I only trade one currency pair - EUR / USD. The advantage of one trade with only 1 pair is that I can concentrate on this couple, I know the history of these couple's tides perfectly can be the idea of a trend without knowing the fundamental analysis. I usually follow 1 hour and 4 time frames. But when the market fluctuates, I follow the 5 mintues chart. I use moving averages, bollinger bands and ADX only. and it is always better to follow behind my pair of say ... i used to trade aud / usd, usd / jpy, eur / usd, nzd / usd ..etc .. but soon you will end up no ... bcoz it will be difficult to manage things ... it will be very difficult to analyze all the pairs ... so i am now just trading eur / usd ...
