Start with product scope
Check whether the available account model supports the number of MT accounts you want to manage, and do not assume every copier routes one signal to every account.
Separate account rules
Each account can have different risk needs. Review lot sizing, allowed symbols, channel rules, and pause controls before scaling signal copying.
Review account-level history
A multi-account workflow should make it clear which account received a signal, which account skipped it, and why.
Inventory connections before selection
Record which connection belongs to which broker and platform without publishing credentials. Review the actual capacity displayed in your account. More permitted connections means more connections can be stored; it does not change the primary-account execution rule.
Confirm selection before new entries
Check the selected execution account and its readiness before enabling a channel or changing the selection. Review positions already held on other accounts directly with the broker. Selecting another account does not migrate existing positions, and an unavailable primary account is not permission to route to an arbitrary secondary one.
