Why do same strategy differ so much from 1 broker to the next

Why is there such a difference in the wins, losses and when the strategy buys or sells between the different brokers.
Oanada and Interbank FX)
I'm just trying out PSAR on daily chart and back test for about one year since Oanada only seems to go back that far.
Although the strategy always seems to win alot more pips than losses.
The different brokers vary so much.
Is that just the way it is?
One broker wins more on USA/GBP and the other broker wins more on AUS/USD.
I guess it all evens out in the end.
I haven't even got into who has the better spread.
I'm just back testing and demoing different brokers before i use real $$$$$$$$$$
