What Budget Manager actually does
The Budget Manager does the arithmetic between a plan and an order. Given an account size and a maximum loss per trade, it divides the risk by the distance to the stop and rounds to a valid share count.
It writes one bracket order with the entry, stop and target, and shows the loss at the stop price so the number is visible before anyone approves it.
Capabilities
