Know which way
the tide is turning.
Every options trade forces a dealer to hedge, and all those trades pull on price like a hidden tide. TIDAL maps that pull — the levels influencing price, from dead zones where it stalls, to the surge zones where it breaks loose.
Price is just the surface.
TIDAL reveals the depths of dealer positioning.
The chart shows you only the surface price action. But underneath runs currents you can't see: every options contract a dealer holds forces them to buy or sell the underlying to stay hedged, and that hedging makes price ebb and flow throughout the day.
When dealers are long gamma, that current runs against the move — it pulls price back. When they're short gamma, the current runs with the move — a rip that carries price away. Tidal reads that current and charts where it pulls hardest, where it stalls, and where it can turn.
Dead Zones
Where dealers are long gamma. They hedge against the move, soaking up volatility. Price pins and reverts here — the levels that hold.
Surge Zones
Where dealers are short gamma. They hedge with the move, feeding volatility. Levels here give way and price runs — the accelerants.
Turn of the Tide (Gamma Flip)
The price where total dealer gamma crosses zero. Above it, chop and reversion; below it, trend and breaks. The single most useful line on the chart.
Every strike, every expiry, at once.
The gamma profile is one slice in time. The matrix is the whole board: each cell is the dealer dollar-exposure at one strike for one expiry, shaded by how strongly hedging pulls there. The Anchor marks the single heaviest level — the one price gravitates toward. Scan down a column to read one expiry; scan across a row to see how a strike's pull builds or fades over weeks. Filter strikes and expiries to zoom from the whole board down to today's 0DTE.
Don't guess. Measure.
Most gamma maps assume dealers are long every call and short every put. Tidal reads trade-level flow and classifies each print by aggressor side, so the map reflects the side dealers are actually on — not a textbook assumption. The result is a cleaner picture of where hedging will actually flow.
