Most SPX 0DTE Traders Focus on Direction — I Focus on Where Price Is Unlikely to Go

A lot of 0DTE traders spend most of the day trying to guess whether SPX is going up or down.

I don’t really trade that way anymore.

What I care about more is: **where is price unlikely to go today?**

That’s where GEX helps me.

If I see a strong gamma resistance level above price and SPX keeps rejecting it, I may sell a Bear Call Spread above that area.

Same thing on the downside. If there’s strong support and price keeps holding it, I may look for a Bull Put Spread below it.

I don’t need to predict the exact close.

I just need SPX to stay away from my short strike.

For me, that’s a much simpler way to trade 0DTE.

GEX isn’t magic and levels can break, so I still look at trend, structure, volatility and time remaining. But it gives me a framework for deciding where I actually want to take risk.

Curious how others here choose their 0DTE strikes. Delta? Technical levels? GEX? A mix?
