Net value = balance+floating profit and loss. Account funds only calculate the total amount after all your closed orders, and the net value is to calculate the total amount of all your closed orders and open orders. The difference is that the former does not calculate the open position, while the latter calculates the open position.

The account balance is actually increased by the margin you used, excluding floating gains and losses. Some platforms of margin balance remain unchanged, and some platforms are changeable. This is the question of whether the floating profit and loss is counted. In fact, the difference is the floating profit and loss and the money that takes up the deposit.
