//@version=5
//-----------------------------------------------------------------
//This simple strategy base on RSI, EMA, Bollinger Bands to get Buy and Sell Signal with detail as below:
//-----------------------------------------------------------------
//1.Define Oscillator Line
//+ Oscillator Line is smoothed by ema(28) of RSI(14) on H1 Timeframe
//2.Define Overbought and Oversold
//+ Apply Bollinger Bands BB(80,3) on Oscillator Line and calculate %b
//+ Overbought Zone marked above level 0.8
//+ Oversold Zone marked below level 0.2
//3.Buy Signal
//+ Entry Long Positon when %b crossover Point of Entry Long
//+ Deafault Point of Entry Long is 0.2
//+ Buy signal marked by Green dot
//4.Sell Signal
//+ Entry Short Position when %b crossunder Point of Entry Short
//+ Deafault Point of Entry Short is 0.8
//+ Sell signal marked by Red dot
//5.Exit Signal
//+ Exit Position (both Long and Short) when %b go into Overbought Zone or Oversold Zone
//+ Exit signal marked by Yellow dot
//-----------------------------------------------------------------
