Holding a portfolio of currency pairs

A trading friend and I have recently been using a new approach to trade where we collect multiple currency pairs when the entry signal permits instead of just focusing on one or two. Instead of closing the trades by the end of the day, we hold them till they reach our target price. By entering smaller units, we can trade without a stop loss and in the event our entry was wrong, we can use a staggered approach or hold the currency pair till it reaches profitability.
