1) I have seen some course about technical analysis, they explain those charts where it would have worked before, saying support brake resistance 'sell'
resistance brake support 'buy' and those chart patterns
2) when we must not use Technical analysis
in simple, my question is , does technical analysis work every time and can we predict every move using technical analysis or times when we should not predict price using technical analysis
Technical analysis is not 100% effective way for us to get profit in trading business whether crypto, bitcoin or fiat.
Although, there are some technical analysis would give you profit if you do the right things for it.
