Bearish traders, think about it. Suppose you are short now, and it pumps up 30 points, trapping you at 3470. You hesitate to cut losses, thinking about a stop loss at 3485. When it really hits 70, you can't bear to lose at 85, so you move it to 35. As a result, a long wick candle shoots directly above 3530. Now you're tied up. Think about it, isn't it always like this? Afraid of heights and not daring to chase rising prices, we just hold a short position and rest, eating well and sleeping well, waiting a couple of days before making a move. If you really can't hold on, take some time to understand the contract cooling-off period. If you still can't resist, go trade altcoins with a small position.
