Hi,
  This code drawing a trend line. 
  y0=LastValue(Trough(L,5,2)); 
y1=LastValue(Trough(L,5,1)); 
x0=BarCount - 1 - LastValue(TroghBars(L,5,2)); 
x1=BarCount - 1 - LastValue(TroughBars(L,5,1)); 
Line = LineArray( x0, y0, x1, y1, 1 ); 
lot(C, 
  "C", colorWhite, styleCandle); 
Plot( Line, "Trend line", colorBlue ); 
  How can I draw the line for the 
  peaks.
  Regards,
