DislikedI have yet to see a system that cannot be tested in MT4 using tick data - including multiple symbol (basket) systems like this one. You just need to think outside-the-box a little bit.
In fact, I will go as far as to say you can backtest any system using just about any programming language. It's simply a question of how technically strong you are and how much effort you want to put into it.Ignored
I could download the Dukascopy data, convert it to renko and output as a csv file by modifying the renko script, and then change my EA to read the CSV file instead of the MT4 history. By the time I figure out how to do that I think I'll be able to learn enough JForex to do it more elegantly with their API. After all, with renko charting included in the API, the strategy itself is very simple.
