Background: I've been trading stocks/options for over 18+ years or so. I have accounts with your regular retail brokers - Etrade etc.
My question is, when people say they've done back testing - how are they doing this? Is someone willing to make a video on how to perform back testing? How is this done? What data is needed to perform back testing? Do you need a special service - is it free? What is the cost etc?
This is a totally new area for me, but I would like to learn more to help increase my profits and learn from others and mentor others.
Thanks.
