Hello murena80,

Thank you for writing in.

I would highly suggest taking a look at the Code Breaking Changes section of the NinjaTrader 8 help guide for a high level overview of the syntax changes you can expect between NinjaTrader 7 and 8: https://ninjatrader.com/support/help...ng_changes.htm

If you would like, I would be happy to forward you to our business development team who can connect you to a NinjaScript consultant to assist with converting your code.

Please, let us know if we may be of further assistance.

Hello Jessica,

thank you for link you have provided. I am trying to resolve some erro I am receiving in this indicator and found out that there is missing some part of the code which in NT7 was part of the userdefined method.


Here is more of the code

private double MyCCI(ISeries<double> input)
{
if (this.cacheMyCCI != null)
{
for (int i = 0; i < this.cacheMyCCI.Length; i++)
{
if (this.cacheMyCCI[i].EqualsInput(input))
{
return this.cacheMyCCI[i][0];
}
}
}
lock (checkMyCCI)
{
if (this.cacheMyCCI != null)
{
for (int k = 0; k < this.cacheMyCCI.Length; k++)
{
if (this.cacheMyCCI[k].EqualsInput(input))
{
return this.cacheMyCCI[k][0];
}
}
}
NinjaTrader.NinjaScript.Indicators.MyLineNew2 line = new NinjaTrader.NinjaScript.Indicators.MyLineNew2();

line.Input=(input);
// base.Indicators.AddPlot(line);
line.AddPlot(new Stroke(Brushes.Yellow,2),PlotStyle.Line, "");
NinjaTrader.NinjaScript.Indicators.MyLineNew2[] array = new NinjaTrader.NinjaScript.Indicators.MyLineNew2[(this.cacheMyCCI == null) ? 1 : (this.cacheMyCCI.Length + 1)];
if (this.cacheMyCCI != null)
{
this.cacheMyCCI.CopyTo(array, 0);
}
array[array.Length - 1] = line;
this.cacheMyCCI = array;
return line [0];

Thank you for this additional information miroslav. What questions may we answer about your code, or about the operation of NinjaTrader?

[miroslav]

well I was trying to search forum, help and other resources to get some hint to resolve this three lines. The rest looks ok.

[NinjaTrader_JessicaP]

It is not immediately obvious what your goal is with those three lines. Can you describe their function? line.Input is not a documented method.

[miroslav]

Hello,

yes, you are right line.Input is not standard method. What I want to achive it that line Input is same as input from plot
line:

private double MyCCI(ISeries<double> input)

with
Indicators.Add(line); = I would like to call plot and in the code you can see that I am trying to do it
line.SetUp(); = I would like to achive that plot "line" is set up.

Curious is that in NT7 it is working but in NT8 is not and I did not even find it in the code breaking changes

[NinjaTrader_JessicaP]

It looks like we need to examine your MyLineNew2 indicator's source. You should see a line in MyLineNew2 that looks like either

public Series<double> Input;

or

public ISeries<double> Input;

If you do not see either of these, please add them to your MyLineNew2 indicator's source and recompile. If you are still unable to set this variable, please let us know and we can investigate further.

Hello Jessica,

it helps to resolve the issue with input. With those two errors is my solution appropriate covnersion from NT7 ton NT8? I meant (line.AddPlot.......) and line.SetUp();?

One more thing it seems I am trying to reach index bar which is out or inder range. I am trying to catch error with Log(). Is there some example or approach to see how many bars need to be inserted in the condition (if(CurrentBar>=xyz) then do something.

thank you
