Trendlyne’s ‘My Custom Parameters’ feature allows you to create your own parameters/metrics, by using a formula and saving it under a specific parameter name. You can then apply this parameter while creating screeners, simplifying the process. These parameters can then be used during screener creation, and be shown in your columns in screeners and watchlists, as well as under My Metrics. 

This feature saves time, ensures consistency, and helps you create and save advanced formulas without having to rewrite the same conditions.
