From what I've read, Pyramiding seems to be a paramount part in developing a profitable system.
However, with regard to a mechanical system, how would one add to open positions?
Would you wait for another identical buy signal to be generated by the system while still in the current trade? If this is the case, then what would happen when a sell signal is generated? Would you close only the first position, or both of them, or would this decision be defined by backtesting?
... or am I totally wrong here??
Any Help much appreciated.....
