Merging Funded Prime accounts is allowed in certain situations. Firstly, the accounts to be merged must be of the same type, for example 2 x 2-step accounts can be merged, but a 1-step account will not merge with a 2-step.
In order to merge, both accounts must be new, meaning there must be no open or pending trades on either account and neither account can have a negative balance.
If the accounts to be merged have a different pay-out split, then the final merged account will assume the lower split.
For example, a $50,000 account with a 90% split merges with a $200,000 account with an 80% split, the final account will be $250,000 with an 80% profit split.
