Well, then carry out medium to long term trading...i.e. buy/sell and hold position(s) for say 4-12 weeks or as long as is necessary.......Calculate the number of pips target to average 50-100 pips per day and wait for TP to be triggered.
A potential trade might be for USD/EUR because parity (i.e. 1:1) is widely expected to happen sometime in the future and, with much anticipated first FED rates hike in Dec'15 and further rates hikes in 2016, parity might indeed happen as expected.
Furthermore, with recent Paris terrorist attacks and the ongoing Middle East migrants problems, that might be further catalyst for parity to happen sooner than we anticipated.
However, long term trading require a lot of self control/discipline and patience which, unfortunately, most retail Trader simply doesn't possess as they are a rather impatience lot and wants to cash/lock-in profits
