The Foxchase VWAP + Z-Score Bias Engine turns SPY 0DTE volatility and VWAP structure into real-time LONG / SHORT / NEUTRAL bias directly on your chart. It blends price flow (VWAP), extrinsic-value z-score (5-min IV structure), and the Foxchase Regime Framework to automatically detect trend, chop, reversals, and the powerful “IV spike → fade → short” setup seen in major R4 days.

What it does
• Colors candles green/red/gray based on directional bias
• Detects when IV is expanding (trend LONG) vs compressing (trend SHORT)
• Identifies the R4 fade: z-score spikes above +3 then falls to +1.5 → activates early short mode
• Filters chop and prevents bad entries
• Works on SPY 0DTE CALL/PUT charts (1m), using SPY VWAP internally
• Requires zero learning curve — bias label shows everything you need

Perfect for:

0DTE scalpers, VWAP traders, regime traders (R1/R4/R5), or anyone wanting clearer direction in the first 90 minutes.

Includes:
• Thinkorswim study file (TOP STUDY ONLY)
• Free updates up to v2.0

Load it, follow the bias, avoid chop, and trade with the same structure Foxchase uses daily.
