So a few things;
-PRT free version is end of day data
-IG markets use the PRT software and you can set up a Demo Account for free which gives you access to live data (I still remember the excitement when I first saw pip by pip charts ... quite intoxicating LOL
-either way when you get into the charts have a play is my suggestion
-The scan I screen shotted was found from; the main bar:
Display/ Proscreener / RSI hourly oversold
-If you want to set your own parameters hit the little spanner ..... there is a world of options for you to play with
-there is a users manual somewhere on the website or just google it.
