NZX, the only registered securities exchange in New Zealand, experienced a Distributed Denial-of-Service (DDoS) attack early this afternoon, which managed to briefly take it down.

Stock exchange operator said that the attack was a malicious attempt from overseas to disrupt normal traffic of the exchange's server with a flood of Internet traffic. NZX saw a spike in traffic this Tuesday at 15.57 and the number of connections attempting to reach its cash markets was enough to temporarily disrupt its activity.

A joint statement from the bourse and network provider Spark said the problem was resolved within an hour, and connectivity has now been restored. It also reassured the users that they will be able to use the platform normally on Wednesday’s session.

Spark’s technical support team spotted the attack and reacted 'quickly' to resolve the issue, said the spokesperson.

“Yesterday afternoon NZX experienced a volumetric DDoS (distributed denial of service) attack from offshore via its network service provider, which impacted NZX network connectivity. The systems impacted included NZX websites and the Markets Announcement Platform. As such, NZX decided to halt trading in its cash markets at approximately 15.57. A DDoS attack aims to disrupt service by saturating a network with significant volumes of internet traffic. The attack was able to be mitigated and connectivity has now been restored for NZX,” the company further states.

Despite the ongoing development in stock exchanges’ technical infrastructure and engineering staff, the latest incident reminds traders that access to even major platforms may become degraded or unavailable during times of significant  Volatility  Volatility In finance, volatility refers to the amount of change in the rate of a financial instrument, such as commodities, currencies, stocks, over a given time period. Essentially, volatility describes the nature of an instrument’s fluctuation; a highly volatile security equates to large fluctuations in price, and a low volatile security equates to timid fluctuations in price. Volatility is an important statistical indicator used by financial traders to assist them in developing trading systems. Traders can be successful in both low and high volatile environments, but the strategies employed are often different depending upon volatility. Why Too Much Volatility is a ProblemIn the FX space, lower volatile currency pairs offer less surprises, and are suited to position traders.High volatile pairs are attractive for many day traders, due to quick and strong movements, offering the potential for higher profits, although the risk associated with such volatile pairs are many. Overall, a look at previous volatility tells us how likely price will fluctuate in the future, although it has nothing to do with direction.All a trader can gather from this is the understanding that the probability of a volatile pair to increase or decrease an X amount in a Y period of time, is more than the probability of a non-volatile pair. Another important factor is, volatility can and does change over time, and there can be periods when even highly volatile instruments show signs of flatness, with price not really making headway in either direction. Too little volatility is just as problematic for markets as too much, we uncertainty in excess can create panic and problems of liquidity. This was evident during Black Swan events or other crisis that have historically roiled currency and equity markets.
