Scope of Indicators

Yesterday I adjusted one of my charts to have various indicators display for specific symbols by changing the scope of the indicators to those particular instruments. I ran into a few issues when transferring to a second computer:

1) I saved the definition. Upon opening in the 2nd computer, those indicators were gone.

2) I redrew the indicators in the chart on the 2nd computer, and set the scope of each indicator for each symbol it pertained to. Upon starting the "slideshow" mode on the chart, it would not cycle off the first instrument, but rather kept recalculating and intervention caused the platform to crash each time. Once I removed the indicators, the slideshow worked again.

Is there any way to save a definition with certain indicators set to only display for certain instruments? Can you run a slideshow with indicators that are set to have a scope of "This chart, this instrument"?

Scope of Indicators

All indicators with standard scope (This Chart Any Instrument) are considered specific to that saved chart object and are responsive to a change of symbol in the chart. All other scopes are what you can think of as "optonal indicators", for example, a reference line created with scope "This Chart, This Instrument" are indicators that are conditionally loaded into the chart only when a specific instrument you specify is the main symbol in the chart. Change the chart to another ticker symbol, the reference line is not present any longer; change it back to the specified symbol and the reference line appears. Other scopes, such as "All Charts, This Instrument" will cause some indicator to be conditionally added to any charts you open on some symbol.

When you export a chart that is open in Investor/RT by right-clicking in the chart and choose Save > Definition... or perhaps Copy to Clipboard > Chart Definition, or using the Object Manager, the definition that results wil contain those indicators present in the chart at that time. Any conditional scope indicators will not be exported unless they are present in the open chart. Furthermore, any conditional scope indicators that are present will be exported with standard scope This Chart Any Instrument. These rationale for this is that we do not want the recipient of such a chart to suddenly begin seeing "All Charts" and other scoped indicators affecting the entire Investor/RT system. Instead, the receipient will see only the indicators imported; there will be no effects on other charts.  Of course, the recipient may later edit any indicator to change its scope.

Before you export a chart definition you can double click inside the chart to view the Chart Element Manager window. Click the "Chart" radio button to see the list of every indicator presently inside the chart. This list is what will get exported when you save the chart definition.

Does the scope of "This chart

Does the scope of "This chart, this instrument" on indicators not work with slide shows? My platform crashes every time I attempt to start a slideshow with indicators utilizing this scope setting. When I change it to "This chart, all instruments", the slideshow functions fine.

Scope and Slideshow

Worked fine in my testing.  Maybe share your chart definition and which indicator specifically you are setting to This Instrument scope and we'll test and try to reproduce here.  Also what symbol is it switching to when the issue occurs?

Here is the chart:

Here is the chart:

https://www.linnsoft.com/charts/30-min-w-daily-esh9

The initial symbol is ESH9, the following symbol is NQH9. It is meant to cycle through a watch list of several symbols. The VWAP and Profile indicators are set for "This chart, this instrument ESH9". When I start the slideshow, the platform hangs. If I remove the scope setting, the slideshow works fine.
