Esignal vs retail broker prices - help!

Hi,
I've been with my retail broker for well over a year and I've been very happy with them till now... because I've been trading some shorter time frames and have been paying far closer attention to the prices.

What I've noticed is that my retail broker prices seem to be a compressed version of the Esignal feed. By that, I mean, the retail highs aren't as high, and the lows aren't as low.

I'm skeptical that it's price shading going on here, but it does seem odd. The amount of compression ranges from 2-6 pips at both ends. All pairs.

Even if it was shading, wouldn't that help as many people as it screwed and therefore be irrelevant?

Any thoughts as to what's going on?

EUR@A0-FX is the "composite" Eur/Usd datafeed - means all institutions that are sending quotes to eSignal are in there. Its pretty useless for intraday charts, use a contributor specific symbol instead. For example, EUR@TDFX A0-FX is only the MB Trading data. For a complete list of FX contributors see esignal support pages.

Shrike, thanks - that's a massive help.
I'll get on to it.
