access prior close in volcandle bar type indi

[nkhoi]

no matter what I tried I can't seem to get correct Close value of the prior vol bar so I can't color the current vol bar correctly.
================

...
double dblBarwidth;
//Cory add prevClose
double prevClose = 0;

for (int idx = fromIdx; idx <= toIdx; idx++)
{
//calc dynamic bar width
dblBarwidth = k * bars.GetVolume(idx) + m;
barWidth = (int)(Math.Round(dblBarwidth, 0));

barColor = chartControl.GetBarColor(bars, idx);
// barWidth = GetBarPaintWidth(barWidthValue);
closeValue = bars.GetClose(idx);
close = chartControl.GetYByValue(bars, closeValue);
high = chartControl.GetYByValue(bars, bars.GetHigh(idx));
low = chartControl.GetYByValue(bars, bars.GetLow(idx));
openValue = bars.GetOpen(idx);
open = chartControl.GetYByValue(bars, openValue);
x = chartControl.GetXByBarIdx(bars, idx);

//Cory load prevClose when idx < toIdx
if (idx > fromIdx && idx < toIdx) {
prevClose = close; }

......

//Cory -set color for doji bar
if (open == close && prevClose > 0 )
{
if (close < prevClose) {
Pen2.Color = Color.Red;}

if (close >= prevClose) {
Pen2.Color = Color.Green; }
}


if (high < Math.Min(open, close))
graphics.DrawLine(Pen2, x, high,x,Math.Min(open, close));
if (low > Math.Max(open, close))
graphics.DrawLine(Pen2, x, low, x,Math.Max(open, close));
......

Hello nkhoi,

Thanks for your note.

Is there any particular reason you are accessing the open, high, low, close by using ChartControl?

This method is unsupported.

The supported method of accessing the previous bars open, high, low, close is through the dataseries created for each of these.

For example to compare the current bars close to the previous bars close use:
Close[0] < Close[1]

or for the high use:
High[0] < High[1]

Below is a link to the help guide on Close. (High, Open, Low will all be used in the same manner).

I look forward to your reply.

This is a new bar type, bar width expanse/shrink based on volume. This is how the original author coded to get open, close for his new bar type. I am trying to obtain the previous bar close using his method but not too successful.

Hello nkhoi,

Thank you for your reply.

Unfortunately, we cannot provide support for creating custom bar types. However, I will keep this thread open so that others may offer you replies.

I recommend that you post this inquiry in the unsupported thread as well.
