same is true of the American #stockmarket My financial advisors tell me it is often now 70% of the trading: high frequency algorithms based trades. 30% when I first started to ask in 2009. There are billions of decisions,but 70% or more made by machines. Happy for hedge funds and high frequency traders to have their own separate unequal exchange, leaving us out of their own weirdness: crypto contagion, credit default swap contagion, triple witching hours, etc.
