The 99th Floor Indicator

Strike selection
driven by math,
not instinct.

Built in Pine Script v6 for TradingView, the 99th Floor indicator suite calculates percentile-based strike levels from actual historical open-to-low price ranges — not theoretical models. Every strike you see has been statistically tested against years of price history.

A dual-engine design combines the historical percentile engine with live IV analytics.

How it works

Three pillars of the
99th Floor system.

I
Statistical Strike Selection
Percentile levels are derived from actual price history — where SPY and QQQ have and haven't gone on a weekly and daily basis. The 99th percentile strike is your actual trade strike. No guessing.
II
Rules-Based Entry Grading
Eight scored signals for 5DTE trades, seven for 0DTE. IV regime, trend filter, expected move confluence, distance metrics — combined into a single letter grade that tells you the quality of the trade before entry.
III
Binary Trade Management
Hold to expiration for full credit, or exit at −300% to cap the loss. Taking profit early is always on the table if your risk comfort calls for it — the framework gives you the edge, you decide how to manage it.
