$Invesco QQQ Trust(QQQ.US)$Tesla(TSLA.US) Comfort everyone. I think my operations were problematic during the half-month continuous loss in January. Although the amount was not large, the operations were severely distorted, so I stopped for more than half a month, just sitting here every night watching. Making records at night, reviewing during the day. Only then did I realize my operations were crap. Risk control awareness, K-line interpretation, correlation, political trends, the conversion of large and small levels, and operational strategies, personal systems, are almost all close to zero. So I strongly suggest that those who do intraday trading must write clearly before the market opens: what is the general direction, under what circumstances to buy today, what to buy, how much to buy, where to set the stop loss, why, where to set the take profit, why, and what is the personal mood at this moment. During the day, go through the market again and review whether the initial judgment and operations are consistent with the subsequent trends. Finally, the decline in QQQ this wave is the strongest since November 20, so it is likely to reach the level of 600 on December 17. You can first look at the 606 support and then 600. Don't easily bottom-fish the crown prince.
