I have one mt4 account, always trade the same currency pair. For buy, I may trade a few buys with increased lot size. Same as for sale orders.
Here is the exit criteria:
assume directional trending, all buy or all sell positions.
1. if only one position, say buy, P1, if the loss is over 0.2% of the account balance, exit.
2. if there is a second buy position in the account, assume p1 and P2, and P2 lot...
