Post subject:  Jforex tester runs too slow
Hi, I am trying to test several strategies, but I realized that the jforex tester runs sometimes quicker depending on the messages in the Java console. Sometimes the tester just stays in a percentage level (e.g. 40%) and does not run anymore, or it takes a lot of time to overcome that testing point (delay time could be 10/20/30 minutes).
The message I receive ais this:
24.03.2014 14:35:54.501 WARNING connect.cu ] White Label Image is not received

(I attached full java box message)

I bought a new PC in order to increase the speed of testings, but it seems as the javatester runs the same in any PC, and I think is because of a bug.

My PC:

i4770K
16GB DDR3 RAM 2400
HD Toshiba 7200 RPM
ASUS Z87PRO MOTHERBOARD

I test the same strategies in my laptop (which is pretty slower than my PC) and I get the same testing average time.

Testing mode:
-Last three months
-Ticks
-No visual mode and no optimization

What is the problem? Is it a problem of historical tester? Or it does not matter how fast a PC is?

Thanks,

Greetings!

Did you try to run the strategy on JForex? It should be much faster...

If it is on JForex also extremely slow than I kindly ask you to send the strategy.

I will contact a developer about this - it is probably because of historical tester, indeed.

Hi Dirk, thanks so much for your answer. I am testing on Jforex. I think that it is taking so much time because of the downloading of Tick data from Dukascopy server, because after I made a test during a certain period of time (e.g 2005-2006), if I do it again between the same period (2005-2006), testing time is pretty much faster.

Is it possible to convert Dukascopy tick data.csv which you can download from here: https://www.dukascopy.com/swiss/english/ ... storical/# into .bi5 ? (The last one is the file extension that Jforex uses in cache).

If the first option is not viable, is it possible to test in Jforex using csv data or hst data from Dukascopy?

I will really appreciate if you can hepl me with this.

Thanks,

Basically, if you run or test a strategy a second time over the same period then it should be way more faster, indeed. Because you need to cache the feed first and then, once it is cached, things speeding up.
But as said before in my presentations, try to build your strategy as efficient as possible meaning not using too many resources (CPU, RAM, Tick-info).

It is possible, but very complex.
If you want me to have a look at your strategy, please send me it. Maybe I can improve the logic a bit.

Cheers

Thank you so much, in fact, for some reason after serveal days of testing, now testing on tick data (all ticks) take 1 or 2 hours depending on code.

Thank you guys for your help.
