Rather that use a MTF psar, which could change before the 15 minutes are up...would you be better to use the same psar indicator with a setting that mimics a longer timeframe? It might look something like this..plus the slope direction line. Only one spot today where you get caught in a bit of whipsaw and you would have made it back easily.
