Adding multiple data-series & perform multiple operation on these

[shaista parveen]

In this i want to take multiple dataSeries in my strategy like this

protected override void OnStateChange()
{
if (State == State.Configure)
{
AddDataSeries("ES 09-16", BarsPeriodType.Tick, 100);
AddDataSeries("6E 09-19", BarsPeriodType.Tick, 100);
AddDataSeries("6B 12-19", BarsPeriodType.Tick, 100);
AddDataSeries("ZB 09-16", BarsPeriodType.Tick, 100);
AddDataSeries("ZE 09-16", BarsPeriodType.Tick, 100);

}
}

now i want to store these data but how?

And also i want difference of
("ES 09-16") - ("6E 09-19")
("ES 09-16") - ( "6B 12-19" )
("ES 09-16") - ( "ZB 09-16")
("ES 09-16" ) - ( "ZE 09-16")

stores these differencese values on CLOSE price

But how can i get return values of that which are adding my strategy by AddDataSeries() method




please reply me anyone

Hello shaista parveen ,

Thanks for your post.

When you add multiple data series to a script you can reference them by using the plurals of Open, High, Low and Close, IE: Opens, Highs, Lows, Closes. To identify the particular data series, when added in state.Configure, the first added data series will be BarsArray indexed as [1], the 2nd added would be [2], the third added would be [3], etc, etc. The chart bars, that the script is applied to will be identified as [0]. The plurals use two indexes, the first is the bars array as previously advised, the 2nd index will be the specific bar to pull the data of. For example (using your sample code):

Closes[2][0] would be the close price of the currently processed bar of the 6E 09-19.
Highs[1][2] would be the high price of 2 bars ago of the ES 09-16
Lows[3][0] would be the low price of the current bar of the 6B 12-19

If you want to store the math differences into another array then you would need to create a private data series which will have the same number of array slots as the chart bars. Please see: https://ninjatrader.com/support/help...8/?seriest.htm If you created the data series with the name of ES6Ediff then an example of assigning the difference would look like:

if (BarsInProgress == 0) // run this when the chart bars call the OnBarUpdate method
{
ES6Ediff[0] = Closes[1][0] - Closes[2][0]; // store the diff of ES - 6E into the data series ES6Ediff
}

Hello shaista parveen,

Thanks for your replies.

As previously advised, "To be clear, we do not provide a code writing, debugging service as we are a small team. "

If your strategy does not compile, please see this tip: https://ninjatrader.com/support/help...jascript_p.htm

If your strategy compiles, then you can easily verify if your strategy is working correctly by applying it to your instrument and using the SIM101 account and enabling the strategy. If there are no errors shown in the "log" tab of the control center then that would mean the strategy has not generated any run time errors.

If when you run the strategy there are errors then it would be up to you to debug your strategy. Debugging is a process to determine what errors are occuring in your script. We have assembled some tips to assist you in the debugging effort: https://ninjatrader.com/support/help...script_cod.htm
