TELEGRAM SIGNAL TRANSFORMED INTO ARROW ON MT4

Mi serve un programma che prende segnale telegram e lo invia a MT4 disegnando una freccia su o giù.                                                            I need a program that takes telegram signal and sends it to MT4 drawing an up or down arrow

OK
I was wrong.
 I need a utility that reads Telegram signal
 and writes the up or down arrow on the graph.
