In the pure contract dry goods shared today, I have always emphasized that the contract should be made at a larger level, that is, in order to effectively filter out some false signals, including the information side. We come to this market to make money, not to look for excitement. Trading on the left side, the entry signal is early, but the stop loss will be played frequently. It will also cause the anxiety of carrying the order after the order is opened, I don't know if it is to the end, and I don't know if it has reached the top, today we will give an example, for example, this time it fell 74500, I have been emphasizing that the callback saw the first yang line of the four-hour yang line 75000-77900. Come back and post that the pullback near 75800 is open long, so the question is, is our stop loss very clear, 100 points below 74500, delay this rebound to 83600 is expected there? But our risk is almost avoided. And today, the four-hour yin line appeared, and then the next four-hour actual fall below the four-hour bottom of 83080 to confirm the four-hour pullback, afraid of falling short is to fall below half of the position, go up to add positions. Stop loss before the high, there is a problem here, that is, below 83080 to allow a rebound, or the four-hour fast support 82500 is allowed to rebound, so the logic of opening a single here is, below 83080, the callback is expected to be confirmed, and the rebound high point enters the short, this position is in the 80100-84360 range, the short position is about to open a position near 83900, and the stop loss is 84501 needs a few hundred points. Another order opening logic in the next four hours of operation, the 15-minute top parting, or the hourly line top parting, is a short order entry opportunity! The daily line confirms the trend, the four-hour confirms the long-short conversion, and the hourly line and the 15-minute line look for entry points! Another in the rapid rise and fall of the market, it needs a sense of disk, as well as the ability to judge support and pressure! There is also a dry goods, the law of magnets, no matter how far any level deviates from the middle rail, the greater the expectation of getting closer to the middle rail again! That is, the moving average of 21, the farther away from the moving average, the greater the possibility of the moving average looking for support or pressure again. Regardless of the oscillation, the trend! Seriously stated, four hours will also give false signals, not a panacea. If there are 10,000 points in another big downtrend, there may be 2-3 four-hour positive lines, then it takes experience, and there will be false signals on the daily and weekly lines, not to mention the four hours, but it is still relatively stable! A personal diary does not constitute any investment advice! If you don't like it, don't spray!
