![]() Note that in 2019 caps had already been placed on dark trading under the EU’s Market in Financial Instruments Directive (MiFID) II (see here and here). European dark pools accounted for 9.1% of all European on-exchange activity in April 2019 and for 9.6% in July 2019. This need has never been more critical than now as dark trading currently enjoys high prominence in developed markets. Understanding these dynamics, and specifically, what drives trading volume to dark pools, is critical for the determination of the effects of dark trading on market quality. A lack of pre-trade transparency suggests that dark pools impair price discovery, and this perception has led to efforts to increase disclosure and curb trading in dark pools in several countries, including Australia, Canada (through price improvement rules), and in Europe (through the imposition of volume caps).Īt the heart of the impact of dark pools on market quality are the dynamics of trading venue selection in financial markets. At first glance, the scepticism appears valid. A survey conducted among market participants by the CFA Institute found that 71% of respondents are of the view that dark pools constitute problems for price discovery in the markets (see Schacht et al. In 2010, the US Senator Kaufman, in a letter to the then SEC Chair Schapiro, calls for actions to “examine whether too much order flow is being shielded from the lit markets by dark venues”. Stakeholders are especially concerned about the effects of the lack of pre-trade transparency. The debate on the usefulness or the market quality imperativeness of these type of venues is a long-running one. This means that one can submit an order to such an exchange without anyone being the wiser until the order has been executed. The current market cap of VXX is around $800 million.Dark pools, such as Turquoise Plato (previously Turquoise Midpoint Dark), are trading venues that do not offer pre-trade transparency. ![]() These ETNs were made available for volatility trading in the United States just like any other stocks (prospective here).* They can be sold, bought, or sold short whenever the market is open for trading, and that includes both pre-market and after-market timeframes. In 2009, Barclays created two of the earliest volatility ETNs – VXX and VXZ (its sister fund). To properly understand what VXX is, you need to understand how its value is assessed, and how Barclays (Britain’s foremost multinational banking and financial services company) earns equity from running it, and what it actually tracks. VXX and VXZ (its sister fund) were the first ETNs (Exchange Traded Notes) made available for volatility trading in the United States. To do that, you need derivatives – like futures and options, spread betting or CFD trading. You can not trade the VIX index directly nor can you trade volatility directly like you trade stocks. ![]() SPX is a broad measure of the US stock market which tracks the top 500 listed US companies. The VIX index is based on the options on the S&P 500 Index (SPX), the most-watched US equity index. VIX futures were created around 2004 to facilitate trading and hedging of volatility and are based on the VIX index.
