C2 Discrepancy (Update)

I contacted TAB to inform them about the Collective2 discrepancy I wrote about earlier and they had this reply:

Hi Travis,

Thanks for the link. We have read your C2 Discrepancy comments and we should say C2 is correct. Here is the situation for that GBPUSD trade:

As you know we are trading TAB thru Oanda for our own accounts and Managed Accounts, because Oanda spreads match with our signal generating software (actaully Oanda spreads are tighter but we base our trading decisions on signal generating software's spreads). So our first profit target was 1.9736 at Oanda, but since C2 spreads are wider, we widen our entry/exit levels by one pip to match original signal values. Therefore, we put 1.9737 at C2 and FX-Auto (we use the same spreads at FX-Auto and C2). Actually 1.9737 ask rate was hit on our signal generating software but since FXCM uses variable spreads (and probably tighter), 1.9737 ask rate didn't hit on FXCM or FXDD and 1.9736 ask rate didn't hit at Oanda platform. As a result, 1.9737 was hit only at C2 and all other clients had full profit trade on this one. Sometimes this happens in opposite way and while C2 clients benefit FX-Auto clients suffer. This is a result of spread difference among different brokers. It has nothing to do with underestimation of
our results by C2.


So, in the defense of Collective2, it seems that this is something that happense from time to time and can go either way.
