I don't have an answer for you Johnny. I've been watching Mytrack and oanda tick by tick for about an hour a day for several weeks. Sometimes one leads, sometimes the other (usually oanda). By the time the one min bar is done forming they are usually in sync.- so you wouldn't know it to look at the chart after the fact, but when markets are really volatile, oanda seems to get their first. Today on the eur/usd there was 4 pips difference for about 10 seconds, then my track caught up. The other thing I have noticed is that occasionally oanda shows a wobble, and sometimes a spike that is a pip outside mytrack. It's almost as tho mytrack was using some kind of smoothing algorithm, or tossing out the occasional outlier.
weird.
