Any Idea Why This Indicator Freezes?

[Forex Trader]

Hello,

Does anyone have any idea why this indicator doesn't work? It loads and then simply never refreshes with new time bars. It's the same on any time frame.

I'm using MT4.0 Build 203

Very perplexing.

Thanks for any help.

Check for i value. I suspect it is negative

[Forex Trader]

Yes, I'm sure that i value is negative. Also see this article on Russian http://old.alpari.org/ru/experts/articles/16.html

Thanks for responding guys.

A few problems. I'm not a programmer nor do I speak Russian.

Can anyone else provide a hand on troubleshooting this?

The interesting thing is I've found more indicators that don't refresh. I reinstalled MT4 but no joy.

Thanks for any help that can be provided.
