Don’t spend too much time.. Based on my limited observations,
- As of 2007, the top dog was java.
- The dominance is even stronger in 2018.
- Q: how about in 10 years?
- A: I feel java will remain #1
Q: Why do I consider buy-side, sell-side and other financial tech shops as a whole and why don’t I include google finance?
A: … because there’s mobility between sub-domains within, and entry barrier from outside.
Buy-side tend to use more c++; Banks usually favor java; Exchanges tend to use … both c++ and java. The latency advantage of c++ isn’t that significant to a major exchange like Nsdq.
