Create chart from multiple charts

[qwertyjjj]

I would like to create a chart or indicator that is actually a combination of 2 stocks.
eg if stock 1 is at $200
And stock 2 is at $50
The chart/indicator should actually plot a value of 250.
Ideally it should have candles as well.
Is this possible?

Hello quertyjjj,

Thank you for your reply.

There would not be a built-in way to do this in the platform. To clarify, when you say "Ideally it should have candles as well", do you mean you want candles for both series plotted on the chart and then a indicator plot showing a line with the total value, or were you wanting candles made from the indicator value? What would be the OHLC of the bars if so, since you've only specified a single value that's just the total of the two values?

Thanks in advance; I look forward to assisting you further.

Hi
yes candles of ohlc.
Just one candle for each time setting.
If if I open a 15 min chart
Stock 1 o 200 h 210 l 190 c 200
Stock 2 o 50 h 55 l 45 c 50

The chart should show an ohlc candle with
O 250 h 265 l 235 c 250

Ideally I want a chart that shows this. The only reason for the indicator is that I assumed a custom chart was not possible so I would have to build the chart in an indicator instead

Hello qwertyjjj,

Thank you for your reply.

You could definitely do this in an indicator. This indicator from our User App Share provides a basic outline of creating an indicator that plots candlesticks:

https://ninjatraderecosystem.com/user-app-share-download/candlestick-indicators-sample/

This could be easily modified to add a second data series using AddDataSeries() (https://ninjatrader.com/support/help...dataseries.htm) and then add the opens/highs/lows/closes together and then would plot those added values. In the example it's just a single data series, and just uses the OHLC for that series to plot in an indicator panel, but all you'd really have to do to modify it is add the secondary series and then do something like:

IndOpen[0] = Opens[0][0] + Opens[1][0];
IndHigh[0] = Highs[0][0] + Highs[1][0];
IndLow[0] = Lows[0][0] + Lows[1][0];
IndClose[0] = Closes[0][0] + Closes[1][0];

The rest of the existing code in the example would take care of the plotting part for you.

Keep in mind that this would only properly function on time based bars, as with tick based/custom bar types the bars wouldn't be at the same times and you'd get some odd values.
