Max exposure

it would be useful, above all, to have the maximum exposure on the statements page. that is the maximum amount of money you have at stake

Over which period of time?

I come from the world of trading and I know MT4 and its backtesting function very well.
it would be interesting to know, during the day, how much the maximum exposure of money is, would help to understand how much money would be used in the bank for a long-term strategy.

you only need to memorize the MAX, so you could take the data with each update of the Wallet, if the sum of the money in play is greater than the previous maximum memorize it

You already do something similar with the MAX of P and L where you indicate your winnings and maximum loss

Yes, this is a very good idea, will take it on board.
