There is a lot of fluctuations and uncertainty. I look at different websites and youtube sites. Learn how to read TAs. I like Tradingview's website since it has many different voices with varying styles of trading. I just find though, if you are going to trade, you have to watch it for a while to see where the market is heading since it can rise and fall very quickly in minutes. I also just do percentages to cover a spread of prices. There is no way to predict it really. You can intelligently guess.
