Investopedia is a great start. Start with the basics.
First, study candle bars. What are they? Where did they come from? What can they really tell us beyond, high, low, opening, closing.
Next, learn some basic candle patterns. Start with easy ones. Bearish engulfing, bullish engulfing, hammer and doji. Watch videos. Take notes. Then go to tradingview(.)com, look at the past candle charts for BTC and ETH. Can you find the patterns you just learned. Once you find them, did they hold true? Did they accurately predict what happened next?
Next, learn some more candle patterns. Maybe hanging man and shooting star. Do the same thing as above.
That should take you at least a month. Study like mad.
After that, start learning basic indicators, so at least you know what they do, how they work. Start with MA and EMA. Easy. Again, watch videos, and study. Next, try MACD, and then RSI. Again, go to charts, turn on indicators, and study. Did they hold true? Did they accurately predict what they were supposed to? And how often were they true? For example, if RSI is showing oversold conditions 3x on a chart, was it right 3/3? Or was it right 2/3 or worse yet, 1/3? Again, take notes. Write things down. Make a spreadsheet if you have too. Gather research numbers. Get a feel.
When you think you've got all that down, remind yourself you don't. Then review everything again. Study more charts. Then get back to me and we can go from there.
For videos, try trading212 on youtube. Load their video channel, scroll to bottom for first videos. They have great tutorials for beginners. Very concise and to the point, unlike this long reply. Lol
