Descending Triangle Pattern is a Bearish Chart Pattern or Trend Continuation Pattern. As you can see that the price is making lower highs which means Buyers are weak and downward momentum is building. In most cases, this pattern indicates traders to make a short position. But I am Suggesting Long position here as the Bullish Harami Pattern is observed at the support zone which is a Bullish reversal Pattern.
How to trade? Enter the trade once the trend line breakout appears and retest is done. Keep Stop Loss below the Support zone. If SL gets big then try keeping SL below recent Swing low. One can Keep Target of 1:3 or near to the supply zone. OR as per your Appetite.
