how many EAs is too many on one account, mine keep fighting over margin

[Jake]

i have four EAs on one account and theyve started stepping on each other. one opens a big position and suddenly another cant take its trade because margin is tied up, or they both pile into correlated pairs and my risk doubles without me realising.

is there a sane way to run multiple EAs on one account, or should each get its own account?

[Dean]

the correlated-risk problem is the dangerous one, not the margin contention. four EAs that independently decide to go long eur, long gbp and long aud have effectively made one giant dollar-short bet while each thinks its taking a small isolated position. either run them on separate accounts, or build a portfolio-level risk layer that knows the combined exposure. margin you can manage, hidden correlation blows accounts.

separate accounts is the simplest clean answer because each EA then has its own margin and its own drawdown limit and they physically cant interfere. the downside is capital fragmentation and more to monitor. for most retail traders separate accounts beats trying to build a coordinator they dont have the skill to maintain.

four EAs and you dont know your own total exposure. thats not a margin problem, thats not knowing what your money is doing. adding a fifth account wont fix the fact that you outsourced understanding your own risk to four black boxes.

ran into this exact mess years ago. solution that worked: a shared risk module all the EAs query before opening, it tracks total exposure per currency and refuses a trade that would push combined risk past a limit. it was real work to build. if you cant build that, the troll is right that separate accounts is the honest fallback, not a fancier single account.

if i split to separate accounts does that mess up the prop firm rules, or is this mostly a personal-account concern?

[Dean]

depends on the firm. some prop firms forbid running correlated copies across multiple of their accounts because it games their risk model, others are fine with distinct strategies. read the specific firms rules before splitting EAs across funded accounts, getting flagged for prohibited correlation can void payouts. on personal accounts youre only answerable to yourself.
