The most important thing for me is to avoid silly mistakes, that's why a wait some times and miss some good scalps and trend moves. But if I am scalping all day one mistake can cost me 2 scalps, since I don;t know how to use a small sl. I always use a hard sl of 15 pip, and once in the trade i Manage it to the actual risk. But at the same time I know in most cases where a proper sl have to go and if it is more than what I can afford I just don't take the trade.
That's why I have to work on your 1 min set up.
