I suspect this is related to high-speed trading in the stock, bond and futures markets. A number of large financial institutions have noted that there are brief differences in the prices of various financial instruments between the various markets -- for example, NY and Chicago. If they can act fast enough, they can buy in the cheaper market and sell at a profit in the more expensive market before the differences iron themselves out. These institutions have invested a lot in high-speed internet connections between their offices physically near the various markets so they can exploit these differences. Looks like someone is going to try to speed things up by using a SW radio link. Note that the FCC applications were filed with a request for confidential treatment of certain details.

Thus sounds interesting. Googling however has failed me. Can anybody share
the original article or a link to more info?

According to Experimental News #8, the FCC has granted a license and construction permit to Amberwell LLC to transmit data in 15 frequency segments between 7490 and 14520 khz with the experimental license WN2XKQ. Among the special conditions WN2XKQ is not to cause interference to any existing service. Power will be 24kw and this experimental license will expire on March 1, 2025. Bill Smith, Douglas, MA
