There is no direct sign we can only see the volume start to increase rapidly and the market is slowly change from red into green. I believe that no one can predict the price and all speculations always follow when the market is recovering the people speculate that the market start to be bullish but when the price fall people always say a bad comment and speculate that bear market is happening. I am here since year 2017 when bitcoin is rising and bear market happens on 2018 to 2020 but i don't really saw persons  that can predict the exact price.
