Scheduled start and stop

I'd like to define when a strategy is allowed to run, once, rather than remembering to arm and disarm it. Concretely: start at a time I set, stop at a time I set, skip days I've marked. The manual version works fine until the morning I'm distracted, and the failure mode of forgetting to stop is worse than the failure mode of forgetting to start. Bonus if the no-trade calendar is a list I can maintain rather than something I toggle daily.

"Forgetting to stop is worse than forgetting to start" is the argument that should carry this.

For crypto I'd want the opposite emphasis. Scheduled stop matters even more when there's no close to stop you.

Logged it. Two things that decide the shape of it: whether the times are wall clock in your timezone or relative to the session (open+15m etc), and what should happen to positions that are still open when the stop time hits. Flatten, or just stop new entries? Those are different features and we'd rather build the one you actually mean. Also worth saying half days and DST are where these things usually break, so no promises on timing.

The framing I like here: a stop time is just a cap on exposure expressed in hours instead of dollars. You already limit how much per trade; this limits how many trades the day can hand you. Same idea, different axis.

Curious how you'd know it worked. If the schedule silently fails to stop one morning you'd only find out from the fills. Would want some record of 'armed at X, disarmed at Y' per day so you can check it against what actually traded, otherwise the calendar is just a thing you believe in. And Karl's point makes that harder. No close means nothing else catches the miss.

stop new entries. don't flatten. a forced market exit at a fixed clock time is its own bad trade. if i wanted flat i'd have a time exit in the strategy itself. also whoever builds it, watch the dst weeks. relative to open is the sane default.
