It's no lie that money lies at the center of how our ever-increasingly complex and globalised society functions. Already in 1611 humans were trading stocks. Yet to this day not much has changed about who does it and how. Most of the money circulating in the stock market belongs to institutional investors instead of everyday people. We set out to try and change that by creating a simple securities exchange platform that is modern, easy to use and extensible.
What it does
The Rialto platform allows anyone regardless of prior knowledge to get started with trading securities. In less than 10 clicks from a users first visit to the site they are able to have fully traded their first security. Not only does Rialto offer best-in-class simplicity, but uses modern technologies under the hood to allow parallel and real time trades with no extra hassle.
How we built it
Challenges we ran into
Turns out the bidirectional data flow, which the Sockets provide is nice until it's not. Managing the overhead this caused ended up costing us time, but in the end we managed and came up with a solution that we're pretty happy with. However if we were to build this product again from scratch we would opt for a mixed approach where normal HTTP requests are used for applications such as authentication, and single-use data fetching and only using WebSockets for applications where real-time data truly matters such as live securities views.
Accomplishments that we're proud of
We're proud of the progress we made during the 36 hours especially considering our small team size and we're also happy with the flows to trade securities.
What we learned
We learned a lot about WebSockets, relational data, but perhaps the most insightful thing we learned is how far you can get with effective time management.
What's next for Rialto Finance
Hopefully to expand our product's use case to the real world and bring trading to the hands of more people.
