From a technology stand point this is intriguing. But that much said, I am anti-capitalist. The one downside to HF radio is that the available bandwidth is tiny. You’d have to create a compression algorith capable of compressing enough data to complete a trade. Also HF is very susceptible to changing atmospheric conditions. I am a licensed ham radio operator.
I am also a licensed ham, and you are right. HF digital modes are very low data rate. A low bits/sec data rate because of the limited bandwidth will result in high latency for any nontrivial message length. FT8 is only 6b/sec for comparison. I’m curious to learn more about how they would use the spectrum.
I’ve yet to play with FT8. I’ve had to sell my radio equipment when I became disabled. One day, I’ll get back into it again.
1800 symbols per second is the benchmark for shortwave data transmission.

Not sure exactly how useful that would be, but the latency is low: 0.01 seconds to cross the width of the USA.
A round trip packet from NY to SF takes 0.05 seconds, a fifth of the speed. Fibre is quick, but not as quick as radio.
There’s about 1400 bytes usable in a TCP packet, versus the 1800 symbols per second over shortwave. Lots of TCP packets can be exchanged per second.
I don’t see the value proposition.
Maybe they should just slow TF down and trade like us normal peons
Pfffttt, they aren’t thinking grand enough. Maybe if the use UHF they could then trade at a UHF frequency of trading.
