Proper as much as about 9:18 a.m. ET, all 4 exchanges and the ETX reference fee are transferring in sync, in what appears to be like like a reasonably regular ether value dip. The rising dimension of the bubbles represents bigger and bigger trades as merchants react to the worth motion, a technique or one other. At 9:18 a.m., the Kraken market, represented in yellow, immediately crashes severely.

Kraken’s CEO has said the Kraken ETH flash crash was not the results of a technical glitch. As the next three charts will present, nonetheless, two comparable ETX part exchanges dealt with comparable will increase in quantity simply high-quality, together with the often lower-volume ETH-USD market on Bitstamp. The ETX incorporates solely executed trades, not orders.

Have been there different giant trades? Sure. At 9:18 a.m. ET, because the Kraken ETH flash crash started, Kraken dealt with 13 trades in quantity of fifty ETH or higher. That’s considerably extra giant ETH trades than some other market at the moment. Nevertheless, it wasn’t the best rely of enormous ETH trades on the morning of Feb. 22. At 8:52 a.m. ET, Bitstamp printed 14 transactions of fifty ETH or extra. By 9:29 a.m. ET, Kraken would match that quantity, presumably as arbitrage merchants took benefit of the still-wide unfold between costs printed on Kraken and the remainder of the market, as represented by the ETX. 

As famous above, the ETX counts solely executed trades. That is to stop manipulation of the reference fee by means of order-book actions like “spoofing,” a sort of manipulative exercise through which merchants place disingenuous orders, to simulate demand. If it’s order-book evaluation you’re on the lookout for, Kaiko has a good breakdown of the Kraken ETH flash crash, alongside these traces. 

Kaiko didn’t discover any conclusive proof as to what brought about the crash, both. Whether or not it was a technical glitch or a sudden run on the order guide in all probability doesn’t matter. With value discovery happening on a number of venues, know-how threat is multiplied and liquidity is split. Till capital is ready to circulate extra freely into these fragmented markets, buyers ought to count on extra flash-crash occasions.
