BacktestTool - batch backtest, import and strategy parameters optimalization

[Justaotheruser]

@st3ppin I had the same error. Did you make sure that are your file's in the same directory ? Make also sure that all your information in backtestconfig.pl is correctly fild in. I had issue's with the database. Binance did not work for some reason, Poloniex worked for me.

Thank you. Now the backtest.pl start..

First of all thanks for this great tool… and for free!!
I am quite new with programming and therefore more tan happy for getting Gekko and the BackTestTool running more or less easily.

Now I got a problem:

Although the BackTestTool seems to be working fine (by looking at the roundtrips and comparing with Gekko UI the results match), for different pairs, strategies, dates and settings I always see on the summary a PROFIT of 0.00. Nevertheless I can see the results for the best and worst trade correctly. Due to this problem, I cannot evaluate the strategies 

I have read all the messages on the forum and havent found anything similar.

I have also checked the backtest-config.pl in detail and played around with it, with no sucess.

Thanks a lot if anyone can give me a hint!!!

By the way, I am using Windows 10 and installed following the "Open Source MS Windows" (with Strawberry Perl and so on) proceadure.

PS: once I become bitcoin-millionaire Ill give the helpers a good tip

Same Problem for me " I always see on the summary a PROFIT of 0.00" with Gekko 0.6.4 or 0.6.5"

I got the solution two days ago on a different forum (https://github.com/xFFFFF/Gekko-BacktestTool/issues/35) and it works for me:

You need to change in line 1280 of backtest.pl:

my @profit = $grun =~ /(?<=simulated profit:\t\t )[0-9.-][0-9.-]* $sets[1] ((.)(?=%))/;

to

my @profit = $grun =~ /(?<=profit:\t\t )[0-9.\-][0-9.\-]* $sets[1] \((.*)(?=\%\))/;

...good luck!

I edited it like you and it worked. Great, thank you very much

Anyone knows what units should be used in CandleSize:Warmup in config file?
For example hours:hours or minutes:minutes ?

I think they are both minutes:minutes.
