Hello,
I have been trying to show text with terrible results. Maybe somebody can give me a hint.

Let us say I want to exhibit a buy signal when Stoch lt; 20
I've the IF, and when it's true I say:
ExtMapBuffer1[I]=Close[I]
Today, at the chart I'd like to know the price.
I am looking for something like:
DisplayText(Close[I], Low[I]-Stage 5)
so that it shows exactly the price (Close[I]) below the candle (Low[I]-Stage *5)

If there is no single control, maybe a tutorial or link?

Thank you in advance.
