murthysuresh,

If you were writing to me, the answer is I don't know. I wrote to 
support and showed them what I was trying to do, using a chart from 
another program as an example, and they sent me back a PlotOHLC 
command with a zero in the 3rd argument.

Perhaps they could answer your question. Here is the program I use 
the PlotOHLC in:

///////////////////////////////////////////////////////////////
// Program : DPO With shading
// By      : Bill Halliday
// Date    : 2006-12-05
// From    : A customized version of the 'DPO - Detrended Price 
//           Oscillator' Indicator found in:
//           Program Files/AmiBroker/Formulas/Indicators that 
//           displays a shaded plot using styleCloud
//
// Initial Alterations:
//
//       1) This documentation.
//       2) Printf statement.
//       3) Changed the Plot to include shading.
//
// Revision: 2006-12-07
//
//        Moved the Interpretation commentary to a "Status" 
//        'if block' AND added line feeds to the Interpretation 
//        printf for display clarity.


// Define the DPO function

function DetrendedPriceOsc( Periods ) 
{ 
return C - Ref( MA( C, Periods ), -( 1 + Periods/2 ) ); 
} 

// Start of program execution

// Call the dpo function

dpo = DetrendedPriceOsc( Param("Periods", 20, 1, 480 ) ); 

//Plot the DPO Indicator

PlotOHLC( dpo, dpo, 0,dpo ,  _DEFAULT_NAME(), colorLime, 
styleCloud ); 

// Start Revision: 2006-12-07
if( Status("action") == actionCommentary ) 
{ 
// this printf prints information into the Interpretation Window
printf ( Interval(2) + " " + Name()+"("+FullName()+"):\n\n" + 
         "High " + H + ",\nLow " + L + ",\nClose " + C + ", \n\n" +
         "dpo: " + DetrendedPriceOsc( Param("Periods", 20, 1, 
100 ) ));
}
// End Revision: 2006-12-07
