Parsing logic for @profit should be updated

[YuriyTigiev]

Gekko version: v0.6.6
Nodejs version: v8.12.0

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

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