Why did I get a warning message stating "Market Order was Repriced"?

It is against regulatory rules to trade with your own orders. If you currently have a limit order working and you place a MKT order for the same product on the other side of the market, you will receive this warning as it is possible those two orders could trade with one another. To avoid this, use limit orders with specified prices so your open Buy and Sell orders will not cross.
