1. An automated system implemented on a server comprising:a processor and a non-transitory computer readable medium coupled to the processor, wherein the non-transitory computer readable medium stores program instructions executable by the processor for investing in financial securities useable by a plurality of users, comprising:
a trader grouping graphical user interface displaying data fields to the plurality of users allowing entry of user profile data, including at least one selected from the group of risk aversion, available trading capital and trading frequency;
a trader grouping engine displaying the trader grouping graphical user interface to the plurality of users, receiving the user profile data entered, storing the user profile data in a database and comparing the user profile data between different users to ascertain a measure of similarity between a plurality of users and grouping at least two users based upon the measure of similarity between the profile data of a first user and a second user and upon a user experience value attributed to the first user;
a trading graphical user interface displaying financial security identification and pricing information and data entry fields, including a blank for number of securities bought/sold that may be filled by the first user in making a buy/sell order;
a trading engine displaying the trading graphical user interface to the first user, allowing the first user to enter trading data for a trade of financial securities, recording the trading data in a trading database and executing the trade by communicating the trading data associated with the trade to a trading agent who executes the trade for the first user where the executed trade is further recorded in the trading database, the executed trade contributing to: a record of profit/loss attributed to the trading activity of the first user and a portfolio of the first user which are presented to the second user as criteria for deciding whether to mimic the trading activity of the first user;
a profit/loss calculation engine that calculates the record of profit/loss associated with at least one trade by the first user and stores the record of profit/loss in the trading database;
a trading activity reporting engine that identifies the second user that has been grouped with the first user by the grouping engine and displays to the second user on a display screen: a first portion of the first user's trading activity data including an identifier for the first user and the record of profit/loss associated with the trading activity of the first user and presenting a message to the second user inviting the second user to elect to receive further data concerning the first user's trades and upon electing to receive further data, a relationship is established between the first user and the second user in which the second user has access to the first user's trading data beyond the first portion of the trading activity data, the relationship establishing the second user as a mimicker with the ability to mimic the first user's trading activity, the trading activity reporting engine calculating the user experience value indicative of trading success of the first user wherein a first user's success E is calculated using the following factors related by the following equation: E(p,f,m)=?S(p)+Bf+Cm, where E is dependent on the first user's portfolio (p), the first user's current number of followers (f), and the first user's current number of mimickers (m), and where S is a function for calculating a portfolio's moving average success, and B and C are non-zero, weight constants; and
a trade mimicking engine, the trade mimicking engine presenting the first user's trading data to the second user via a trade mimicking graphical user interface, which displays the first user's trading data including investment changes made during the trade, including identifying the financial securities traded along with the numbers of financial securities traded, the trade mimicking engine through the trade mimicking graphical user interface providing the option to the second user to mimic the first user's trade in whole or part and based upon the second user's selections entered into the trade mimicking graphical user interface, the trade mimicking engine automatically executing the resultant trade for the second user.
