Post subject:  problem with historical tester
Hello.
I have some problems with the Historical Tester in JForex platform. I have created a simple strategy in the Visual JForex and exported it to my PC.
If I'm not using optimalisation, the strategy works as expected. Trades are opened and closed upon strategy request.
During optimalization something goes wrong and my SELL orders are closed by STOP LOSS just few points (not even pip) from the open price.
I don't have any trailing stop in this strategy, Default stop loss is 200 pips and take profit is 1005 pips.

I also have similar problem with the same strategy but with added trailing stop.
The strategy works fine with trailing stop 0(no TS), 30 and 60 pips.
As soon as I start optimalization my SELL orders are closed by STOP LOSS just few pips from the open price and on the wrong side (so it's not from trailing stop).
In some cases trailing stop worked fine, but there are much more closed orders from something else.

Have you encountered with something similar?
Or have you any idea how to solve this problem?

Thank you

I am pretty sure that without seeing the actual strategy code, there is no one who could give you help.
As you have issues with optimization, I suggest to attach a screenshot from your Historical Tester's setting, together with the strategy that behaves wrongly.
If the strategy is confidential, you could send it to [email protected], so they can investigate, without making it public.

Hope this helps to get you further.

Ok, let's keep it simple.
I have created simple strategy in the Visual Jforex. It is just cross of two EMAs and one RSI. The code is in the attachment.
When I try to run this strategy using historical tester everything is OK. (test.html in .zip file)
But if I want to use optimalisation most of trades is stopped immediately. (test1.html in .zip file)
I just check optimalization option and nothing else...

I'm using JForex platform version 2.31.1 downloaded yesterday.

Hello
I have another problem with historical tester.
Strategy has been created in the Visual JForex.
Results from testing in Visual JForex are completely different than results from JForex platform.
Results from JForex platform are in html files for "last week" (test2) and "last month" (test3) period.
Results from Visual JForex are in txt files, same name, same periods.

Why are they so different? Which are correct?
Why wasn't there opened any new trade after 2014-01-07 even if the trade was closed by strategy request and another trade should be opened automaticaly?

Dukascopy Bank ver. 2.31.1
JForex API 2.9.6.1
