Due to the fact there is no central bank controlling Forex, brokers have slightly different price feeds, different spreads and different degrees of slippage (the difference between when you want to get into the market and when you order is actually filled). In the vast majority of cases, these small differences do not make any difference to the trade results.
These discrepancies are broker issues, not signal issues.
Since we are not placing the trades at the EXACT price levels, it is likely results will vary a little bit. But since we are going after 100’s of pips, these small price differences (either for or against you), will not make much difference to the overall performance of the signals.
On rare occasion, it might be possible for these slight pip differences (spread, entry price, etc.), to cause a signal to hit a stop on our account and not yours, or vice versa. This would be the only occasion for there to be a major difference in performance. But this would be vary rare, and in my opinion not destroy the overall performance of the signals.
I just wanted to bring this to your attention.
