Custom made indicator not working

[Federico Sistri]

Hello all.

I have written a simple indicator that should plot labels on chart.

When I compile it, it returns no errors.

But when I load it on the chart, it does not display the labels and it is removed without errors.

I cannot understand what I am doing wrong, could someone please help me find the error(s)?

TIA.
