Bars Since

What it does

Counts bars since the wired condition was last true: 0 on the firing bar, N for N bars ago, −1 if it never has.

What happens

Each candle it checks the wired condition and updates the count. The output is a bar count, not a boolean.

When to use

Cooldowns ('no re-entry within 5 bars') and time-based exits.

Gotchas

• −1 means it has never fired — guard for that before comparing.
• Wire a boolean condition as the trigger, not a number.
