HUPX DAM (Day-ahead Market)
The HUPX Day-ahead Market enables trading of hourly and block-based electricity products for next-day delivery. Its goal is to ensure efficient competition and high liquidity, supporting the optimal use of energy resources. At the core of the market is an algorithm that considers transmission constraints and aims to maximize social welfare.

HUPX IDC (Intraday Continuous Market)
The Intraday Market aims to bring electricity trading as close in time as possible to actual delivery. Recognizing this need, HUPX launched the IDM on March 9, 2016. The market provides participants with flexibility to adjust to real-time system conditions and supply-demand dynamics.

HUPX IDA (Intraday Auction Market)
The Intraday Auction Market is a form of intraday trading conducted through scheduled auctions. Its purpose is to enable the pricing of transmission constraints that cannot be addressed in continuous trading. IDA contributes to more efficient market operation and greater predictability in electricity trading.

As Hungary’s power exchange and a licensed NEMO under MEKH, HUPX plays a central role in advancing market coupling within the European electricity sector.

What is Market Coupling?

Market coupling (implicit capacity allocation) is a key mechanism used in the European electricity market to efficiently allocate cross-border transmission capacity while optimally matching electricity supply and demand across different countries. Applying this approach, HUPX—together with all the other European NEMOs and TSOs—connects cross-border electricity markets via:

• Single Day‑Ahead Coupling (SDAC): Using the EUPHEMIA/PCR algorithm to efficiently match bids across borders in one auction.
• Single Intraday Coupling (SIDC): Real-time, continuous market operation across borders, facilitated by the XBID framework

Market coupling helps integrate national electricity markets into a unified European market, aiming to:

• Maximize the use of cross-border transmission infrastructure
• Ensure electricity flows from low-price to high-price areas
• Increase competition and liquidity
• Lower costs and improve price convergence
• Facilitate renewable energy integration

How does it work?

NEMO 

The HUPX Organized-Market Committee is an independent body of HUPX, that was established in order to ensure the state of art governance rules.

The Organized-Market Committee is a body elected from the representatives of the HUPX Members. It has an advisory role in the process of decision making on the Rules and Regulations and on general decisions related to the HUPX Market, the Hungarian organized electricity market.

The list below contains all independent software vendor (ISV) companies, which provide software with real-time interface to HUPX Intraday trading system (M7) through API. The following access types can be requested:

• read only: retrieve market and trading data on real-time basis;
• read & write: retrieve market and trading data on real-time basis and possibility to submit orders.

The listed software are certified by HUPX following the successful completion of operational tests.

Useful information for our members and prospect members: in case you use the software of one of the registered ISVs, you can request for an M7 API access without passing a preliminary conformance test.
