Can someone share a sample strategy with Supertrend and MACD conditions so that I can get a gist of how to write the conditions properly?
You can use the CTB feature of Streak to do this. Simply plot the indicators on the chart and click on the Streak logo on the top right-hand side of the screen and a strategy will be created automatically with the indicators added to the charts.
I have created a strategy with Supertrend and MACD indicators using the CTB feature. Click on the below link to view the strategy conditions.
Refer to the following link to learn about the CTB function in detail - Chart To Backtest - Streak Help
Hope this helps.
