Can someone tell me if its give a big difference for your EA
if you are using some VPS for example that will get some <1ms latency
or when you are using 50-100ms latency
the bid/ask you see will be different , it can differ few pips between it ?
Or there is not really a big difference and won't give different results?
It depends on the EA, if its a scalping EA targeting a few pips in every trade, triggered by breakout (price action) strategies, then every ms counts.
If the EA is trading more long term with larger TP values, then its not that important.
Generally the lower the ping, the better in terms of trade execution.
