Available funds(AEE) are used to determine whether new positions may be opened. Opening a position refers to trading activity such as buying long or selling short. Please note that available funds is not the same as available cash. It is calculated using indicators such as total assets, options holdings market value, locked funds, and initial margin. When the available funds are greater than 0, it means the account may open new positions worth up to 4x the available funds.
Securities Segment：AEE = ELV - Initial Margin (IM) - locked EE
Futures Segment：AEE = NLV - IM - locked EE
ELV = Equity with Loan Value, summation of the assets available in securities and Funds segment;
*For cash accounts, ELV = security segment cash balance + fund segment cash balance
*For margin accounts, ELV = security segment cash balance + fund segment cash balance + total market value of securities - total market value of options + total market value of fund
NLV = Net Liquidity Value, summation of the assets available in futures segment, Net Liquidation Value = Net Liquidation Cash
