We’re ready to announce that our Indicator on indicator feature now supports multiple external inputs, up from the previous limit of one. These multiple external inputs can even originate from different indicators.
Here’s a sample strategy script with two input.source() calls:
//@version=5
strategy("Value Area Strategy", overlay = true)
sourceLongInput = input.source(low, "Enter Long after crossing")
sourceShortInput = input.source(high, "Enter Short after crossing")
buyEntry = ta.crossover(close, sourceLongInput)
sellEntry = ta.crossunder(close, sourceShortInput)
if buyEntry
strategy.entry("LongEntry", strategy.long)
if sellEntry
strategy.entry("SellEntry", strategy.short)
plot(sourceLongInput, "Long entry source")
plot(sourceShortInput, "Short entry source", color.red)
You could, for example, link this strategy with sources from the “Session Volume Profile” built-in indicator by selecting “Value Area High (VAH)” and “Value Area Low (VAL)” as external inputs from the strategy’s inputs. To do so, first make sure both scripts are loaded on your chart, then bring up the strategy’s “Settings/Inputs” tab and select the relevant source from each of its two source input fields’ dropdown menu.
Multiple external inputs will work with Deep Backtesting, so Premium plan holders can test strategies with multiple inputs on all data available in TradingView data storage.
Note that the sources used as external inputs must originate from indicators; they cannot originate from strategies. Also, external input sources can originate from at most ten different indicators.
You will find more information on this feature in the Help Center and in the Pine Script™ User Manual and Reference Manual.
