i admit to naive ignorance about the answer to this question - ahh bliss for instance closed H - L prices on fri nov 13/09: MT4: . . . . . 1.4936 - 1.4824 Oanda: . . . 1.4939 - 1.4825 Globex 6E: 1.4937 - 1.4823 there's a variance between the price movement of the 6E and eurusd - mt4 - and either one can lead the other, but the 6E has the tendancy to go a pip or two H / L at the end of a wave, also mt4 and Oanada quotes tend to be 2 pips above the 6E who's setting the price ? at least at the 'start of the day' i only recall one large down opening on the Sunday after Saddam was captured - opened down 100+ pips, who decided that ?
