This strategy allows you to back test longing or shorting or do nothing during time increments of 30 minutes for various days of the week. For example if you want to see if every Saturday if Bitcoin dropped in value from 1600-7000 UTC, this script will allow you to test that.
Make sure you are in the 30 minute time frame while viewing the performance and trade history.
Example how to set the time range window to be backtested for both entries and exits. Additional examples are also included showing how to set the date range and toggle plot visibility.
By incorporating this code with your own strategy's logic, it will allow you to backtest various time windows.
