Indicator plotting O-H-L-C with lines between.

[Johnny]

Hi,

I wish to create a simple indicator that plots the following on an intraday chart (1-minute primarily, but would be nice if it could work on 5-minute as well) for each session:

Open

High

Low

Close

With lines between these values.

I'm attaching a sample picture of what I mean.

Could anyone help me accomplish this?

Thanks in advance.

Hello Johnny,

To find the highest and lowest bar of a session the HighestBar() and LowestBar() tools can be used with Bars.BarsSinceNewTradingDay.
HighestBar() - http://ninjatrader.com/support/helpG...highestbar.htm
LowestBar() - http://ninjatrader.com/support/helpG.../lowestbar.htm
Bars.BarsSinceNewTradingDay - http://ninjatrader.com/support/helpG...tradingday.htm
For example:

Print(Time[HighestBar(High, Bars.BarsSinceNewTradingDay)]);

This would print the time of the highest bar in that session as HighestBar returns a barsAgo value used for indexes or for calls to drawing tools.

Time - http://ninjatrader.com/support/helpG...eries_time.htm
Open - http://ninjatrader.com/support/helpG...en-us/open.htm
High - http://ninjatrader.com/support/helpG...en-us/high.htm
Low - http://ninjatrader.com/support/helpG.../en-us/low.htm
Close - http://ninjatrader.com/support/helpG...n-us/close.htm

A dot could be drawn using that time, or could use the bar number.

Once you have the lowest low and highest high, you would need to pick which of these to draw the line from the open. Which ever has a greater bars ago value would come first.
The session open barsAgo value would be Bars.BarsSinceNewTradingDay. The close of that session would be the CurrentBar.

To ensure there is a new set of lines drawn for each session (and only one set of each of the 3 lines), the tagName will need to be reused on each bar and then changed when a new session starts.
I would recommend using a variable that is incremented when Bars.IsFirstBarOfSession is true and concatenating this with an identifying string.
