Implementation
' Get the opening prices of the symbol, indexed by bar index. Define open() As Number = BarOpen(_symbolIndex, barIndex, 2) ' Get the highest prices of the symbol, indexed by bar index. Define high() As Number = BarHigh(_symbolIndex, barIndex, 2) ' Get the lowest prices of the symbol, indexed by bar index. Define low() As Number = BarLow(_symbolIndex, barIndex, 2) ' Get the closing prices of the symbol, indexed by bar index. Define close() As Number = BarClose(_symbolIndex, barIndex, 2) ' Check whether the first candlestick matches. If (open(1) < close(1) And _ 100 * (close(1) - open(1)) / open(1) > _minCandleSize) Then ' Check whether the second candlestick matches. If (high(1) < low(0) And _ MathAbs(100 * (open(0) - close(0)) / open(0)) < _maxDojiBodySize And _ low(0) = open(0)) Then Return 2 End If End If Return 0
