EUR/GBP I found is the best pair for me - I like trading in corridors with Keltner channel + RSI. Lazy currency pair for intraday trading, but 20-30 pips, when trading in corridor, it gives.
I found XM is good for long-term trades, because of no swaps acc, so I can sometimes hold my position for an entire week, even did it for two. Would have to close in losses if I was with a diferent broker.
