Hi VJF Team,
I've meet the awesomly-slow historical testing starting (I assume it downloads the tick data to my computer), how can I speed up that?
1 day testing takes ~1 hour of preparing The internet channel is really wide (30Mbps)

Hello

could you please provide your strategy so we can analyse it. It could contain some loops, or use 100 instruments, or load useless data, etc.
If it does not come from your strategy, so we we can investigate forward.


Even if my father's 48 kbit/s first analog modem it wouldn't take that long .

Hello,

What's the most important in testing speed? During some backtests my CPU is used in 90%. It will be faster if I use 2x or 4xCPU workstation (will backtesting processor use it or not)?

Greetings!

It depends roughly from your code:

If you calculate very much based on tick than the speed will significantly slow down.
My recommendation is always that you test your strategy on VJF to see whether the entries and exits are correct. If so, compile it and run the strategy on JForex platform - this is much faster; maybe without "Visual mode".

Edit: When you want to run it on JForex, please close the Visual Strategy Processor in the task bar, because it is very resource-consuming.
