Problem with one of my indicators (memory?)

 

I'm having a problem with one of my MT4 indicators: it's the Two_Colour_MA

When you press the home key to go further back on the chart the indicator goes crazy. Then when you go back to the current time on the chart it's still going crazy.

Any tips on how to solve this or is this? Is it programming error or a MetaTrader problem?

Note: I'm actually running MetaTrader on a windows installation which is running on vmware in Linux; I don't believe this to be an issue as other indicators are fine.

Cheers.

 

Moved. Please post only working indicator in indicators forum.

 

I can't think it being a programming problem. I personnaly have never used Home to change. Try using the page up and page down functions...
