This is a chart intended to help spot and predict potential trends in BTC. You use the chart by looking at the 30 minute view. You'll want to see if the chart is trending up or trending down by where the lines go based on the intersections. Once you figure it out go to 5 min and then redo your last steps and figure a good intersection to buy and sell the next.
52000 is very strong support and demand, more continuation to the downside is very possible, but me personally I will not join, too risky for me, you are already in?
