Hello qwert12,

Unfortunately this not supported.

However, you can plot multiple instruments in one chart 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.
