Why does my expert work in ALPARI broker but not in PCM broker? Explanation: MetaTrader of both brokers is running on the same computer at the same time.
 
It depends on your EA (how it was coded), and it depends on the type of account (ECN/STP or not) you are having in both brokers.
It also depends on the trading platform you are using (MT5 or MT4, if MT5 so - netting account or hedging account).

The fact that you are running both accounts in different terminals on the same computer, is not the reason for your problem.

 
It is related about your codes and broker values
It needs recode. 
Dont you have errors in your terminal expert tab or journal.
