Hi all, 

I've tested a fairly simple technical analysis model on Crypto currencies. I noticed quite a strange thing, when switching brokerage model (GDAX vs Bitfinex) the results differ significantly, from 20% PSR to 37% PSR. Looking more closely at the orders it seems to mainly come down to a somewhat different price from the two brokers, also occasionally resulting in a different order as the indicator will differ. Is this purely down to arbitrage differences between the brokers or could there be something else here? 

 

Anyone having some more experience with this, as with such difference it makes it hard to know if the results are reliable.
