SPX SPY 5Min Lock
🔹 DESCRIPTION (Public Library)
This indicator overlays SPX price levels directly onto the SPY chart by converting SPX levels into SPY prices using a session-locked SPY/SPX ratio.
Instead of mentally translating SPX levels, you see them mapped precisely on SPY, where you actually trade.
How it works
• Calculates the SPY-to-SPX price ratio
• Locks the ratio at the first 5-minute RTH candle close (9:35am ET)
• Uses that fixed ratio for the entire session
• Converts SPX levels into accurate SPY-equivalent prices
• Draws clean labels (and optional short stubs) directly on SPY
Why the 5-minute lock
SPY and SPX can drift slightly during the day. Locking the ratio at 9:35am creates stable, non-moving levels that stay consistent throughout RTH, making them far more usable for intraday trading.
Best use cases
• SPY / SPX options traders
• Index-based level traders
• GEX, gamma, and macro level mapping
• Traders who think in SPX but execute in SPY
Customization
• Adjustable SPX level spacing (5 / 10 / 25)
• Number of levels above and below price
• Label size and offset
• Live or Locked ratio mode
• Optional short line stubs
• Info table with ratio and lock status
