Must these raids happen in conditions of low liquidity, or can they hapen during pit hours too?
Are the bots knowledgeable traders? I mean, crude oil is a commodity that has real value, and if the bots push the price too far for too long they could get stuck with making or taking delivery.
Great questions.
It's impossible to attack when there is a thick stack of limit orders from other parties. The attacks always occur during "lulls" of some kind. Note the market is now much thinner than in the past- many human traders have left the business, especially at banks. So we have lulls during the proper trading day as well.
As for value, it was the banks and the big commodity hedge funds (like Clive, Centaurus) that used to step in and establish a floor of value. With them gone, the "bid" has all-but disappeared.
