CCT Bollinger help

[upsndowns]

hi,
struggling with ninjascript generally, but at present, i'm trying to add color above 100 & below 0 of the cct bollinger indicator(period changed to 14) i dowloaded from the forum. see my attempt under "onbarupdate...drawregion" & please advise me of my errors. thanks.

Add(new Plot(Color.FromKnownColor(KnownColor.Black), PlotStyle.Line, "Output"));
Add(new Line(Color.FromKnownColor(KnownColor.Red), 100, "Upper"));
Add(new Line(Color.FromKnownColor(KnownColor.LightGreen), 0, "Lower"));
CalculateOnBarClose = false;
Overlay = false;
PriceTypeSupported = true;

protectedoverridevoid OnBarUpdate()
{
Output.Set((Close[0]+2*StdDev(Period)[0]-SMA(Period)[0])/(4*(StdDev(Period)[0]))*100);


DrawRegion("tag1", CurrentBar, 0, CCTBollinger(14).Upper, 1000000, Color.Empty, Color.LightSalmon, 2);

DrawRegion("tag1", CurrentBar, 0, CCTBollinger(14).Lower, 0, Color.Empty, Color.PaleTurquoise, 2);
}

upsndowns,

You cannot use a value like 100000 for the barsAgo starting point. Instead you want to use CurrentBar variable in there. That will get it to the very beginning of the chart.

hi josh,
i am trying to fill the regions from 100 to chart edge & from 0 to chart edge, & the "drawregion" help in nt suggests putting a high value to do this for the upper region.
when compiling, the problem seems to be with the "cctbollinger(14)upper" in :
DrawRegion("tag1", CurrentBar, 0, CCTBollinger(14).Upper, 1000000, Color.Empty, Color.LightSalmon, 2);
it doesn't recognise it..i think?
thanks.

upsndowns,

Please provide the exact error message. If you feel the plot does not exist I suggest you check that indicator again. Perhaps you mistyped the name or plot name of it.

hi josh,
i ended up painting my cct bollinger indicator background similar to 1 of the examples in "custom indicator development" in help.
it turned out better & more informative than my original idea :)
taken me 3 days adjusting my indicators to get the look i wanted more through luck than fully understanding...i'm still very fuzzy on the language.
finally (for now), are there any ninja online events that cover indicator development? thanks again.

upsndowns,

Unfortunately we currently do not have any events for indicators. We have one for Strategy Development through the Strategy Wizard though.
