Hi, thanks for the post. So you are looking to trade crude oil futures as an investment.
Ok, firstly, I cannot offer advice on crude oil trading, but I can give you a tip instead: Try the 500plus Oil trading platform, you can explore their software and system for free, you can trade as a test account with no outlay. Just download the package and give it a go.
If you try it out and decide to make a real trade, then you can get in on oil futures trading using their system for as little as a 50 USD outlay.
I hope that helps! let me know. Here's the link to their home page: http://www.plus500.com/Home.aspx?id=73&pl=2
