My paper account had a day trading buying power of $73,584.37 and I submitted a limit buy order with a quantity of 1460 at a limit price of $16.07. I believe the order value is $23,462.20 (1460 x 16.07) which is less than my buying power of $73,584.37 but I received an error (APIError: insufficient buying power). At the time I submitted this order, I also had two unfilled limit buy orders with a similar order value.
Does anyone know why I’m getting this error?
