The interesting part is that they started from nothing - no "previous art" - and worked out a complex, sophisticated system, the entirety of a stock market and all its associated mechanisms, in a few decades. Economic pressure is an amazing driver of creation and innovation, it seems.
This might not be true, I'm starting to think history might be twisted, even (dare I say?) lies. Maybe these people got the idea from older societies. Who knows.
One thing is certain, though. Our generation is going through a massive conflux of a cycle right now.
While yes options have been trading since the 1600's and probably even before, right around 1970 everything started to accelerate. For unknown reasons, the last 100 years has seen unprecedented growth, and we all take it for granted.
But right around the 70's computers started popping up, being commoditized. People started to use these computers for everyday use. It was our old buddy Fischer Black who thought about the idea if trading could be automated (Market making, not automated trading systems).
Around the same time our other buddy Claude Shannon was creating wearable computers and using it to bet at casinos then subsequently the markets with the infamous Ed Thorp.
1970's the NYSE introduced the "designated order turnaround" (DOT) which electronically routed orders to the floor. This was revolutionary. Then the war of the fiber optic cables. Who could get information 0.00000000001 seconds faster wins. Then program (algo) trading, the automation of index arb, the abolition of human market makers and the rise of the machines.
All of this in a span of a few decades. This growth is taken granted for, and we are living through it right now.
