Fixing the enclosed SymbolSignalFilter.mq5 script and add ChartOpen() function.

Fix the attached indicator. First loop runs. but there's a bug in the second one.

Beneath Print() in the script finish the implementation of the ChartOpen() function.

The indicator iIchimoku is not of concern at this stage. Any other indicator which make buy/sell signals can be applied for debugging and fixing.

No additional class must be implemented.

Of course full source code is required. (Needs to mentioned in the contract due to Metaquotes rules.)
