A small user-friendly dialog panel that dynamically calculates and displays the maximum lot size permitted on your brokerage account for different types of orders – buy, sell, pending buy, and pending sell. It is based on the available margin. It should be capable of not only calculating the max lot size on forex pairs, but on other kinds of securities as well such as commodities, crypto, and indices. The dialog can be minimized or closed from the panel itself.Â
