How I screen what's actually safe to hold overnight using dealer gamma — flip below, wall above, ranked by R:R The overnight hold question isn't about news, it's about where you sit vs dealer hedging. Below the zero-gamma flip dealers amplify moves. Above the flip with room to the call wall, they dampen everything. I bracket each name: distance down to the flip vs distance up to the wall, then rank by that ratio. Anything with earnings inside 48h gets tossed. https://preview.redd.it/j8i55sidxeoh1.png?width=1810&format=png&auto=webp&s=a55320e4152a5c38a5f7d2fdc6ff251ff35d1e38 # Snapshot from tonight: **Good bracket:** LRCX has 2.45% up to the wall and only 0.83% down to the flip — basically 3:1. CRWV \~2:1, HOOD 1.7:1. **Same zone, garbage trade:** *AVGO is in zone* just like LRCX... with 0.67% left to the wall and 5% down to the flip. 0.13 R:R. Identical badge, opposite trade. This is why the zone label alone will lie to you. **Past the wall:** SMCI, INTC, AMD, COIN, META, MU — already blew through the level. Air pocket, no dampening left. **Below the flip:** MSTR and NVDA right now. And honestly when the majors are down there, your individual name's cushion doesn't matter much — size down regardless. Disclosure: this is off a paid tool on a site I work on, but the framework is the point — flip/wall bracket + R:R instead of a binary zone check. You can do it by hand off any free GEX chart if you don't mind the math per name.
