The OI tool that publishes its own failures.
Daily OI structure scanner. PIN measured AUC 0.83 in our 30,000-trade backtest. We publish where it doesn't work too — including SQUEEZE's p=0.9562 vs random. That's the transparency competitors won't do.

Is $19.99/mo worth it?
At $19.99/mo, this is one Robinhood lunch. The value is in the data, the transparency, and the OI tooling — not the promise of profits we can't verify. PIN has a measured AUC of 0.83 across 30,000 historical trades. That's a real signal. SQUEEZE is a structural pattern finder — useful for identifying setups, not a guarantee. We publish the backtest results openly, including where scoring fails. If you want a tool that lies to you, this isn't it.

Common Questions
How does OptionWalls work?
We ingest end-of-day options open interest for 100+ tickers each night. SQUEEZE, PIN, and CAGE setups are scored 0–100 based on wall structure, IV compression, and OI velocity. Every setup comes with a clear idea on which stock to pick.
What is a gamma squeeze?
When a tight call wall above spot meets compressed IV and accelerating call OI, dealers get squeezed. They're short gamma — forced to buy the underlying as price rises, which pushes it higher. That's the cascade. We score the setup before it triggers.
What's the actual win rate?
PIN: AUC 0.83 (measured) in our 30k-row backtest — our strongest signal. SQUEEZE: no statistically significant edge vs random at default weights (structural candidate finder). CAGE: AUC 0.55 (measured) — useful as a structural reference, not recommended as a standalone trade. Full receipts at /backtest. Past performance is not indicative of future results.
