I'm coming off a career designing analytical apps for FCMs, hedge funds, and other financial services firms. Boiling it down, most of my work has been pretty screens and reports to analyze and rank trader performance, analyze portfolio risk in real-time, fire alerts, etc. A lot of my work has also been in the area of hedge fund administration: Keeping track of pool investors, master/feeder interactions, allocation of P/L and fees, etc. So accounting tools, in other words. Not terribly exciting stuff but it paid well. So now I can either retire or pursue another project. With that in mind, I'm trying to get a sense from the trading community if there's some software/app market niche that hasn't yet been filled -- or perhaps one that HAS been filled, but the product(s) are just too expensive for retail trader use. I was thinking of building a platform that would hook into trader accounts at IBKR and other trading firms, provide in-depth performance analysis, allow users to share their data with other site users, maintain leader boards, create funds and apply fees, etc. But it looks like FundSeeder has that game pretty well covered; and they're offering it free of charge. Anything else you personally would like to see built?
