Most effective indicators?

What are the top effective combinators for good entry and exits with little loss and that can give good ROI.

I know that there are definitely no “best” indicators for all markets, but you could as well share how you have been going along with your trades and how we can learn from it easily. I am open to suggestions and corrections as well, I don’t want to use too much, because I have found too much of them on Tradingview already.
