3 indicators to eliminate false signals

This is Matic/U.S Dollar and I'm using 3 indicators to help with eliminating false buy/sell signals.

1) MACD
2) RSI x 2 ( 25 & 100)
3) Supertrend

New to day trading crypto but these are super helpful indicators and you have to make sure the lines cross in the RSI and the MACD to have a good signal to buy or sell. In the MACD the blue line must cross the orange line to have a good signal.
