I am not good with it, to be honest, but I can suggest you this site.

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.
