@Z_R_Ticks Appreciate that a lot man, thank you.
We built GammaTape because we needed it ourselves and we still use it every session — so we’re not about to ditch it. Low early subscriber count doesn’t change that. Glad you see what we’re doing 🙏
fair point — right now Pro/Max replay is about 30 sessions, not years. that’s the product window today (enough to scrub recent RTH behaviour, not a multi-month research archive). we’re looking at extending it; no ETA yet. if you’ve got a specific window you care about (e.g. last 90 days) tell me and I’ll keep that in mind.
same family of math — dealer-style GEX on the 0DTE chain (calls +, puts −), walls = biggest per-side gamma, zero gamma = where net flips. we compute IV/greeks ourselves from mids, plus we have volume-weighted GEX and some smoothing. so you’ll see the same idea as MentorQ / SpotGamma-style tools, but the exact number often won’t match 1:1 (IV source, chain window, OI vs volume weight, etc). if a wall is “the” level on their soft it’ll usually be in the same neighborhood on ours.
