"Flatten All" vs "Exit on Close"

[dtf139]

I am running a strategy on multiple stocks that takes trades during the day and I use the "flatten all" to exit all positions and disable all strategies at 12:55pm. I initially was using "exit on close" at that time but my strategy was re-entering trades after 12:55 and I would end up with open positions after market close. My problem is that when I re-start my strategy every morning some of the strategies will be "yellow" and will not execute when there is an entry signal. I think its because I still have open "historical" positions. Is this because I am using "flatten all" ?. If so can you explain the underlying logic of whats going on?

Thanks

dtf139, I would expect that - if you did not exit historical position from the prior day the strategy would still wait in the morning for those to be exited by your rules before trading a new live entry (provided you use WaitUntilFlat as mode for starting them up). I would use the ExitOnClose and include a custom time filter in the script that would not allow for any entries after your 12:55pm.

Thanks Bertrand,

Instead of ExitOnClose I added a time exit to my strategy that exits the position 10 minutes before the close and that seems to be working perfectly since I implemented it.
I also am still using "flatten all" about 2 minutes before market close. My thinking is that if for some reason my strategy crashes and I am left with an open position the "flatten all" will protect me. Is that an accurate assumption?

Thanks for the feedback, glad to hear. Correct FlattenAll would still work on the account level then.
