I am long here (from about COMP 2034). I can easily double up, and lower cost basis, but I like to use that "doubling" power as a reserve if I am really off, and to double to help me get out of a position on a bounce- minimize loss (not to create bigger, "greedier" position).
Since I only trade (low) % of capital, never too big a hit on any one trade.
Writing was on wall this morn that this thing was struggling.
The morn up told us that (yet I couldn't pull trigger). Coulda got out close to even.
However, quite a few guys I respect think we can bounce into next week, so I think I can cover flat in a worst case- but this is beginning to test patience a little (COMP looks really crappy today so far)
