Hi majed - I only have a Demo account with them. I like the platform though they don't guarantee fills and stops. I don't know if there data is 'smoothed' for Demo. What I mean by that is some brokers / SBs like CMC have fewer price moves in the Demo so it looks easier than the real thing. Might be worth asking Oanda. Also, I don't think Oanda do a GBP account.
