A $10 Oanda account will have the same trade execution and spread as a $10,000 Oanda account. This is fine to use as a demo or practice account. There are a few other brokers that have cent accounts IBFX and LiteForex do. I am sure there are more. A cent account at other brokers may have different leverage and spreads then a micro or mini account. Check this out before you open an account, this may not matter to you but you should know what the differences are. I like Oanda the charting is primitive on the java platform but the order placement and management is A+. You can always chart on an MT4 demo.
MT4 is short for metatrader 4 its the most common trading platform around for us retail traders. There are a ton of custom indicators, scripts and EAs (robot traders) for free just use Google. Most brokers offer MT4. Its great for charting. Just open a demo account at a broker that offers MT4. Oanda does offer MT4 however the smallest trade on Oanda mt4 you can place is 1000 units.
I think I remember reading that someone said that he would use MT4 to do his chart analysis but then use Oanda’s platform to enter his 1 pair trade. Someone else said that it would get really confusing. Do you have an opinion?
