1. First, investors need to choose a currency pair with relatively high volatility. Here, we recommend a currency pair dominated by the Japanese yen, because as a safe-haven currency, the Japanese yen performs best.

2. When the market opens in the new week, first check whether there is a gap in the K-line chart. The gap should be at least five times the average spread of the relevant currency pairs, otherwise it cannot be regarded as a real signal.

3. If the opening price on Monday is lower than the closing price on Friday (the time can be adjusted according to the opening price and closing price of the region), then the gap is negative, and investors should establish long positions at this time; If the opening price is higher than the closing price and the gap is positive, a short position should be established.

4. In the foreign exchange gap trading strategy, stop loss or take profit setting is not recommended (but in other trading strategies, stop loss and take profit are still necessary). In addition, it should be noted that investors need to close their established positions before the end of trading hours this week.
