We have two types of trading, what should we do, Go for live one or practice one?
Live trading or "going live" is what most aspiring forex traders want to move on to after being successful trading a demo account. This means that you place real funds at risk on each trade, and your portfolio has to take whatever the market offers you in terms of profit or loss. Most traders just starting out in forex will want to see that their trading strategy works well on a demo account before taking the plunge to start live trading.
Having an opportunity to practice trading using a real forex trading platform and real-time pricing is what demo accounts are all about, especially for newer forex traders. Basically, it really pays to make any mistakes first using a demo account so that you can learn from them relatively painlessly, rather than when you have begun to live trade using a funded portfolio.
