Fast Stochastic Crossover Watchlist

For this answer I copied the code from the built in study, StochasticFast. I then modified the code to work in a watchlist. I added several lines of code to look for FastK crossing above FastD two bars ago. I added tests to check that the FastK is still above FastD two bars later. A positive result prints a value of +1. Once you get to the third and consecutive bars the signal returns to -1.

Hi Pete , I have a challenge somewhat similar to the one listed above with two stochastics. I plot two full stochastics with different parameters in the same frame on one of my charts. I would like to calculate the value difference between  the %K of one stochastic and the %D of the other. Ideally, I’d like the resulting value in a watchlist. I have NO coding skill so would consider a reasonable fee for the effort.

Thank you
