Ah. Trading view doesn't have the green and red lines... it just has lines above or below a line... which I've never really paid attention to before. I'm constantly flicking between the different time frames to try and read the trends...
So a buying cycle is like a flurry of buy trades? Is a buy/sell cycle where a green stick turns to a red stick?
