Coding an EA: Basic Question

 
I'd like to convert a trading system that I am using into an EA for use on MetaTrader 4. One of the indicators is a proprietary indicator. Is it possible to create an EA around this indicator without the source code for it?

Could you get the owner of the indicator to output to a file? Then you could code your EA to read from the file.

 

I'll check with the owner concerning outputting to a file. I've coded an indicator that reads from files, so I understand your logic. Not sure if the owner will do this though.


An arrow is painted on the chart to signal a trade. Could this be used by an expert advisor?
