I have created a strategy as per my understanding of your requirement. Please refer to the below link to learn how to write your conditions in Streak.
The above strategy will generate a trigger when the high is higher than EMA20 in the previous candle and in the current candle the high crosses above the previous day’s day.
The exit will be triggered when a daily candle closes below the Signal candle’s close value (candle where high crossed above the previous candle high) or when a candle closes below the candle prior to the signal candle, whichever is lower. I have kept the TP as 20%, you can change this as per your preference.
However, we have shared conditions based on our understanding of the above description of the strategy. You can refer to and create the same on the new platform.
