Is there a method or an example of using an indicator, (such as DPO) on an external symbol (Such as SPX) ? Or...what would the code look like?

Thanks,

An indicator accepting a DataSeries or a Bars object (that is, any indicator) can be applied to an external symbol. The idea is to pass the "handle" of the DataSeries/Bars object (DataSeries in case of DPO) to the indicator. There are numerous examples if you search the forum:

Technical Indicators on External Symbol's Pane
External Symbol with Indicator

For example, you defined DPO of the current Bars symbol (let's say Google) being charted as:

And the DPO of Microsoft would be:
