one verdict. Check the current before you paddle out.
Builds the gamma map itself
From the live option chain: open interest and implied volatility at every strike across every expiration. No outside data feed and no guesses.
Finds the key lines
The flip line (HVL), the ceiling (Call Resistance), the floor (Put Support) and the magnet price the market tends to drift toward.
Gives you a verdict
🟢 GO for full size, 🟡 GO WITH CARE for half size, a pin, or price action alone, and 🦈 SHARK SIGHTING (Sit Out) when momentum and breakout trades should wait.
Reads the price of insurance
Whether options are cheap or rich against the past year, combined with whether the water is calm or jumpy.
Calm on the board, whatever the ocean does.
It's the filter for every other tool.
Run it beside the Scalper, Session Coach or Trend Rider Swing and it tells you which of their signals to trust today.
Gamma in plain words.
HVL, walls and the magnet come with a verdict a beginner can act on.
Honest about timing.
Open interest updates once a day, so it's a daily map, not a tick-by-tick feed.
