Which videos should I watch? Is there a 'line' function?

[joemiller]

I’m not interested at present in trading from the charts [I get the impression one can do that?]. I would like to learn how to generate stuff for display on Strategy Analyzer charts such as dots and Lines and whatever else could be available and useful.
Should I start by watching ‘chart’ videos and using the chart section of the Forum?

Regarding dots and lines, I have successfully used the ‘drawdot’ function [ie]
//DrawDot("My dot" + CurrentBar, true, 0, High[0] + 2*TickSize, Color.Red);

I unsuccessfully searched for a function which would draw a curve thru those dots…..is there such a function?

Not likely, unless you want to program your own Bezier curves. About the best you can do easily would be to join the dots with straight line segments.

Hello joemiller,

Thank you for your post.

You can trade from the Chart using Chart Trader: http://www.ninjatrader.com/support/h...art_trader.htm

So you wish to add drawing objects to your chart manually or via NinjaScript on the charts in the Strategy Analyzer?

There is no method to draw a curve via NinjaScript. However, using unsupported code you may be able to achieve this using the DrawCurve method in C#: http://msdn.microsoft.com/en-us/libr...(v=vs.90).aspx

You can also view a sample of custom plotting by going to Tools > Edit NinjaScript > indicator > CustomPlotSample.

Please let me know if I may be of further assistance.

thanks, that helps a lot ....it will keep me from going down some blind alleys.
I noticed that a moving average indicator was displayed on a strategy analyzer chart so can I write an indicator which [for conversation example only] would for instance plot a one day moving average of the closes and therefor pass thru the close of every bar?

do you agree that it sounds like I should watch an 'indicator' video?

should I spend time watching a 'chart' video?

I will go to the CustomPlotSample soon as I can, that one sounds like a good one

your kind of help is invaluable and is much appreciated.

Hello joemiller,

Thank you for your response.

I am not sure what you mean by passing a one day moving average. Are you looking for a moving average calculated from Daily bars but plotted on another series? Or are you running the backtest on the Daily bars and will add a 1 period moving average to the charts in the Strategy Analyzer charts?

I cannot say for certain where you need to begin on this. If you having trouble with charting I definitely recommend our charting webinar series.

lots of good stuff in that reply.

regarding a one day ma, I was wondering if for example a ten day ma of the closes slowly responds to daily changes and is displayed as a continuous line, then a one day ma would be a continuous line thru the closes....thus accomplishing the objective of displaying a line thru the closes. assuming the software accepts a request for a one day ma.

anyhow I have lots of suggestions from you to explore.

Drawline executes only once?

Hi again Patrick

The following drawline command appears to execute only once [ie] only one line segment is displayed on the chart...between the last day and the previous day to that.
What must I do to create all line segments [between all bars]

DrawLine("my line", false, 1, Close[1], 0, Close[0], Color.Black, DashStyle.Solid, 4);

[NinjaTrader_PatrickH]

Hello joemiller.

Thank you for your response.

Using DrawHorizontalLine() , you could set up a horizontal line that shows at the current price.
For information on DrawHorizontalLine() please visit the following link: http://www.ninjatrader.com/support/h...zontalline.htm

For the DrawLine(), you will need to add a variable to the tag otherwise since there is one tag there is only one line drawn. You can actually use CurrentBar to do this, and it will add the CurrentBar number to the tag.

DrawLine("my line"[B][U] + CurrentBar,[/U][/B] false, 1, Close[1], 0, Close[0], Color.Black, DashStyle.Solid, 4);

Please let me know if I may be of further assistance.
