Cool thanks! I can instantiate a new Process object, call the .Start() method and save the unique process id for checking (allows me to have multiple terminal.exe's running). And there is even an .Exited event. Perfect!
Be careful if you are planning to run the terminal.exe multiple times in parallel, since you are sharing the same directory path and therefore result and set files can overwrite each other.
To perform parallel processing and take advantage of modern multi-core cpus I had to write my own backtester.

Another thing I forgot, the terminal.exe cannot be run in several instances. On the internet you can find "patched" versions of the executable allowing this.

Does your backtester test/run MQL scripts? Did it use .HST files? If not, what type of datastore did you use for historical price data?

I have one EA I trade, with several strategies in it.
A separate program translates it to a format I need to implement parallel processing.
Then it can be directly used by the backtester.
I use tick data from Dukascopy.
I build my own hst files from the tick data.

...this part definitely seems very non-trivial

It really depends on how you decide to implement parallel processing

Hi asasa,

thanks for all the info ! Could you be so nice and post the code you use to parse the html data. That's a bit tricky to me..

Thanks
Alex
