$ETH If there are open short positions, one should be very concerned that this current position is already at the line of life. Can the line of life hold? If it breaks, shorts can continue to profit; if it holds, shorts will want to exit, right? And if the 15-minute candle breaks the support of the line of life, it is not determined only by the 15 minutes, but by what the 30 minutes are doing. If the 30 minutes are currently in a high position and want to return to the position of the line of life, then the 15-minute line of life will not hold! You can check where the 30-minute candle is currently positioned. You can also judge if this support will be effective!
