The Mplus trading platform does not show profit/loss for any contracts.
It just shows the list of past contracts, and the current holdings, and the last market prices of the client's holdings.
You can check under My Acc > Contract Note for your contracts from there, you can see the gain/loss of each holding based on the average purchase price vs market price of each stock.
However, one of the benefits of opening a trading account with MQ Trader includes FREE i3investor portfolio integration. This allows you to synchronize your trade data to the i3investor advanced Portfolio Management System. You can use this Portfolio Management to easily view and calculate your profit and loss. You can send your integration request to the dedicated MQ Support group we have for you on Whatsapp.
