Trading review ..... On December 13th, this long position was not well executed and the direction judgment was incorrect. It was damaged on the evening of the 14th (the first principle of short-term trading is never to carry orders). On December 14th, at 19:00 in the evening, the hour k was inserted downwards. At this time, the indicators did not give a clear signal, but I impulsively continued to enter the market and open more. Then it was damaged again on December 15th. Through a review, it can be seen that this order was completely illogical and lacked logical thinking. It was purely a competition between oneself and others, as if trying to "regain face" for the multiple orders on December 13th. This is a foolish and dangerous idea. (Figure 1) After the loss of this order, I forced myself to remain calm and not continue trading when my emotions were irrational. Therefore, I did not catch this wave of decline from the evening of the 15th to the early morning of the 16th because I wanted to regain the rhythm of the short-term market. After the cooling off period, when seeing multiple trading signals - mainly based on the extreme deviation of the trend line and the return to the median, combined with the "overbought/oversold" signal, especially when there is a sudden increase in trading volume - find opportunities to intervene and make short long/short positions with high certainty. (Figure 2) The next 5 orders were all profitable, and the last order was opened at 85150 today, with a current floating profit of 12%. I will not preset the profit amount or proportion for each opening, only based on indicator signals, and will level off at the point. Unfortunately, yesterday (18th) at 22:00, there was a short order opened at 89166, when we saw oversold signals and trend correction. But at 23:00, the K-pin was inserted upwards, breaking the deviation of the indicator. I'm worried that if I continue to pull the disk in the second half of the night, it will be damaged and it will be flat, basically flat in and flat out. In fact, as long as I keep an eye on the market for one hour and wait for the candlestick at 24:00 to come out, and the indicator recovers and deviates from the repair, I should not be flat, and I can also eat the profit that fell to 8.5w later. I woke up in the morning and seamlessly connected with the oversold signal, turning my back to open more. Of course, there aren't so many 'ifs' in trading, all there is is is constant summarization, reflection, and improvement. Trading is a combination of mentality, technology, emotion, and repeated refinement. After the fact review is like a 'magic mirror', through which you can see the most authentic version of yourself at that moment. Admitting mistakes, correcting mistakes, correcting mistakes - it is important to promptly discover whether the beast in your heart has been controlled by emotions! If so, stop immediately. I only do BTC in the short term, with low leverage, and set stop loss levels for each order. The purpose is to cultivate a sense of empathy in practical situations, learn to control emotions, and strictly implement strategies. A small level can transmit to a large level, and the logic that can be implemented at a small level can also be applied to a large level, but it takes longer and requires more patience.
