Hello,
I try to place an order in paper trading and I get this:
Failed to place order for UUP: Error: Request failed with status code 422
Failed to place order for TMF: Error: Request failed with status code 422
Failed to place order for TQQQ: Error: Request failed with status code 422
Failed to place order for FAS: Error: Request failed with status code 422
Order of 50 shares for GLD has been placed.
Do you know why?

What kind of order are you submitting?

If you specify money amount rather than share quantity, some tickers do not allow fractional quantities, and your money amount could result in exactly that.

HTH.
