Printing pip number on chart

Hi,

I'm teaching myself MQL4 and got the attached indicator to play with (iGap). It draws up and down arrows when a gap occurs above a certain pip amount (SizeGAP). What I would like to add to it is for it to print on the chart by the up or down arrows the size of the gap (number of pips). I can declare something like:

double Range = MathAbs(PrevClose - CurrOpen);

but I can't see how I can print this value by the arrows on the chart. Can anyone please help?

Thanks

There are 2 objects - OBJ_TEXT and OBJ_LABEL that allow you to annotate the chart. I think OBJ_LABEL is more suited to your purposes because you want to annotate the gap, whereas OBJ_TEXT would place the annotation at some designated spot on the chart in terms of X and Y pixels.

Thanks codemeister for your help. Much appreciated.
