Wicks/tails on Linebreak charts

[arbuthnot]

Hi everyone

This question arises from thread 'Linebreak indicators' started by Labdog at:

http://www.ninjatrader.com/support/forum/showthread.php?p=401224#post401224

We've been helping each other out in this thread: Labdog's the Linebreak expert and I know a bit about coding.

Labdog has asked a great question here:

Linebreak bars show only a part of the actual price they reach. Could tails be added showing where the price really went for that bar? Could these lines be also formed on the live bar showing just like a time frame bar would leave tails as it forms?

Please see Labdog's image attached.

The only way I can think of doing this is to add a tick chart in a second panel, find the time of the open and close of the previous Linebreak bar and then find the max/min of the tick chart in this period. This would also be quite CPU intensive. (Obviously, the same logic would apply to Renko charts, etc.)

This is really pushing at the limits of what I can do myself. Is there a way of avoiding loading an auxiliary tick chart? Is there a direct way of achieving this?.

Any suggestions on how to achieve this will be much appreciated.

LineBreak is a kind of chart. Copy the class file and modify as necessary, much in the same manner as "UniRenko" and all the other shadow-showing "Renko" bar types were created by referencing the shipping Renko bar type.

Hello arbuthnot,

Thank you for your post.

Aside from adding in the tick series, you could create your own custom bar type but this requires unsupported code for NinjaScript.

You can find the system bar types under (My) Documents\NinjaTrader 7\bin\Custom\Types and the file will be named @BarTypes.

Thanks very much, Koganam and Patrick. I had indeed looked in 'BarTypes' but it is simply beyond my competence to try to play around with this, all the more so as this requires unsupported code.

If I could get the max/min of the tick chart for the period of the last bar, my approach would be to use the 'DrawLine' method to adjoin a line to each bar.

From what you said, Patrick, the best (only?) approach would be to add a tick chart (which of course needn't be visible).

I've looked in Help but I'm still not sure how to proceed.

So any ideas as to how to get the time of the open and close of the previous bar using 'time' methods would be really appreciated.

Thanks.

Thanks.

DateTime OpenOfPreviousBar = Time[2]; //equal to close of bar previous to previous bar
DateTime CloseOfPreviousBar = Time[1];

Thanks, Koganam.

I'll have a go at applying these time methods to a tick chart, which I think I may just be able to do myself. If I fail miserably (as usually happens), I'll be back...

Much obliged.

Thank's for the interest in this everyone. This is way beyond my skill level, all the help is greatly appreciated.
