Pretty cool detective story about using an SDR HF radio to improve stock market trading times.

Not for me. I can't accept any SDR latency and do all my trading via single-conversion radios without the extra delays from multiple IF's and heterodyne mixing.

Ok, the 2nd article discussed an experimental license and power levels of 20KW to 50KW ( because if HF is unreliable at amateur power levels it is very reliable at 20KW to 50 kilowatt levels). And I assume they are using ALE to find the best frequency.

The interest by traders to "shave-time" to gain advantage is very old.

While the article I am linking to applies value statements claiming what was happening was "a crime" the 1830's courts of France exonerated the defendants, basically because they found a way to shave trading time in a way too novel for legal protection.

Enjoy.
