FLASH CRASH

The growth of computer trading has brought tangible benefits to investors. Trading costs have decreased; complex information gets processed quickly and is included in financial instruments; markets have more water and are more accessible than ever before.

Not all sunlight, however. There are anxious markets that continue to be motivated by computer algorithms than any other underlying cause, leading to increased volatility and which can lead to instability or disruption.
It’s not all sunshine, however.

Flash crashes are when there is a sudden drop in prices for stocks, commodities, and bonds followed by a speedy recovery. It basically refers to a situation where the price of bonds, stocks, or commodities suddenly declines but then recovers quickly. It is known as a flash, as the market will suddenly collapse but prices will retain quickly. At the end of the day, the net effect seems to have been an accident with negligible effect. But if a light bulb is long enough to cause concern, it can destroy property and investors, it may scare consumers into buying less. At the wrong stage in the business cycle, it may just be enough to create economic ruin. High-frequency trading firms are said to be the main culprits in recent flashbacks.

Other causes of flash crashes include the use of a trading algorithm that can increase volatility and reduce liquidity. It is difficult to pinpoint exactly what is causing the flash crash. A variety of things can be set, but computer trading systems make any crash worse. These “bots” use algorithms that detect deviations, such as sales orders. They automatically respond by selling their catch to avoid further losses.

What causes Flash Crashes?

It is clear that inflation is not the result of bad news and bad news soon after. An important point to consider is that a crash could affect the entire stock index, not a single stock, bond, or asset. The cause of the crash is usually not due to a perceived change in the basic stock price.

One cause of flash crashes is caused by computer programs or algorithms. With the advent of trading techniques trading is becoming increasingly popular. Computers can capture enormous amounts of data and engage in high volume trading within minutes, without the human ability to make informed decisions. Some algorithms are designed to respond to sales pressures. When a global event, or a computer glitch, tells these programs that something unusual is happening, they automatically sell according to their code. These trading systems make any stock move more powerful, thus increasing the risk. For example, as more sales are done, compared to buying, algorithms start selling, too. This creates the effect of a snowball and the speed at which computers do business suddenly happens in the market.

High-frequency traders are one of the factors that are believed to cause or worsen flash accidents. These traders use algorithms to perform large transactions at very high speeds. Traders may deliberately use algorithms to engage in illegal activities such as fraud. For fraud, algorithms are designed to generate false sales. By simply placing an order for such a sale, prices are reduced, and sellers will be able to purchase at a reduced price. With algorithms, this process has been very successful and is now illegal. This is one of the ways in which algorithms can create market instability.

Recent Flash Crashes

2010 Flash Crash:

The May 6, 2010, crash, also known as the 2:45 crash or just a flash crash, was a catastrophe for the US stock market, which began at 2:32 p.m. EDT also lasts about 36 minutes. On May 6, 2010, U.S. stock markets reopened and the Dow was down and thus gone all day worrying about the debt crisis in Greece. At 2:42 pm, with Dow down more than 300 points a day, the stock market began to fall sharply, dropping another 600 points in 5 minutes with a loss of nearly 1,000 points a day at 2:47 pm. 20 minutes later, at 3:07 pm, the market again experienced a decline of 600 points. At the time of the flash crash, in May 2010, traders using high-frequency frequencies were taking advantage of the unintended consequences of merging US financial laws into Regulation NMS. The Wall Street Journal quoted the joint report as saying, “‘HFTs [then] start buying quickly and reselling contracts with each other – creating the effect of’ hot potatoes ‘as the same positions were shifted faster and faster.’ high speed “E-Mini price dropped by 3% in just four minutes” This flash crash was very important for a number of reasons. First, it was particularly noteworthy for the sharp decline in prices and was reported by many news outlets. Second, it brought attention to the role that computers can play in creating market instability and uncertainty.

2017 Ethereum Flash Crash:

On June 22, 2017, the price of Ethereum, the second-largest digital currency, dropped from more than $300 to $0.10 per minute on the GDAX exchange. Allegedly market fraud or initial bankruptcy, a recent GDAX investigation did not prove anything wrong. The crash was caused by a multi-million dollar sale that lowered the price, from $317.81 to $224.48 and caused the next $800 flood of suspension and limited funding orders, disrupting the market.

USDJPY and AUDUSD Flash Crash:

On January 2, 2019, a flash crash was seen in the USDJPY and AUDUSD stocks, which dropped by more than 4% in just a few minutes. It was a much lower USD rate compared to the Yen and AUD compared to the USD since March 2009. USDJPY and AUDUSD have acquired their maximum value over the next few minutes. It was thought that the flash crash may have been due to Apple reporting a drop in sales forecast in China but this seems unlikely as the report came out an hour before the actual crash. The low prices reported for USDJPY also varied with Reuters reporting a low price of 104.90 on USDJPY while FXMarketAPI reported a low price of 104.45.

Events described as flash crashes usually show a small or complete price recovery. On the other hand, the fast price falls in response to negative news that does not quickly return is often not seen as a flash crash.
