Currently got few weeks of works done, mostly focused on the Back testing part.
I focus a lot on performance, it's all native es6 (Classical inheritance / Promise / Events based). For example, I made some scripts that turn tick data to binary Float64 files, and the core platform gets benchmarks on every change.
I have done a far bit of Metatrader and tries a full JS platform before some years ago.. But learned a lot and just starting again :)
Ideally the platform is multi functional.. You can use it primarily for automatic trading, but manual trading is also possible. You can host it your self, run it local, or build a SaaS around it.
Let me know if you are a die-hard JS developer, both backend as Frontend is welcome :) experience with 2D canvas (not highcharts, too slow) and /or D3 etc, that's more than welcome.
Thanks
