I'm new to Margin altogether and need some help. Here are my numbers:
Total Margin Requirements $0.00
Total Margin Equity $190.68
Adjusted SMA $205.34
Maintenance Excess $190.68
Non-Margin Purchasing Power $190.68
Margin Purchasing Power $410.68
Every time I attempt to make a trade (selling a put option), it won't let me. I'm with E*Trade.
