PDT for Paper Trading Account


I have a paper trading account with 100K in equity. I testing a strategy by writing a program and when I execute about 10-12 bracket orders via API, it returns the following error:

“code”: 40310000,
“message”: “trade denied due to pattern day trading protection”

I understand that one needs to have 25K in the account to comply with Pattern Day Trader (PDT) protection, but I have 100K in my paper trading account with 400K buying power and still getting flagged. Can someone please help?
