I'm not a good trader but usually, there is an analysis that I compare that shows charting and lines on which will be the next scene that we're going to see.
I have been using Relatively Strength Index RSI for a very long time which shows whether a currency is overbought or oversold, but that doesn't mean it never fail, but at least it gives me some hints of Bitcoin market in the future, sometimes I switched over to MACD which is also easy to understand. You can possibly research on these two for more better understanding, Fibonacci indicator is very complex, so I think you should stay out of that.
This is also one of those indicators that I've learned about it being oversold. @OP you can compare and collect the usual indicators that you can see on the Speculations. You'll see interesting points, charting and analyzing to support why they think it will happen.
