Trading system

Since November 17, 2000, quotations on the Warsaw Stock Exchange have been taking place in the WARSET system (WARsaw Stock Exchange Trading system).

In each of the WARSET quotation systems, the transaction unit is one security. A characteristic of WARSET is publication of the so-called Indicative Opening Price (IOP) during the pre-opening, pre-closing and balancing phases. This is the price of a security calculated for a given moment. At the moment of opening, i.e. determination of the first price (the last price in the case of the closing phase), the price at which the first of these transactions is concluded is the last published IOP.

In establishing the price of a given security, the following objectives are taken into account:
a) maximisation of trading volume,
b) minimisation of the difference between the numbers of securities in sell and buy orders possible to execute at a given price,
c) minimisation of the difference between the determined price and the reference price.

On July 12, 2010 NYSE Euronext (NYX) and the Warsaw Stock Exchange (WSE) announced the establishment of a strategic, long-term cooperation agreement. As part of a multi-year commercial agreement, NYSE Euronext will provide WSE with the Universal Trading Platform for its cash and derivative markets.
