Two scenarios ...
A. I have a DC. If it hits 5% on Day 0, then great. After that, I'm happy to run it with just a timed etc. exit. To #hack this, at the moment I have to use a 5% PT, then at 15:59 change that to 999%. In backtesting it works. Most reputable brokers will reject a silly PT. I can set the PT to 100% for automation - that kinda works OK (but it's a hack)
B. If I sell a 1$ credit spread, with a 50% initial PT, but then after 1 hour I want to let it ride-or-die, I can't remove the PT. In _backtesting_ I can set the PT to 100+%, but a broker will reject that order. And we can't mix % and $ (for a CO). So the only recourse is to use a 95% PT.
It would be greatly preferable if there was an option to simply cancel the PT.
If you don't want extra buttons, then using '999%' should be a convenient workaround?
