But I found other problem. The program crashes when the output folder is not correctly set.
I'll fix it.

Please check if the input / output folders are correct.

Re: Forex Strategy Builder Professional Beta 1

works now. you were right about the output directory. I had to reset that.

I am using specially prepared expert to trade martingale as it did not work.

FST and FSB Pro are using the same Expert and Library.
Both products works in the exactly same way.

If you made modifications of your expert, they should work in the same way in FSB Pro.

Unfortunately MetaQuotes made changes in MT4 and many old experts stopped working.
I and Serfel updated the expert for FST and FSB Pro FOR FREE.

You don't have to buy anything you don't want. An you don't have to be angry for something that is not under our control.

Be sure we are working on 100% to fix all issues and to provide better user experience.
By saying we, I mean me and some other collaborators.
With selling FSB Pro, I hope I can hire developers to bring the project on another level.

I suggest you to calm down and to rest for several days. In that time you can try using some other tools for developing and testing strategies - for example MetaTrader. If you fill much better coding in MQL, greet. You don't need FSB.

If you are still our user - it's even greater.
We'll try to make your forex journey better and smoother. (in our free time of coerce. Because our main efforts are towards making FSB Pro even better)

Well yes
it is your product and your development and your time and your effort.
I just thought when you do new version you would like to fix old problems
which I have already mentioned
I think FSB/FST is great tool and I did not understand why you put so much effort in new version while not fixing the old issues.
Anyway I will stop bothering you.

Please describe this fix further.

Re: Forex Strategy Builder Professional Beta 1

Normally the developer sets the firstBar parameter of an indicator depending of the indicator mats.
For example MA with period of 16 must set minimum FirsBar=16 because before 16 the MA has no value.

The problem arises when a developer doesn't set FirstBar correctly. It may lead to a crash in Backtester due to calculation logic.
Lets see the logic rule "Indicator rises". Backtester starts from the FirstBar of the data series and calculates the signal. Rises = Value[bar] > Value[bar-1]. If FirstBar is set to 0, the program will crash because there is no Value for bar = -1.
Some logic rules need more bars. For example "Bar opens above indicator after closing below it". This logic rule requires minimum FirstBar = 2. This is not the problem for most of the indicators since the first bare is much greater value.
To prevent such crashes, I set in Backtester:
firstBar = Math.Max(firstBar, 2);
This means that the FirstBar is minimum 2. and backtester will not crash due to error in a custom indicator code as using "Bar opens above indicator after closing below it" and setting firstBar=1.

Do you mean that if developer makes a mistake in firstbar it will not crash the software but the indicator calculations will wrong and the indicator will repaint the results!!!!!

Re: Forex Strategy Builder Professional Beta 1

No repaintinting, you get funny values in the span of FirstBar (from bar 2 to actual FirstBar), after that it works normal.

One remark about "funny values" - it can be that these could be unreasonably small or large, then you'll see your old and beloved friend the overflow error  yikes wink

but that fix will mask the error so we cannot know what are indicators with overflow error right!!!!

Re: Forex Strategy Builder Professional Beta 1

This fix has noting to do with the indicator errors.  It simply starts calculating your indicators from the second bar because the logic rules require minimum two bars. FSB gives you perfectly enough spaces for your indicators to crash - from the second bar to the end of the data series. It simply will not crash in the second bar but at the third one.
I'm sure 99% of the indicators set FirstBar to a value greater than 2. So these indicators will not be affected in any way.

Even my favorite and most simple Fractal Strategy starts calculating from the 8th bar.

However, to be sure that all programs are 100% compatible, I'll make the same changes in FSB and FST.
