always check the price action when the second second low is breaking out from the last resistance. when the RSI didn't form a divergence, don't buy. (not a financial advice)
It's hard for me to analyze where the buying/selling signal is just by looking on the price action, that's why i use some technical indicators.
What I love about RSI it it increases my win rate. But still there's still a lot of false signal happening.
One is the RSI can go at 30 or 25 level at a long period of time, don't buy just because it goes on that level.
