Trading Platform built on Silverlight?

I've had an idea for some time now to write a trading platform application similar to think or swim in Silverlight.

First of all is it something that one person can do in a reasonable time-frame?

Ok next question is how would t开发者_开发技巧he performance of the Silverlight be running such a memory intensive application? Will it scale?

Nearly all trading platforms run locally on the machine, there must be a reason for that instead of building it on top of Adobe Air or Silverlight?

Last but not least, would users be frustrated by forcing them to install Silverlight plugin or is it something that people have no problem installing on their machines?

Most likely not... ThinkOrSwim has been in the business for a LONG time, so duplicating all of their effort is pretty much impossible to do with one person. If you start small you might be able to do some things, but it's quite challenging. Furthermore, if you try to build ThinOrSwim in Silverlight it's almost like building Windows in JavaScript: it simply doesn't make sense.

TOS is not just a web site, it's a brokerage... that means that they have to maintain connectivity to exchanges which is VERY bandwidth intensive and hardware intensive. You would have to connect to exchanges too or, at the very least, connect to another brokerage. In other words, your Silverlight will only be a front-end and nothing else. At some point you will have a central server where your users connect to unless you're just building a front end to another brokerage API like the Interactive Brokers API

Trading platforms tend to be very CPU intensive too, so the closer to the hardware the better... Adobe Air and Silverlight add a level of indirection which impacts performance.

I don't think that would be a concern... installing Silverlight is pretty easy to do, so I doubt they will see it as a big pain. The only issue, as far as I can see, is with the performance.

I have been part of a team that developed one of the worlds first Silverlight trading systems back in 2008 when Silverlight 2 was still in Beta. We released it to production 4 days after Silverlight 2 RTW became available.

The performance of the application wasn't a problem but the bandwidth consumed by sending data from the stock market down to the client was a problem as some of our users connected using a GPRS connection. With Silverlight 4 out and Silverlight 5 on the way it would definitely be possible to code a trading station within a reasonable time frame.
