Hi all!

I'm trying to create a simple (I thought it would be simple!) study using sc.GetStudyArrayUsingID() to overlay onto my volume by price study. Maybe I shouldn't be using this function?

I am wanting to draw a horizontal line based on a calculation involving either the high or low of the day and the POC.

I would like to add the POC to the low of the day value if the POC is above the mid point of the day (another line that I have on the chart)

or

If the POC is below the mid point of the day I would like the POC subtracted from the high of the day.

I hope this makes sense!

Any help greatly appreciated.

Thanks Gordon

busy trading, but this code shows examples of how to reference other studies to perform secondary work on them

 

Code

// The top of every source code file must include this line // SM_CCI_Alerts.cpp #include "sierrachart.h" #include <math.h> /***************************************************************************** For reference, you want to look at the Advanced Custom Study Interface and Language documentation on the Sierra Chart website. *****************************************************************************/ // This line is required. // Change the text within the quote marks to what you want to name // your group of custom studies.

Thanks hobart,

Appreciate the reply during the trading day.
I still have a fair bit of study to do because that is still making very little sense to me! lol

Code

sc.CCI( sc.BaseDataIn[SC_HLC], // This is the input array or source data -- this is using the Last or Close from each bar sc.Subgraph[2], // This designates your output array (subgraph/plot) -- this is using Subgraph 1 sc.Index, // This parameter is always sc.CurrentIndex 50, 0.015); // This is the length for the CCI and float multiplier, which is from Input 0 if (sc.Subgraph[2][sc.Index] >= 100) sc.SetAlert(7); // all CCI's in pos. zoom

In this snippit, i call the built in study CCI, store the result in sc.Subgraph[2], then reference if its current bar value (sc.index) is greater than 100.

Great, Thanks again for the information Hobart.

I am slowly getting there, and all of this helps.
