█  CONCEPTS


There are occasions when one needs to provide script users with multiple input source selections while still allowing the selection of an external input. This is usually impossible because for external indicators to appear in an input widget's dropdown menu, only one input.source() call must be used in the script. If multiple calls are used, then no external indicator can be selected in any of the script's input widgets.

This script demonstrates how you can provide input sources offering a selection among the usual source built-ins (open, high, low, close, hl2, hlc3, ohlc4, hlcc4), but without the ability for users to select an external indicator. This allows your script to use multiple source inputs while still using one source input allowing the selection of an external input.
