When the market price fluctuates violently or the market liquidity is too low, there may be price gaps and spread expansion, resulting in the market price directly skipping the limit price. At this time, the pending order, take profit order or stop loss order will be executed at the first price that appears and can be executed after the market skips the order price. Note: The final dealing price may be different from the price required by the limit order itself, which may lead to greater profits(The price after the gap is better than the price preset) or greater losses(The price after the gap is worse than the price preset by the investor). Therefore, investors should understand that returns and risks are two-way and equal.
