How many EAs do you run simultaneously — and how do you handle conflicts?

[Tsvetan Tsvetanov]

There are too many variables. There is no right answer. It depends on the type of EA. And also on the hardware. In theory you can do anything if you know how. Otherwise it's a mess. To run multiple different EA's in one account, you have to control the EA's with magic numbers and split the account balance into virtual parts.  Each EA gets it's own capital allocation and the risk is managed accordingly.  If you have the source codes, you can combine all EAs into one. But you also have take into consideration the limitations of the account like max open trades, max total volume and margin requirements.  In most cases it's better to run each EA in separate account. Just to avoid the complications and the potential for errors.

You just have to.... A shared resource

An EA is merely a program type in MQL5. For example, an EA can be coded to trade, draw like an indicator, or generate Custom Symbols/charts. I'm always running 2 EA's simultaneously, but never more than one EA that trades. In this way, I would probably have to intentionally code such a conflict in order to experience such a conflict.

I'm not sure how to vote in the Poll because I use 2 EA's without manual intervention, and that option doesn't appear in the OP.🤷‍♂️

What's there to be conflicted?

Just run 1 EA on 1 terminal/account and upload each account up to myfxbook for tracking. At the end of every trading period (e.g., weekly/monthly) just check in to see the results.

Emmanuel Christian Aliouat:

• 1 EA only — no conflict issues

  27% (3)
• 1 EA per account — I prefer splitting my capital across accounts

  9% (1)
• 2–3 EAs — I manage manually

  0% (0)
• 4+ EAs — I built my own coordination logic

  64% (7)
• 4+ EAs — honestly, it's a mess

  0% (0)

I run 1 EA per account, both the EAs I built are great they do what they are supposed to do...
