By the first weekend, regulators had discounted the possibility of trader error and focused on automated trades conducted on exchanges other than the NYSE.
However, CME Groupa large futures exchangestated that, insofar as stock index futures traded on CME Group were concerned, its investigation found no evidence for this or that high-frequency trading played a role, and in fact concluded that automated trading had contributed to market stability during the period of the crash.
Regulators found that high frequency traders exacerbated price declines. Regulators determined that high frequency traders sold aggressively to eliminate their positions and withdrew from the markets in the face of uncertainty.
One hypothesis, based on the analysis of bid-ask data by NanexLLC, is that HFTs send non-executable orders orders that are outside the bid-ask spread to exchanges in batches.

Berman,   the U. As prices in the futures market fell, there was a spillover into the equities markets.

However, based on the statements above, this cannot be true.
According to this paper, "order flow toxicity" can be measured as the probability that informed traders e. For that purpose, they developed the Volume-Synchronized Probability of Informed Trading VPIN Flow Toxicity metric, which delivered a real-time estimate of the conditions under which liquidity is being provided.
If the order imbalance becomes too toxic, market makers are forced out of the market. As they withdraw, liquidity disappears, which increases even more the concentration of toxic flow in the overall volume, which triggers a feedback mechanism that forces even more market makers out.
This cascading effect has caused hundreds of liquidity-induced crashes in the past, the flash crash being one major example of it. One hour before the flash crash, order flow toxicity was the highest in recent history. Network view of the market during the simulated flash crash.
