An order is the instruction to buy or sell a certain amount of a specific instrument. Orders of all sizes may be traded through Xetra®, as the minimum trading lot for Xetra® in Vienna has been defined as one for all segments except bonds. In bond trading, the minimum trading lot corresponds to the smallest tradable unit. The smallest tradable unit depends on the minimum denomination of the specific security (for example EUR 1,000).

Xetra® supports several order types, depending on the trading procedure, and all orders are all anonymous.

Continuous Trading and Auction

The following order types, validity restrictions, execution restrictions and trading restrictions are available:

Order Types

  • Market Order
    Unlimited buy or sell orders (orders to buy or sell at the best available price) to be executed at the next price that is determined.
  • Limit Order
    Limited buy or sell orders to be executed at the set limit price or better.
  • Market-to-Limit Order
    Characterized by an increased probability of execution (as market orders) combined with the security afforded by limit orders.
  • Iceberg Order
    Input of large order sizes into the order book during continuous trading without the market being given insight into the overall volume.
  • Stop Market Order
    When the stop limit is reached (or exceeded for stop buy orders or falls below it for stop loss orders), the stop order is automatically placed in the order book as a market order and may be executed immediately.
  • Stop Limit Order
    When the stop limit is reached (or exceeded for stop buy orders or if it falls below it for stop loss orders), the stop order is automatically placed in the order book as a limit order and may be executed immediately.

Validity Restrictions

  • Good-for-day
    Order is valid only for the current trading day.
  • Good-till-date
    Order is valid until a specified date (max. 360 days)
