NSE pre-open call auction session

Both the premier exchanges BSE and NSE are to kick off pre-open call auction section, soon. The pre-open call auction session will be for 15 minutes between 9 am and 9.15 am. The session would work as follows: The first eight minutes will be reserved for order entry, modification and cancellation, the next four minutes will be kept for order matching and trade confirmation. The remaining three minutes will be the buffer period to facilitate the transition from pre-open session to the normal market.

Initially, the call auction session will be applicable for Nifty-50 scrips and Sensex-30 scrips. More scrips will be gradually added to the list. Normal trading in other stocks will begin as at 9.15 am.

What is this pre-open session all about?

Indian markets have seen huge volatility, particularly during open trades. In the past few years, indices have hit the down circuit quite a few times and up circuit once. Call auction at pre-open will help arrive at a proper price, removing volatility and freak trades.

How does this order matching works?

In a Call Auction market, orders are gathered for execution at predetermined times when the market is called. At the call, all buy orders are aggregated into a downward sloping demand function and all sell orders are aggregated in an upward sloping supply function.The logic of order batching which is core to the Call Auction mechanism is well explained here.

Call Auctions across the world have been applied to various sessions during the trading day at the Open, Close and during trading halts. So, hopefully no more freak trades of abnormal highs and lows.

Team Work - Meaning and Tips for better Team Work

A single brain is not always capable of making key decisions on its own. To come up with an efficient solution, an individual requires the help and advice of others. A team is established when individuals get together on a common platform with the common goal of completing a task. To guarantee optimum compatibility, team members should ideally come from similar backgrounds and have a single aim. To provide their best, the team members must complement each other and function as a single unit in tight cooperation. "There is no I in Team Work," as the saying goes, and each member must put the needs of his team first. Personal interests must take a second seat. Any team's performance is directly proportionate to the relationship between its members and their combined efforts. What is the definition of teamwork? Teamwork is defined as the sum of each team member's efforts toward the fulfilment of the team's goal. In other words, any team's backbone is its ability t

Scientists discover a new theory / The fundamental property of light – 150 years after Maxwell

Light plays a vital role in our everyday lives and technologies based on light are all around us. So we might expect that our understanding of light is pretty settled. But scientists have just uncovered a new fundamental property of light that gives new insight into the 150-year-old classical theory of electromagnetism and which could lead to applications manipulating light at the nanoscale. It is unusual for a pure-theory physics paper to make it into the journal Science. So when one does, it’s worth a closer look. In the new study, researchers bring together one of physics' most venerable set of equations – those of James Clerk’s Maxwell’s famous theory of light – with one of the hot topics in modern solid-state physics: the quantum spin Hall effect and topological insulators . To understand what the fuss is about, let’s first consider the behaviour of electrons in the quantum spin Hall effect. Electrons possess an intrinsic spin as if they were tiny spinning-tops,
