I have never used a strategy in TS so I will defer to BlueRay
Hopefully will learn something too. There are a bunch of reserved words to buy sell etc. that I guess would go in instead of plot.
Easylanguage really is pretty easy (IMHO) and a bit of hands on will get you there in no time at all.
Perhaps look at one of the sample strategies to see how it hangs together. Im sure there must be one for a moving average Xover or something similar.
Be interested how it pans out for you.
