I am not good with it, to be honest, but I can suggest you this site.
https://www.tradeciety.com/the-basics-of-chart-reading/I asked my friend about the candles they are talking about in the past since I am so left out when they talk about the price charts in the past. At that time we usually hang out and they would have this conversation where they would talk about the movements at the chart and they have this name for that. They just laughed at me and suggested this site to read for a start. I have some photos of the patterns of the candlestick chart, the same as Renko charts and point and figure charts.
It is important to learn as much as we can about that subject, even if you do not want to be a trader and you are an investor you can still use the charts to know the overall direction of the market and know if you are going to obtain profits or if you are going to face some difficult months and you will need to prepare yourself mentally for that, so even if you are an investor you can easily see that you can get some important benefits from learning this subject.
