At first this follow-up comment really upset me. However, isn't it just a reflection of where we are now? So much is being discussed about AWS (and the likes) profiting from open source solutions without giving anything back. Isn't this comment just the pure reflection of a market place short-term trying to optimize profit without any regards to long-term benefits?
The lead of the OP is something to follow, though!
* Data capture (binary format, streaming, consistent)
* Exploratory research (InfluxDB into Jupyter)
* Back-testing (incl. order matching, very fast!)
* Live trading (suitable for HFT)
This framework has been designed for professional traders who emphasize full control, ultra low latency and a consistent back-testing framework.
Everything has been designed so you can own, control and deploy your own software stack.
Our primary focus is predictable ultra low latency during live trading.
We support Coinbase Pro and Deribit and we will soon add more exchanges.
The framework is not limited to cryptos: all interfaces are generic and have previously been tested against non-crypto exchanges.
We will always use the better (faster, more reliable, etc.) protocol offered by each exchange: that means FIX being strongly preferred to WebSocket. (REST is a non-starter for any kind of HFT).
Gateways are free to use during our "beta" testing: we will implement a license model early 2020 (allowing also private individuals to participate). Everything else will remain free!
Many more details in the linked document. In particular, the minimalistic "tutorial" towards the end, for those of you who want to try it out.
The reason I'm asking is that I've noticed companies often use their contributions for own marketing. And this is obviously great.
However, how can one validate if a company says "we're contributing $X/month", that it's really contributing and that it's ongoing?
