Breakout confirmation

Fires once price has closed above a level for N bars in a row, on the bar the run reaches N.

It counts how many bars in a row price has been above the level and fires on the bar that count reaches bars. It fires once per run: later bars of the same run stay empty, and a bar at or below the level starts the count again. The level input has no default; on this chart it reads the close, which is never above itself, so it never fires here.

How to read it

Markers sit on the candles on the bar each run above the level reaches N bars.
In a strategy, bind the level to a resistance line, such as a 20-bar high or a moving average.

What it outputs

Confirmed breakout: On only on the bar a run above the level reaches N bars.

When it fires

On the bar where price has been above the level for exactly bars bars in a row. On this chart the level is the close itself, so it never fires.

Settings

bars: How many bars in a row price must hold above the level. More bars wait longer and skip short pokes above it; 1 fires on the first bar above.

Pitfalls

It fires once per run, so it marks the confirmation, not every bar price stays above.
Confirmation costs bars: the entry comes N bars after price first got above the level.
