When looking at an altcoin chart (tradingview.com, open the bollingerband) you should attention to choose a good altcoin:
1.Altcoin has many days down continuously, but the 24 hour volume does not decrease, it's still hides the increase => Altcoin is in the accumulation phase to pump
2. Bollinger band is narrow for several days forming a small band
3. Buy altcoin only when Relative Strength Index (14) <30. (tenicals on tradingview.com)
