i see the difference between the code. i am trying to plot a border
around the weekly histo that you have coded, it only does it for the
last 2 bars. am i missing something here.
here is a screenshot.
http://screencast.com/t/oXJbAruyUQP
the code that i have used is adding 2 extra lines to differentiate
the color and plot the line. here is the one giving me trouble
Plot(TimeFrameExpand( weekhist, inWeekly, expandPoint ), "",
colorBlack, styleNoTitle|styleLine | styleThick | styleNoLabel );
the entire code is below for reference.
_SECTION_BEGIN("Weekly MACD");
TimeFrameSet( inWeekly );
intname = Interval( 2 );
weekmacd = MACD( sh = Param("Short", 12, 1 ), lg = Param( "Long", 26,
1 ) );
weeksig = Signal( sh, Lg, Param("Signal", 9, 1 ) );
weekhist = weekmacd - weeksig;
plotColor=IIf(weekhist > 0,colorGreen,colorRed);
TimeFrameRestore();
Plot( TimeFrameExpand( weekmacd, inWeekly ), "MACD", colorRed );
Plot( TimeFrameExpand( weeksig, inWeekly ), "Signal", colorBlue );
Plot( TimeFrameExpand( weekhist, inWeekly, expandPoint ), "Hist",
TimeFrameExpand( plotColor, inWeekly, expandPoint ),styleHistogram );
Plot(TimeFrameExpand( weekhist, inWeekly, expandPoint ), "",
colorBlack, styleNoTitle|styleLine | styleThick | styleNoLabel );
PlotGrid(0, colorBlack);
if( ParamToggle("Custom Title", "No|Yes", 0 ) ) // custom title
{
Title = Name() + " " + intname + " " + Date() + " MACD" +
_PARAM_VALUES();
}
_SECTION_END();
