Ethereum trend has several important reference points in the past few days. For the January 17th rally, you can watch around 3236 (1% position). If it pulls back, consider adding to your position at 3203 (increase to 2%). The 3179 range is a relatively ideal exit point, with a 4-point trailing stop to protect your position. Conversely, for the January 16th decline, the resistance above is at 3349 (1% position). If it breaks above, consider adding to your position at 3383 (another 2%). If it continues to push higher to 3407, it might be time to take profits, with a 4-point trailing stop as well. This strategy uses layered position building and dynamic stop-losses to manage risk. The key is to strictly follow the plan and not to change it impulsively due to market fluctuations.
