I want to learn about forex trading,where do I start?

I want to learn about forex trading,where do I start-I downloaded some demo programs to start learning how to trade forex,but I look at it and get a migraine. I know nothing about forex trading or anything like it,but i am interested in getting into it,however I want to learn through a program and get some practice before getting into live trading.

Are there any demo programs or free online courses to explain to me how it works and how the programs work?

You may approach Institute of Bankers, London, they may conduct courses on Forex Trading.
Forex Trading involves buying and selling of different country currencies, Forward dealings, handling Imports and Exports etc. The currency dealing requires good perception of mind with ability to decide quickly. After theoretical knowledge a good training is essential.
