Coder Help: Indicator makes EA run very slow

I had a coder Alexander Voronkov from Ukraine helping me by adding two MA's to a EMZ indicator (EMZ-MAs.mq4). Unfortunately I have not been able to get a hold of him for almost two weeks. My fingers are crossed that he and his family are safe.

It worked on live charts, but it did not work in the Strategy Tester. The error that shows in the Journal when running the EA: "EMZ_MAs GBPJPY,M15: array out of range in 'EMZ_MAs.mq4' (76,36)"

jeanlouie was kind enough to fix the "array out of range" issue, (EMZ_MAs_mod.mq4) but now it runs extremely slow in the Strategy Tester.

Two questions:

1. Because it's running so slow in the tester, when I load it on to a chart is it going to increase the workload on my PC?

2. At this point I can't use it for back-testing. Can anyone take a look at it to see if it's an easy fix.

EMZ_MAs.mq4 = array out of range
EMZ_MAs_mod.mq4 = Runs very slow in ST

I seem to have it working at this point

It's working better now, also added an option to use the orignal calc, flipping between the two in the tester has a stark speed difference.

Thank you very much.
