SPXU appears to not be effected by TSPP, as I see bid ask prices for penny increments. I'm not sure any other definitive way to tell without actually attempting to enter an order.
However, options for SPXU are limited to 5 cent increments. Why is this?
Is there a way to easily tell if something is TSPP without scanning bid/ask prices or attempting a trade?
By TSPP I mean tick size pilot program that sets a 5 cent increment for small cap stocks. I'm only guessing this is why these options are limited this way.
