Updated SPY/SPX Expected Move + Session Levels
📊 Expected Move + Session Levels (SPY / SPX)
Plots the day's expected move band plus the key session levels — automatic, refreshed daily before the open, nothing to enter or maintain.
🔹 Draws: Expected Move High/Low (the one-standard-deviation daily range implied by options pricing, anchored at the prior close), Prior Day High/Low, and Overnight High/Low (from the ES futures overnight session, rescaled to your chart). Optional shaded band and info table.
⚙️ Settings: every level toggles on/off individually; colors, line width, and label size are adjustable. The overnight source, session window, and IV index can be changed, and setting Horizon to 5 with VIX approximates the weekly move. Best on intraday timeframes.
⚠️ Note: the expected move is a statistical estimate, not a boundary — price is expected to close inside the band roughly two days out of three, and beyond it roughly one in three. Treat the edges as context, not walls; the market will go where it chooses. All levels are built from CBOE volatility indices, daily session data, and CME ES futures. Informational only, not trading advice.

Release Notes
update chart to dailyRelease Notes
no code changes - Reminder that on the expected move: it's a probability range, not a promise. Options pricing implies price closes inside the band about two days out of three — which means it breaks roughly one day in three, and that's completely normal. Use it as context for your trades, not as a wall to lean on. Your plan, your levels, your risk rules always come first.Not financial advice. Trade your own plan and manage your own risk.
