Hello. Still trying to work with MT4 indies, and there is a recurring problem I am noticing on all of my scripts, and I'm sure the fix is obvious and simple.

I've been trying to create an expert advisor which will automatically buy 1 unit when the tenkan-sen>kijun-sen (when the tenkan-sen line is above the kijun-sen line) and then sell it once the tenkan-sen is lower than the kijun-sen. I'm a complete newbie and started it yesterday by trying to piece
