Stock Simulator from Investopedia
A colleague of mine pointed out this very helpful Stock Simulator from Investopedia. Basically it simulates the experience of trading in the stock market by connecting to a real-life data feed and allowing you to invest $100,000 of virtual cash in your choice of stocks.
This is how sample portfolio looks like:
I found it is very useful for everybody from beginners who have never placed a trade to sophisticated investors who are looking to test out advanced investing strategies.
Certainly, It can educate a person in more detail about market terminology like Limit/Stop orders,Day Order, Good Till Canceled. It also provides hands-on experience for beginners & students without getting their hands burned in stock market.
