Contract Specification

Strategy trading

IDEM provides members with specific types of orders that allow them to trade standard or tailor-made strategies.

Standard Combo Orders – standard strategy sent to the market as limit orders or market orders. Traders are not allowed to enter long-dated standard combinations since they are listed on a daily basis.

FLEXCO – functionality that allows members to structure, list and trade self-defined non-standard combinations involving different series and/or different underlying (belonging to the same market partition) with different execution ratios.

Traders can create and send Flexco to the market through a dedicated function that provides the member with simultaneous execution.

The functionality increases flexibility for traders in creating plain-vanilla (e.g price spreads, time spreads and straddles) as well as more complex and customized strategies. It also fully removes execution-risk for brokers: market participants are always confident to trade their combination at the desired price.

Since FLEXCO orders are listed on a specific order book but interact automatically with the individual legs of the strategy, they can be traded off according to two different ways.

For full details see the Instruction accompanying the Rules of the Markets organised and managed by Borsa Italiana


IDEM provides members with a specific functionality for block trading, allowing for reporting of large trades without market impact.

Members are allowed to send Cross and Committed orders:

  • Committed cross: the counterparty is a specific and predetermined intermediary
  • Internal Cross: both counterparties belong to the same member firm.

For Committed cross orders only, traders need to specify the code of their counterparty in order to match the trade. The central system keeps the trade report in a non-disclosed order book until the corresponding order with opposite sign is entered by the counterparty specified.

Committed cross and internal Cross orders can be traded through NORMAL or BTF execution:

  • Normal: the price needs to be within the best bid-ask spread at the time of the execution
  • Block-Trade-Facility (Btf ): if the order quantity is equal or higher to a minimum value defined by the Exchange, the execution price can be outside the best bid-ask spread. The quantity threshold and the maximum price divergence differ according to the product type.

Committed orders still not matched at the close of the trading session are automatically cancelled by the central system.

For the purposes of the automatic control of the regularity of trading and in order to preserve market integrity, Borsa Italiana defines the maximum size for normal orders, strategies and block trades.
