Max holding time exit

Marks bars where an open position has been held past its time limit, a cue to exit.

The indicator watches a position input that is empty when flat and filled while a trade is open. It notes the bar a position opens, then counts the bars since then at 60 seconds each. Once that count reaches max_seconds it returns True on every bar until the position closes, and it places no orders itself.

How to read it

Markers show only while a position is open and has been held max_seconds or longer.
Read the first marker as the time-out bar; later markers repeat on each bar the position stays open.
No markers means flat, or still inside the time limit.

What it outputs

Time limit reached: True on each bar where an open position has been held for max_seconds or longer. Other bars draw nothing.

When it fires

When an open position reaches max_seconds of holding time. That bar is the time-out: the trade has run past the limit, so the strategy or trader is due to exit. Markers keep appearing on later bars until the position closes.

Settings

max_seconds: Holding time in seconds before the flag turns on, counted as bars times 60, so it is exact only on one-minute bars. Raising it lets trades run longer; lowering it flags them sooner, down to 1 second. Default 7200 is two hours.

Pitfalls

It only flags. Nothing closes the position unless a strategy or trader acts on the marker.
The Cython build treats a zero input as flat and keeps an old position open when the input goes empty, so it can disagree with the reference build.
On the sample used to check this indicator, the position never closed, so the flag sat on for 99% of bars. Real hit rates depend on how long your positions last.
