Although commented, I don't quite understand the meaning of "// mark appropriate exit code". As far as I know, the sell function is executed according to either 1(true) or 0(false). How does this code work to only sell when the exit is => 2 which is when secondprofit target (exit code=2) and trailing stop (exit code=3) are crossed.
