Thanks for the confirmation of the order behaviour from your testing. I have however found the issue. The StatusReason states that the following error ... Status: 10 (Red Card) StatusReason: 20 The Quantity decimal places exceed the maximum allowed for the market. This occurs because I am assigning a double precision number in the Quantity field of my JSON request which is not rounded to 2 decimal places. "Quantity" = 3.500000000000001 When I round the Quantity to 2 decimal places and format as a string in the JSON request the issue is resolved. "Quantity" = "3.50" Thanks for your help on this.

Why do I receive error: "The Quantity decimal places exceed the maximum allowed for the market." on my demo account for the below new market order attempt? Is the Quantity of 0.35 too low?
