To be able to see the right signals you need to understand the technical analysis. In 2 words it is difficult to tell about it. I took courses with a professional trader. That really helped me.
As long as you have enough knowledge on crypto trading,then recognizing correct trading signals is not that hard.Once the market is in long dump like we are facing at the moment,i believe it is not a good timing to trade because you will only end up making a little profit or worst,losing in the end.So focus more on the price chart and the daily movement of the crypto and not in fuds because it will only make you lose your investments.
