Question about AccountProfit()

I'm testing AccountProfit vs. AccountMargin as a way of handling trade exits. My question is does AccountProfit only use all open trades to calculate P/L or does it use closed trades as well?

I know OrderProfit uses only open trades but it's only for EACH individual open order's P/L.

I *think* that AccountProfit adds and totals all OPEN trades P/L only and does not include closed trades. Or am I mistaken here. I couldn't find any clear documentation regarding this. Anyone know for sure?

AccountProfit() is the P/L of the current opened positions.

OrderProfit() is the P/L of a specific order selected under MODE_TRADES (opened position) or MODE_HISTORY (closed position).

That's what I was hoping for. Thanks.
