DislikedOanda is good for live trading, i think for demo trading it would be better with MT4, Alpari for example it doesn't matter, and about EURGBP it's one of the most unpredictable pair at all it's highly corelated with e/u and cable and it depends on these two pairs, my coleagues with 10+ years of trading experience in bank told me to never trade eurgbp they 've never traded that pair and I can tell you to not do it too, try to focus on eurusd, it's the most traded pair with best liquidity, there is not a lot of spikes or noise....Ignored
its definitely not a beginners pair
