> He was pretty early, and quite contrarian, in betting on computer and quant strategies and thus took the “low hanging fruit” early on (def wasn’t low hanging back then when no one knew or believed in computer trades strategies)

Also the data back then was much harder to acquire. Bloomberg didn't even exist at the time.

You could subscribe to a service and get pricing data and news. My father did it (with reverse effect) and I remember him using his fancy 9600baud modem to get his portfolio prices for the day (last 24h summaries, 5m and 1m candles).

There was no Bloomberg but there was compuserve and AOL and usenet and various other forms of financial forums.

Yep, my dad was getting live stock quotes back in the 80's.
