Some experts put forward an unexpected version about the "Black Monday", August 24, 2015, when the world suffered the largest drop in stock markets in recent years. In their opinion, robots-traders are to blame for the collapse.

The reason for the analysis glitch is that at the moment robots are responsible for half of the stock trades. The principle of smart computers is such that they trade with unprecedented speed and in large volumes. At the same time, a number of market segments are connected by one strategy, that is, when a machine can not buy or sell assets in one segment, it goes to another one, and since algorithms are similar, a kind of computer crash is formed in the markets.

Such turmoil leads to a dishonest stock market game, since large traders, at whose disposal there are computers for high-frequency trading, claim record profits, and investors, who are at a level well below, lose orders. The collapse of August 24 was also provoked by the actions of high-frequency traders.

Experts believe that robot traders significantly change the market. Of course, their role is great and no one will refuse the robot's help, but it is very difficult to predict how computers will behave in the future in similar situations. Such exchange jumps, which "Black Monday" demonstrated, have become an integral feature of modern markets, which are partially controlled by robots.
