$SOL SOL has been quite strong recently. I was anxious to open a short position at 203 USD and set a stop loss at 220 USD. I almost got stopped out in the past few days. Whenever I opened other coins, I would have taken profits. Damn it, it closed at the original price after returning to 203 USD yesterday. The 4-hour K-line has entered a retracement trend. Continue to pay attention to the resistance level of 210 USD. This time I will be more patient and wait until it approaches 210 USD before considering opening a short position. By then, I will take profits at the daily support level of 195 USD.
