The timeliness of the contract is very important. For example, if you want to buy Bitcoin at 54,000, and then see 57,000, but it has not retreated to 54,000, it has risen to 57,000 in advance. At this time, your stop-profit target has been reached, but if it falls back again, you can't open it again, because after obtaining the liquidity of the short position, the force will be very strong, at least you can't place an order and need to observe. So if he really wants to rise, he won't give you any chance to pull back and get on the train. It will rise all the way. Only if there is no pullback before the surge is it relatively safe to get on the train.

Of course, sometimes when the support is strong and the market is volatile, he may always rebound when he encounters support. For example, the support of Ethereum 2800 in the first half of the year has been supported for 4 months. Every time it reaches 2800, it can rebound by 500 to 1,000 US dollars. Then this is a large-scale support. Once it breaks down, it will be a bottomless abyss. There is mainly a technical aspect here. For example, after breaking the large-scale support, it will normally rebound to the support quickly, and then it will not go up and continue to fall. In extreme market conditions, it will directly break down and not give you the opportunity to rebound to strong support.

But you will often encounter another situation, for example, now everyone knows that ETH2200 is the support, and then as soon as it falls to this position, you will go long or buy the bottom, and then every time ETH does rebound, you will also make money, and finally you will do this over and over again, so that you will develop a habit.

At this time, many people will say, anyway, I will go long at 2200, and the stop loss will be set at a new low, and then every time he makes money, suddenly the dog dealer really breaks the new low with a needle, knocking out your stop loss, and finally it stops falling and pulls back in the opposite direction. At this time, all the stop losses are knocked out, making many people think that it will continue to fall after breaking, so they go all-in to add positions and chase shorts, but it pulls back in the opposite direction and you short and pull the position out, making you lose money back and forth, and finally you return to zero.

This situation is very common, so the profit and loss ratio of shorting at resistance and long at support is very high, which is completely fine. If you stop loss after the price breaks, it is a normal transaction. Don't do it back and forth. It is easy to fall into a trading trap if you do it back and forth. #翻仓
