if you still want personal exposure alongside the prop, treat the personal account as its own book with its own risk-per-trade limit, and accept that on shared setups your total exposure is the sum. the mistake isnt trading both, its pretending the combined risk is the per-account number when its actually double. size with eyes open or dont stack at all.
logged both accounts for two weeks and the prop really is a point worse on average but my edge has the room, so im staying. feels good to decide on data instead of paranoia.
practical takeaway: dont let the backend broker alone make or break the decision, but do treat a weak one as a reason to take payouts promptly and not leave large earned balances sitting in the account. withdraw on schedule and your exposure to the underlying broker stays small regardless of its quality.
