Basic Test Trading System

Sedang Disiapkan

I'm not after any complicated trading theories, just a GUI that will allow users to buy/sell a stock at a the current market price of any FTSE100 company. This buy/sell should then be tracked and priced for profit/loss.

Terminology: the negative or positive amounts of each stock is the 'position' of the user/trader for that stock. Multiple positions form a 'portfolio'.

The important pricing figures are actual profit/loss, comprised of the 'actual' buy/sell of a position, and the theoretical profit/loss; if they sold/bought stock to close all current positions.

For example, a buy at $100 of stock ABC, followed by another buy of the same stock at $110, is an actual loss of $210 (as we have needed that amount to buy the stock). If the stock is currently trading at $120, that's a theoretical profit/loss of $30, and should be displayed against that stock, as well as both figures contributing towards total profit/loss. A 'current day' figure would be useful too, to allow users to see how they are doing on individual days.

I would like the option for a single user to have multiple portfolios. The positions being owned by a portfolio (and the profit/loss of each portfolio to be distinct). Consider these as different profiles/users almost, does that make sense?

For example portfolio one could have a 3x buy position of Barclays, and a 1x sell position of Experian. But this would be independent of portfolio 2. 3 Portfolios would be sufficient.

All the positions should be priced using something like googlefinance. Example price feed here:

docs.google.com/spreadsheets/d/19jYetE4-k5bOaYBsdaw-l_TLO0eVEFWB7ZRIaqhXoAg/edit#gid=0

I believe the current API limit is 100 requests per 100 seconds ([url removed, login to view]) so more than enough.

The full googefinance functions can be found here

The main actual trading page of the system should be similar to the google doc above, with daily high and low columns. There should be a buy and sell button next to this imformation, to allow users to easily buy/sell the selected stock. A green or red color change on the 'change' box of each stock would be useful, to reflect a positive or negative change. The final column would be a button that opens up the historic price information on google (avoiding the need for the system to keep historic data, when google does a perfectly good job including graphing!):
