One thing I have noted is that different platforms will show different daily trends. For example FXDD has shown GBP/JPY to be in daily uptrends for the last 2 days whereas Oanda shows 2 clear downtrend days -simply because FXDD days begin at 22.00GMT and Oanda's at 04.00GMT. It appears that providing you stick with a preferred broker this shouldn't be a major issue as FXDD shows a lot of very nice trending days up and down which should still prove very profitable...
