For each financial instrument, the aggregate number of orders and the volume they represent at each price level, for at least the five best bid and offer price levels.

Quote-driven trading system

A system where transactions are concluded on the basis of firm quotes that are continuously made available to participants, which requires the market makers to maintain quotes in a size that balances the needs of members and participants to deal in a commercial size and the risk to which the market maker exposes itself.

For each financial instrument, the best bid and offer by price of each market maker in that instrument, together with the volumes attaching to those prices.

The quotes made public shall be those that represent binding commitments to buy and sell the financial instruments and which indicate the price and volume of financial instruments in which the registered market makers are prepared to buy or sell. In exceptional market conditions, however, indicative or one-way prices may be allowed for a limited time.

Periodic auction trading system
