I have downloaded the PRT_Price Momentum Oscillator, and when I try to code a simple screener like Line Crosses Over PMO, it gives me an error “Internal server error” and is not the first time and the first indicator.
I spotted the problem, caused by the used of the choice made of the moving average type in the “average” instruction (set to mode 1 which is Exponential one = EMA). I changed the code to the “exponentialaverage” instruction instead and it works correctly now.
