1, gap: after the stock price is affected by bullish or bearish, it jumps up and down greatly. When the stock price rises under the influence of bulls, the opening price or lowest price of the exchange on that day is higher than the closing price of the previous day by more than two reporting units, which is called "gap". When the stock price falls, the opening price or the highest price of the day is lower than the closing price of the previous day by more than two reporting units, which is called "jumping down". Or in a day's trading, it rises or falls by more than one reporting unit. Gaps usually appear before the beginning or end of a sharp change in stock prices.

2. Calculation of gap price: When you continue to hold last week's order until it opens next Monday, you miss your stop loss point and don't open the position until you cross your stop loss point. The system will not close the position according to your stop loss, but close the position at the opening price.

Similarly, if the gap skips your take profit position, the take profit price will be calculated according to the opening price of the second week.
