I'd love the ability to change the PT based on time, including the ability to turn it off. Lowering or raising the PT after a period late in the day is very beneficial for some trades. An example would be iron flies that are close to expiration and a user wants to turn off the PT entirely. I have a trade that re-enters after a PT but late in the day I'd like to turn off the PT entirely and avoid the extra fees. These features are available for backtesting in OO, so it'd be great to be able to automate them.
