can i use my personal broker to mirror my prop trades for extra size

[itsliam]

idea: take the same trades on my personal account that i take on my funded prop account, to stack a bit more real size on my best setups. is this sensible risk-stacking or am i quietly doubling my risk and about to learn a painful lesson?

youre doubling your directional risk, full stop. mirroring means a single bad trade now hits both your funded account and your real capital at once. the prop fee is your only downside on the prop side, but your personal account is real money. people frame this as 'extra size on my best setups' but it really means your worst day is now twice as bad in the place that actually hurts.

the whole point of using a prop is to risk their capital instead of yours. mirroring on your personal account undoes the only reason to be there. you took the safer vehicle and bolted the dangerous one back on.

[Jason]

both right. if you genuinely have an edge and want more real size, the cleaner path is to size your personal account properly on its own risk terms, not to chain it to the props trades. mirroring correlates the two perfectly, which is the opposite of sensible risk management. independent sizing beats blind doubling.

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.
