Method 1: Find the important resistance or support area in the near future. When judging the direction, such as buying up. At this time, you can find the corresponding support level as the reference price of the entry point. If you reach this support level and fail to break through, you can buy here, otherwise you can look around the next support level. Method 2: Wait for the short-term MACD deviation. The short-term deviation referred to here is generally the MACD deviation in the 5-minute or 15-minute K-line chart. When we want to buy, we should pay close attention to the bottom deviation of MACD in short-term charts during callback. When we deviate from the bottom, it should be a relatively low point, and buying near this point is a suitable opportunity to enter. Method 3, near the tangent position. This situation is that the graph goes out of the breakthrough form, and after the exchange rate breaks, it returns to the test near the breakthrough tangent. At this time, a breakthrough along the tangent will be a good opportunity to enter the market, and at the same time, a stop loss will be set on the other side of the tangent to avoid a false breakthrough in the exchange rate.
