A customer who is not in aggregation and who comes into the day with no overnight positions has a much smaller likelihood of generating a DT call. One way to cause a DT call is to day trade using profits.
A customer comes into the day with $25,000 of starting DTBP and no positions.
Trade 1 (8:45 a.m.)—BTO 100 ZZZ Feb 450 calls $2.00 ($20,000)
Trade 2 (11:30 a.m.)—STC 100 ZZZ Feb 450 calls $3.00.
Selling Put Credit Spreads for Income On Robinhood (Part 1.)
Profit of $10,000. Option BP increases to $35,000.
Trade 3 (1:30 p.m.)—BTO 200 XYZ March 60 calls $1.50 ($30,000)
Trade 4 (2:45 p.m.)—STC 200 XYZ March 60 calls $1.50
The customer’s highest open position in requirements is Trade 3, when he spends $30,000. This amount, partially made by using intraday profits from his original day trade, exceeds his starting DTBP by $5,000, and a DT call will be issued to the customer for this amount.
