Not¶

Signals · Logic

Invert a boolean signal.

Not inverts a boolean signal: true becomes false, false becomes true. It's the small but essential logic block that lets you express "when this is not the case" — trade only when the market is not in a high-volatility regime, enter only when price is not in premium, and so on.

How it works¶

The block takes a single boolean In signal and outputs its opposite on every bar. That's all — one input, one inverted output.

When to use it¶

Use Not to flip a condition without building a separate inverse comparison. It's cleanest when the condition you have is naturally expressed one way but you want the other side: invert an "in premium" signal to get "not in premium" for long entries, or invert a "trending" flag to find ranging conditions. Combined with And, it's how you add exclusion rules: "enter long AND NOT in an exhausting regime."

Example¶

Exclude a bad regime: take a Volatility Regime "exhausting" condition (built with Equal against the exhausting code), invert it with Not to get "not exhausting," and And it with your entry so you never enter into a blow-off. Route to a Buy Signal and backtest in the Tester.

Tips & gotchas¶

One in, one out — the simplest gate, but it keeps logic readable.
Great for exclusion rules in an And chain ("… AND NOT …").
Inverting a state stays a state; inverting an event is rarely what you want (it'd be true on every non-event bar).
Double-check intent — "not oversold" includes both neutral and overbought; sometimes you want a specific range via Between.
