"DOUBLING UP" I assume what is meant here is averaging down when you are trading long, and averaging up when you are trading short..... my thoughts on this is to be patient and leave a good space between the first and second trade..... If the stock reverses before you get your second trade on, then bad luck.... its better to be much further away from the first trade where the risk of a large loss on that also is much less
can't answer how you fit that in with the stop loss, maybe some one else can.
and you need to think very carefully before doubling up on a high beta stock as I did today..
