The 'Flash Crash' of 2010 explained: Lessons for Forex Traders

On May 6, 2010, the financial world watched in disbelief as the Dow Jones Industrial Average plummeted nearly 1,000 points in a matter of minutes, only to recover those losses shortly thereafter.


This event, known as the 'Flash Crash,' highlighted the vulnerabilities and complexities of modern financial markets, including the Forex market. As we approach the 14th anniversary of this pivotal moment, it presents an invaluable opportunity for traders to reflect on the lessons learned and how they can be applied to Forex trading. Join us as we delve into the 'Flash Crash' explained.

This article delves into the 'Flash Crash,' explains its causes, who was responsible, the consequences they faced, the consequences on the trading market, and the preventative measures now in place.


Understanding the Mechanisms Behind the Flash Crash of 2010

The SEC conducted an extensive investigation into the 2010 Flash Crash, delving into transactions executed in milliseconds. The catalyst was identified as a fundamentalist trader who issued a Volume Weighted Average Price (VWAP) automated SELL order for S&P500 e-minis, instead for a Time Weighted Average Price (TWAP) order.

VWAP calculates the average price based on volume and can initiate sell or buy orders during volume surges, without considering time. In contrast, TWAP factors in both time and price for its triggers.


During this period, the e-minis market was already facing downward pressure, with sell orders outnumbering buys. The misapplied VWAP order exacerbated the situation, increasing the selling volume and speed significantly.


This led to a domino effect, as the rapid selling of e-minis spilled over into the S&P500, causing widespread sell-offs within minutes. Automated stop-loss orders were triggered, and prices of many S&P500 stocks nosedived at unprecedented speeds. The automated systems eventually paused trading for numerous major companies to stem the tide, but not before significant losses occurred, with some stocks dropping by 50-70%. Ultimately, the situation was largely rectified as orders were reversed due to systemic failure, but not without severe repercussions.

Who caused the Flash Crash?

The individual responsible for The Flash Crash was a Mr Navinder Sarao, who traded from a bedroom in his parents’ west London home. Mr Sarao was arrested in 2015 and pleaded guilty to illegally manipulating the stock markets with trades that led to one of the most dramatic crashes in history. It was alleged that Sarao earned more than £45m ($70m) in trading profits from his scheme – of which at least “$12.8m was attributable to his fraud and spoofing scheme”. He initially faced 22 charges, which carry a maximum sentence of 380 years. However, it is reported that prosecutors decided not to push for a jail sentence, mainly due to the fact Sarao didn't spend the money he gained from his fraudulent activities on any luxuries and he quickly lost his windfall to fraudsters.

Market Liquidity and Risk Management

The flash crash brought the issue of market liquidity to the forefront. In volatile markets, liquidity can evaporate quickly, leading to drastic price movements. For Forex traders, understanding liquidity and incorporating strong risk management strategies, such as setting stop-loss orders and diversifying trading approaches, is crucial in mitigating risks associated with sudden market movements.

Regulatory Responses and Market Safeguards

In the aftermath of the crash, regulatory bodies implemented several measures to prevent similar incidents. These included the introduction of circuit breakers, which temporarily halt trading in response to extreme volatility. For Forex traders, staying informed about these safeguards and understanding their implications is essential for navigating the market effectively.
