It seemed crazy to me that none of the personal newsletter services out there let you just write the filter prompt yourself, so I built this. I think its much simpler and more flexible. Feedback welcome!

Is amazon web services not a service people pay for? People are currently buying computation (a service) with crypto. I spend ETH to deploy and execute code, in the exact same way I pay USD to AWS to deploy and execute my code.

That service is the point of the whole thing. The fees go to stakers who *execute your computation for you and ensure the integrity of the results*. ETH is analogous to credits on AWS. It's simply an execution environment with different properties from AWS.

Miners are incentivised with transaction fees alone after all the bitcoins are mined.

I suspect it will remain a toy, but agreed on those optimizations

Yeah I was planning on playing around with the performance/optimizing it. Didn't know about that binance data feed though, thanks.

Thanks! What would you suggest instead of a global/lazy static in this situation though? I recall struggling to pass some dynamically allocated structure into the hyper service instantiation.

Thanks for the info! I definitely did not know all of that :). I do work at a crypto exchange, but on the custody/stablecoin side, not the exchange team.

Can you elaborate a little on the "pinging" process to extract information? Sounds interesting

Leaking the number of orders seemed like a bad idea

I was imagining inserts at an unoccupied price level would be relatively rare in normal order book operation, so a Vec just seemed simpler

Feedback welcome! I'm sure I'm missing loads of Rust patterns and idioms...
