After some simple research I found 3 indicators which are very easy to read and help opening long or short positions
1) RSI (shows if the coin/stock is oversold or overbought in a specified timeframe) 2) SuperTrend (Indicates Buy/sell signal ) 3) Backtest Single EMA cross (trend lines and buy/sell signals)
I'll update if any better indicators is found. If anyone has other good indicators please share.
