If you want to buy, you have to wait for the buying opportunity when the minute line rises. Generally, you should buy 1 minute after the callback or when the trading volume of the time-sharing chart begins to shrink. Stop loss is set at the following points, otherwise you have to run if you feel wrong! Because even if shrinking means that the high probability of rising is not necessarily rising, it is possible to continue to increase slightly and continue to bottom out. At this time, if the previous entry position is not ideal, strictly speaking, it is necessary to stop the loss, and then enter the market after determining the bottom! If you have a strong sense of certainty, don't stop loss for the time being and continue to stop loss downwards, and the market will be relatively enlarged. Of course, if this is the bottom and it rebounds upwards, you must hold the order, because if you can't hold the order, you will earn less, and it will be difficult to achieve the overall profit in the big cycle in the future when the loss or single stop loss is large!
