Selection Strategies, or Screening, use the Select() function.
They serve as alternatives to Screening Filters, allowing for the configuration of more complex conditionals and advanced logic for filtering.
How to Create
To create a new indicator, go to Strategy Editor inside of the Strategies menu:
In the following example, the strategy filters all assets where the 10-period RSI is greater than 70. Otherwise, it selects only the assets where the 10-period RSI is lower than 30, highlighting excessive buys and sells.
The rule can also be created through the BlockBuilder.
After the strategy is created access Screening inside the Strategies menu.
While creating a new filter, select the option Use Selection Strategy and choose the desired strategy. After that, configure the Interval and Asset List and click on Apply.
