Running multiple EAs on Multiple Pairs for the same account

Hi everyone.

I hope I can make myself clear in explaining what I need.

I have three successful EAs which I plan to use on my LIVE account using a VPS server

For simplicity let me call them EA1, EA2 and EA3

Now, I want to use each EA mentioned above on three separate pairs which are EurUsd, GbpUsd and EurJpy.

Which of the following scenarios is the best and will avoid conflicts between the three EAS?

Scenario one:
Use all the EAs under one MT terminal with different MAGIC number for each EA. This means I will end up with 9 charts opened in the same terminal as follows:

EA1 on EurUsd chart, GbpUsd chart & EurJpy chart
EA2 on EurUsd chart, GbpUsd chart & EurJpy chart
EA3 on EurUsd chart, GbpUsd chart & EurJpy chart

Scenario two:
Use one MT terminal for each EA which means I will end up with one terminal for EA1, a second terminal for EA2 and a third terminal for EA3. The situation will look like this:

Terminal-1 running EA1 on EurUsd chart, on GbpUsd chart & on EurJpy chart
Terminal-2 running EA2 on EurUsd chart, on GbpUsd chart & on EurJpy chart
Terminal-3 running EA3 on EurUsd chart, on GbpUsd chart & on EurJpy chart

Scenario three:
Use 3 MT terminals similar to scenario-2 but run 3 EAs on each terminal. The situation will look like this:

Terminal-1 running EA1, EA2 and EA3 on EurUsd charts
Terminal-2 running EA1, EA2 and EA3 on GbpUsd charts
Terminal-3 running EA1, EA2 and EA3 on EurJpy charts

Due to my limited experience in MT terminal I am not sure which of the above scenarios will work well and avoid any conflicts between the EAs.

I would appreciate receiving your advice.

IMO Scenario 1 would be the cleanest and easiest to implement. You shouldn't have an issue if you use your magic numbers. You will of course want to demo it first to make sure there's no conflict.

I've run many EA's, especially trade management ea's, that way and not had problems.

Are you using a US broker? If so, keep in mind that if you're running multiple EAs on the same pairs in the same account you can run into FIFO and hedging issues.

For example EA1 might signal going long EURUSD and EA2 might signal going short EURUSD at the same time. A US broker won't let you be long and short the same pair in the same account.
