The problem Kevin Slavin described here is very real. Humans are indeed getting clueless on how these bot driven markets are doing.
His suggestions, interestingly, is exactly what I am trying to accomplish with the development of the Real-Time Trading Assistant, a tool I have created to deliver meanings and context about the markets in a way human can understand.
I think I am on the right path in combining human intelligence and data driven inference information into something easier to use for human traders in real-time. As a minimum, it is much more practical than using tons of trading indicators. Too much information, or information overload, is often the main reason why traders are having a hard time in making the right trading decisions.
A clip from CNN on Citadel. Retail traders should be aware of what these guys do.
For years, I have told my members that the stock market nowadays is not the one before year 2000. Back then it was a game without that many mega size hedge funds and bots. Now, we are mainly playing in a eco system with bots driving the flow. There is nothing to be fearful of them though. Bots in aggregation are stupid, predictable and very easy to beat.
