Code help - text in a signal

["marika11" <marika11@xxxxxxxxx>]

Hi,
I usually put 3 chart in a workspace with the same strategy but different
inputs; I'd like recognize what input in every chart without looking at
format analysis techniques.
Can You point me a way to show the strategy's inputs on the chart (on the
last bar I think), id est a formula (for the text) to add to my signal code?
thanks
Mario
