So I bought 2 books on the subject and have been playing with the technology for couple of days now. And I must say things have improved A LOT since I’ve been doing Web Development.
Back in 2003 I were working on an Order Management System and my boss being a perfectionist and a great fan of Google, requested that we created an order input form, comprised of 6 tabs without any postbacks to the server (‘coz they are evil)
The traders would no longer have to remember the exact ticker, as long as they knew the name the app would asynchronously go and fetch corresponding tickers.
Once you selected a ticker, you would be presented with some information about the instrument, settlement date and the fees would automatically default based on the market where the instrument was traded on, if it was a bond it will also calculate yield, time to maturity, for convertible bonds it will show you all the greeks and much more (limits, holiday calender per market, settlement periods, compliance stuff, history of changes etc). Not only that but the could switch to a different tab effortlessly to see the executions and modify them if necessary. I’m not going to go to cover the other 95% of features, but the app was brilliant in terms of usability, only Google could complete.
