Bloomberg is being â– â– â– â– in providing recent indicative prices, this is definitely a thing (I have a whole thread on it)
When you place an order T212 calls Interactive Brokers via it’s API. It’s then up to IB to place the order, and then pass back the response to T212 on placing/filling/rejecting
So it’s most likely IB, or the reject message coming back to them. So it’s a case of sit tight whilst @David@Rumen etc investigate that
