Displaying text on graph

Hello,
I've been trying to display text with terrible results. Maybe somebody can give me a hint.

Let's say I want to display a buy signal when Stoch < 20
I have the IF, and when it's true I say:
ExtMapBuffer1[i]=Close[i]
Now, in the chart I'd like to know the price.
I'm looking for something like:
DisplayText(Close[i] , Low[i]-Point*5)
so that it displays the price (Close[i]) below the candle (Low[i]-Point*5)

If there's no single command, maybe a link or tutorial?

Thanks in advance.

I think you will need the CreateObject (... text, location, etc). Look at some of the indicators that do that already - they are numerous.

Displaying text is not exactly the problem.
The problem is how can I display it above or below the candle.

I've tried to look for some indicator here in FF, to see the mq4 file and see how the price is displayed above or below the candle.

However the indicators that I've found that display text, do it in a specific (x,y) (like a clock or a price display).

If anyone remembers an indicator with the mq4 code that displays price on candles, I'd really appreciate it.

Thanks in advance.
