Hello!
Some interesting articles about using SW to do data transmissions.
Internet has a too high latency for these traders, so they wanna use shortwave with 20 kW.

The question is what the outcome is and which bands can be used by
them. I hope that they will not be allowed to use the ham radio or
broadcast bands because that will be the end for many broadcast station
that cannot afford a high power transmitter.
Worldwide ham radio and broadcasting is in danger if that will be the
future of these bands.
The petition is from the Shortwave Modernization Coalition (SMC), and
the whole docket can be found on the FCC web site ECFS as RM-11953.
They are asking for permission to use various existing Fixed Service
bands between 2 and 25 MHz. Right now, Fixed Services are allowed on the
HF bands for backup purposes, using SSB for voice, which uses 2.7 kHz
channels. There are also some data licensees. SMC is asking for
permission to use up to 50 kHz wide channels, up to 20 kW, and with a
relaxed out-of-channel emission standard that would put very loud junk
onto the amateur bands as well as interfere with other Fixed users,
like, say, competing traders. The Comment and Reply Comment periods have officially closed, though. It has received a lot of opposition. For one
thing, SMC wanted to be allowed very loose out-of-band emissions because
a more properly filtered transmitter would have a tiny bit more latency,
and flash traders take money from the rest of the market by being just a
smidge faster to execute. There is no public benefit to this, just
private gain for public harm.
