Graal Stock Market

[Gunderak]

Today I present you with a fully functional mini stock market.
Each player starts with $1,000 virtual cash (clientr.stockcash).
You can then purchase stocks (defined in the DBNPC "Stocks").
When the NYSE stock market is open, the stocks will update every second.
Whilst the NYSE market is closed players can still purchase stocks and sell, but won't make any profit or loss.
The configuration is pretty simple.
In the DBNPC "Stocks", just add the stock name and symbol to the array.
Then upload the weapon script and add it to whoever.
All code can be found in the attached file, Stocks.zip.
It's important the DBNPC is named "Stocks".
The code may not be the best way to do it all but it works and is fairly secure.
To purchase a stock, select it on the left and then change the quantity with the up/down buttons and click buy.
Selling, select it on the right hand side and click sell.

Edit:
v1.2
Updated code to provide live stock data when market is closed.
