Best 0DTE Trading Strategies (Structured, Not Random)

"Best 0DTE strategy" posts usually list generic tips. The honest answer is simpler: the best strategy depends on dealer gamma that day. Positive GEX favors premium selling and fades; negative GEX favors directional momentum and tight risk. Here are the four strategies that survive when you match them to the regime — not the other way around.

Strategy 1: Wall fade (positive GEX, above the flip)

When GEX is positive and spot is above the gamma flip, dealers dampen moves. Fading toward the call wall (short calls or call spreads) or buying dips toward the put wall fits the mechanical flow. Works best mid-morning after the open volatility settles.

Fails when: GEX flips negative intraday or a headline breaks the range — have a hard stop.

Strategy 2: Momentum continuation (negative GEX, below the flip)

Below the flip in negative gamma, hedging accelerates moves. Directional 0DTE calls or puts (or debit spreads) with the trend align with dealer flow. Confirm with options flow — ask-side aggression on the same side as the move.

Fails when: You chase after the move is extended; gamma cuts both ways on reversals.

Strategy 3: Iron condor (positive GEX, tight range)

When walls bracket price and IV is elevated, iron condors harvest theta with defined risk. Place shorts just outside the walls, not at round numbers. See SPX condor geometry for how positioning informs strike selection.

Fails when: Negative GEX or macro events — skip or cut size in half.

Strategy 4: Scalp the open (high gamma, first 30 minutes)

The first 30 minutes of 0DTE carry peak gamma. Traders with a clear opening positioning read take one structured shot — then stop. Revenge trading 0DTE is how accounts die; see Is 0DTE Gambling? for the discipline checklist.

What not to do

- Buy lottery OTM calls with no regime read. - Hold short premium into negative GEX without a hedge. - Size SPX like SPY — one point is ~$100 on SPX options notional.
