Why Does Removing ONE Line of Unused Space Cause Profits to Reappear?

So, I was running a system “MBFX Belkhayate” and then decided to apply machine learning (ML) to it last night, I called that one “MBFX Belk ML2.” I got around £1,700 profits in the ML version and £1,800 in the non ML system. (The ML had better stats but slightly lower profit). Long story short, I spent about an hour altering some MBFX Belk ML2 system starting values and max value settings, adding pProfit targets etc. BUT, when I went back to the original MBFX Belk ML2 settings I couldn’t get the £1,700 profit anymore? It was losing money. I tried for another hour to replicate the results, stripping out ML code and repasting it back in just as I had when I first created the MBFX Belk ML2 system. Nope, still losses…. So…. I started taking out chunks of ML code from the ML system this morning having given up trying to replicate the original ML backtest results last night. Eventually I got to what I thought was a near identical version of the non ML, “MBFX Belkhayate” system. But still the MBFX Belk ML2 made losses. The code looked the same because everything superfluous was “//” out (pls see first image). I went further (2nd image), nope. still losses!? So then I removed one line of unused space between the “DEFPARAM…” (line 2) and the “//Conditions to go long” (line 5) and NOW the profits are the same. Huh? Why does one line of unused space have such a massive impact on profits? This would also explain why I’ve had this issue many times before when I couldn’t match profits with previously screen-shotted versions of systems. Thanks for any insights, because this kind of issues has cost me days of wasted time over the years!

Is this Issue still hampering your good efforts Bard??

Thanks for asking, it’s slowing me down a hell of a lot. I’ve still got the VRT and Excel to sort out and learn… and the continued devo of these great ML algos.
75% of my time is trying to figure out if I’m incorrect (as I have been plenty of times getting to grips with PRT), or if it’s PRT. Difficult to forget when it’s happening daily!

As far as lost/temporarily missing indicators/systems, crazy looking templates with missing charts, it’s definitely PRT. As for the one spacebar issue and removing that tiny invisible indent, I can only say that ‘s exactly how it occurred although I understand if people doubt it because it doesn’t or shouldn’t make a difference to how a system’s code would / should run.

Even time spent on things like the grey incorrectly appearing on the Bollinger band indicator on 1,500 units but it works and multicolours the BB on the 1,000 units confound me. It just all seems so illogical? That’s another 1 hour of my life I’m not getting back!
