["Vinay Gakkhar." <vgakkhar@xxxxxxxxxxx>]

In the following formulae, I want to show in place of 'AA' the percent difference between yesterday's close price with that of the day before yesterday. And in place of 'BB' I want to show the percent difference between close price of today's just previous intraday bar with that of the one just before it.

PlotShapes( IIf( AA,  shapeUpArrow, shapeNone ) , colorGreen );
PlotShapes( IIf( BB,  shapeHollowUpArrow, shapeNone ) , colorGreen );

Can anyone please tell me what to write?

Thanks,
Vinay Gakkhar
