So, when that guy was doing this with forex, his net profit was $0 no matter what happened prior to closing the unprofitable side, in which case he just paid more comissions to have $0 net profit against just doing nothing until he psychologically picks a side and adds in this way. Of course, market can instantly reverse as soon as you determine which side is profitable.
For example, price is 1.1000. He goes long and short at 1.1000. Price gets to 1.0000 and he says "ok, short is profitable" and closes out his long position. He now has a $0 net gain minus three comissions, but to open long, sell to open short, and sell to close long. He could have just waited until price got to 1.0000 and gone short, had exactly the same net gain, except only paid one commissions, and come out ahead.
Does doing this with options change something? Are you waiting until one leg is profitable or are you waiting until the stock is profitable? For example, if you buy $48 puts and $52 calls, let's say the position becomes profitable at $46 and $54. Do you wait until a net profitable position, or do you wait until either sort of option is profitable on its own, but not overall? In other words, if the $48 puts would become profitable by themselves at $47, do you start adding more at $47?
