# 1.6	Indicator-on-indicator

Your UDI automatically participates in the chart's ability to apply one indicator to another indicator (unless you turn this off using the noIOI setting).

 Another indicator – for example, a moving average – can be applied to any of the plots of your indicator. And, if your indicator has a Source field, then it can receive the values of another indicator rather than candle data such as close prices.
