QuantNomad - Simple Custom Screener in PineScript

Quite often I need to run screeners with the custom condition, but unfortunately, in TradingView it's impossible.
I created an example script to show how you can create a simple custom screener in Pine Script on your own.
It's not very good, it requires some manual adjustments, it can be improved in some ways, but I think it might work for some tasks.
What do you think? Do you have a better way to implement custom screeners in TradingView?

To run your own conditions you need to implement them in:

customFunc() function and for every ticker you want to include in your search add 2 lines like these with newly defined variable:

s1 = security('BTCUSD', '1', customFunc())

and

scr_label := s1 ? scr_label + 'BTCUSD\n' : scr_label

I'm not sure that it will work well for more than a few dozen tickers.
But I hope it will be helpful for you.

And remember:
Past performance does not guarantee future results.
