The short position was closed at 75% at 4293, keeping 25% to continue defending, maintaining a bearish outlook, but the support level has been adjusted. The last line of defense is now 4160, so aggressive longs can build the first batch of positions at 4180, with 4150 defending the second position, holding a maximum of 50%. A stop loss at 4100, and no take profit for now. If 4150 is broken, it may continue to drop to find support level.
