So I bought some SPY minute data from Firstdata and did some analyst after loading it into SQL server.
I discovered that somewhere around 90% of the time I found that from 2 hours after market open to close, the range didn’t expand above 3 dollars historically in either direction.
I thought I’ll just sell condors and cover the range on the expiration day. However, the last two times I tried this, I would have closed in the money, but the brokerage closed my positions.
Because risk or whatever.
Do all brokers do this or is that just a Robinhood thing?
I saw someone post something similar about TD Ameritrade the other day.
(I wasn’t selling naked, I don’t know what risk they are talking about.)
