Subtracting a value from the intraday quote

[methusalum]

How would one create an array of daily values, and then use them in an intraday chart or indicator?
For instance, subtracting the london fix price for gold from the intraday price.
Any ideas? or pointers would be appreciated. As I am not familar with the object model within ninjatrader, how do I compare an array of datavalues and datetimevalues from the chart with one that I create?
Thanks

Hi methusalum, multi-instrument charting (daily values shown on an intraday chart) isn't supported for NinjaTrader 6.5. This has been addressed in NinjaTrader 7:

New Multi-Series Charting
You can now mix multiple series on a single chart without limitations seen in other platforms. We have introduced a new chart level property "Equidistant bar spacing" which is automatically set to false when mixing more than one series. What this does is creates a time axis that is void of any missing bars so that mixed series of any type can all be accurately aligned to time. When this property is set to true, bars have even space between them and missing time bars are excluded.

If the "London fix price" is available with your data feed, there is a work around or two available. If the data isn't available, this would still be possible, but challenging to implement. NinjaScript is derived from C# so anything you can do with C# is technically possible to translate over to NinjaScript.

If you'd like a professionally coded solution, you can contact one of our certified NinjaScript consultants.
