Looking at the four-hour chart of ZEC, the price has been oscillating within the 420-380 range, with particularly strong selling pressure near 420. From a technical perspective, the RSI has entered the overbought zone, and although the KDJ is still rising, it is about to top out. This combination of signals generally indicates a potential pullback.

In simple terms, it is more appropriate to short around the 420-430 level, provided that strict stop-losses are set. The target below is around 390-380, where support is relatively clear.

This is just a personal idea; everyone's risk tolerance is different. For reference only, be sure to control your position size and risk when operating.
