$ZEC 1. Trend Analysis: The price is below the middle band of the Bollinger Bands (257.35), indicating a bearish short-term trend. The MACD has crossed below and the histogram is negative, while the KDJ (K:31.0) is in a weak area, showing that the bears are dominant.

2. Long and Short: Short when a rebound approaches the middle band.

3. Entry Point: Enter short positions when the price rebounds to the 257-260 range and faces resistance.

4. Take Profit Target: Look for the lower band of the Bollinger Bands around 215.4.

5. Stop Loss Point: Set above the middle band at 265.

(Current price 253.52 is close to the middle band resistance; if it breaks below the previous low of 239.35 with volume, further downside potential will open up.)
