I am a little confused by daytrading_buying_power and buying power. My account information is as below. Why the buying_power is 53617.21 but daytrading_buying_power is only 10928.028 ? How to calculate daytrading_buying_power ?
When submit an order > daytrading_bying_power, e,g, #15000, it is rejected and show no sufficient daytrading buying power. but the buying power is still > 15000, how to understand that ?
If based on my last pull of the account. Equity = 120921.79, last_maintainance_margin = 92417.982, daytrading_buying_power = 114015.23, if calculated by daytrading_buying_power = 4 * (last_equity - last_maintenance_margin). But the account shows only 17601.292
