Get data from PC program to arduino

hello,

I'm wondering is it posible to get data from PC program to arduino?
I want to build something like telegraph. Get data from program "MetaTrader4" and show that data in LED matrix.
Maybe someone will tell me where to start?

I have no experience with metatrader.
Can you configure it to send the data required, to a serial port ?

This demo shows how to communicate with an Arduino using Python.

...R

I dont know how to send data required to serial port. This program can export some information to excel file but not everything what I need.
I think I have to use RX and TX to do this, but dont have any experience with RX and TX.
Or maby is arduino model which do simular things like I need?

If your PC is connected to the Arduino using a USB cable you don't have to worry about Rx and Tx.
Have you looked at my Python code?
If you can get the Metatrader program to write data to a text file you can easily read that file with Python.
You have not said whether the Metatrader program can send data directly over a COM port.
