I am a regular with USDJPY too, find the analysis by heikin ashi very useful here. Even with GBPCAD I have gotten good results.
EURUSD is good to trade between 1 and 3 afternoon hours, when both London and New York markets are open.
Best time to trade would depend on a lot of factors, the trading style adopted is one. As a day trader, for me anything before 8 in the evening works. After that till upto 7 in the morning there’s not much pips movement.
I currently trade with EURUSD the results are good but looking for another alternate currency pair with London timing any recommendations?
