Crypto Indicators

Hi!

I'm working on a project where buying and selling goes automatically from a script, now everything is setup and tried a couple indicators ( BUY: MACD 12 26 close 9 EMA EMA and SELL: RSI 14 SMA 3 > 68 or -3% profit ).

The BUY indicator is working perfect.

I was just curious if someone knew better indicators to BUY/SELL to experiment with?

Thanks!
