European Union Electricity Market Glossary

 

The necessity to indicate whether the counterparty to the trade is an "Aggressor" (A) or an "Initiator" (I) applies for the REMIT transactions and orders reporting purposes (Data Field No 12) when the trade was executed as an electronic or voice assisted trade on broker platforms.

 

"A" shall be indicated if the market participant was the originator of the transaction (aggressor) and "I" shall be indicated if the market participant was the passive participant (initiator), i.e. the one placing the order in the market first.

 

A buyer is identified as an aggressor if the market participant submits an order which matches with a sell order (initiator) that is already visible to the market place.
