Unfilled limit orders may occur as a result of the spread (difference between the bid/ask) and/or insufficient liquidity (market depth) at your limit order price. Our platform does not support partial fills, meaning that if your order can't be filled for the full amount at your limit order price, it will not be filled at all. To remedy this, we recommend splitting up your limit orders and/or checking the depth of market tool in our Breakout Terminal to see the available liquidity at a given price level.
