Same EA with different results on different brokers.

 
Hi, I am testing my Gold 1 minute EA, and it's giving me different results on different brokers though all brokers I am testing are ECN and good reputable brokers but at the end of the day results are always different. I understand there is always price and order placement difference but still some deals entirely go off the record.. it's not hft or arbitrary EA but purely strategy based and holds deals for 3 to 5 minutes. Thoughts for this?
