In TradingView > Indicators, under Community Scripts there's "Invite-only Script" which is non-public indicators. Does that hinder the use of Anny trading bot?
For example: I set the condition is "When X indicator has buy signal -> Bot place buy order" and vice versa for sell order

not a word here?

When it comes to TradingView bots, thru the webhook solution you can integrate any indicator/pine script that is available in your account. Creating a TradingView bot enables you to open positions, close positions or distribute the signal to your community.
It's important to disclaim that community scripts are not available in the smart trading terminal (our TradingView integration to view charts and open smart positions manually).
