Although I rarely use indicators today, mostly relying on price action, one indicator I have always found to be fairly reliable in trending markets is MACD. There is plenty of literature on Tradingview and any other TA platform, I won't go into details here. If you're just starting out on your trading journey, take a look at MACD and see how, if at all in can become a tool in your arsenal. As an example, the recent downtrend we've seen in BTC could have been spotted well ahead of the recent drop as seen here. Default settings generally work just fine, however I find that replacing those with 8, 21, 5 reduces the lag and reduces unnecessary noise.
