Next-Day Open Bias (NDO) — Clean HUD (Compat)

What It’s Designed To Do

Goal:
Predict whether the next day’s market open will gap up (bullish) or down (bearish) — useful for swing entries into next-day expiry trades, e.g. SPX 0DTE or next-day options.

It’s a probability-driven model, not a buy/sell signal generator.
It gives you a probability bias for the next day’s opening direction.

The text color instantly tells you:

🟩 Green = Bull signal (expect next-day gap up)

🟥 Red = Bear signal (expect next-day gap down)

⚪ White = Neutral / no edge
