Your Unrealized P&L can change your Available Balance while your positions remain open.
-If your open positions are making a profit, your Available Balance may increase.
-If your open positions are making a loss, your Available Balance may decrease.
Example:
If your Available Balance is $700 and your open positions have an Unrealized Profit of $50, your Available Balance may increase to $750.
If instead your open positions have an Unrealized Loss of $50, your Available Balance may decrease to $650.
Because market prices are constantly changing, your Unrealized P&L and Available Balance can also change while your positions are open.
