EP3® Update Highlights March 31, 2025 

We are continually enhancing the functionality and performance that EP3 offers exchange operators. In response to customer feedback, EP3 now supports the following:

Improved Performance Observability

EP3 now produces additional Prometheus metrics that allow exchange operators to monitor and alert on end-to-end performance of order entry. These metrics measure the time from order arrival at the FIX Gateway to the publication of the FIX execution report acknowledging the order. 

Dependent Services Health Checks

All EP3 services implement the gRPC Health Check Interface. This allows developers utilizing any EP3 API to first determine the health of dependent services prior to interacting with the API. 

Performance Updates

Several performance updates were made to EP3 and EP3 components during March including: the reduction of message size on the critical path to decrease message bandwidth and increase throughput, updating of decimal libraries to increase order entry throughput and performance, improved the time to recover services when there are large numbers of users and accounts present in EP3, and improved database query performance.

Banking Service Enhancements

The Banking Service manages deposit and withdrawal workflows between EP3 and commercial banks. Several functional enhancements were made including making it easier for Exchange Operators to verify cash held in a commercial bank account versus the value recorded in EP3.

Trading API Update

Exchange Operators can now implement manual or automatic order approval workflows by previewing orders before submission  to the matching engine.

Introducing the EP3® Trade Clearing API

Today, Connamara Technologies announces the release of the new Trade Clearing API for EP3

An exchange using a central limit order book is responsible for managing the transaction that occurs when the price of a buy order matches that of a sell order. What happens next, post trade, is the clearance and settlement of the trade. This is, among other things, where the buyer transfers the funds used to buy the asset to the seller, and the seller transfers the purchased asset to the buyer. This process is loosely called Trade Clearance and Settlement.

While EP3 does provide the functionality for the clearance and settlement of trades made in the EP3 matching engine, some Exchange Operators choose to use third-party clearing and settlement services for this process. 

Because EP3 offers the Trade Clearing API, Exchange Operators can create the workflows and interactions necessary to utilize the services of third-party clearing providers.

The EP3 Trade Clearing API allows exchange operators to interact with third-party clearing platforms by: 

  • Reporting to the clearing platform
    • New transactions and block trades made on EP3
    • The cancellation of previously reported trades
  • Receiving reports from the clearing platform of
    • Trades that have been rejected by the clearing platform
    • Cleared volumes and open interest for instruments traded on EP3

At Connamara Technologies, we continually strive to improve how our customers interact with the EP3 platform. A key pattern we put in place when we first designed EP3 was to allow our customers to interact with the functionality and data within EP3 via a set of well-defined and easy-to-use APIs.

EP3® Update Highlights February 24, 2025 

We are continually enhancing the functionality and performance that EP3 offers exchange operators. In response to customer feedback, EP3 now supports the following:

1. Halt all markets from Admin UI

Exchange Operators can now halt all the markets open on EP3 with a single button click. This gives the exchange operators more control over their markets. For those customers that design and implement their own custom user interfaces and workflows this functionality is also available via an EP3 API endpoint. 

2. Admin UI White Labeling

Exchange Operators can now white label the EP3 Admin UI with their company’s custom logo, color palette, and tag line text. The logo is displayed at the top of the navigation bar and also serves as the favicon for the page.

3. Account Product Level Open Position Limits 

The open position limits for participant accounts can now be set at the Product Level in addition to the Instrument Level. This improves operational efficiency for those Exchange Operators that have large numbers of instruments that are of the same product. The limits can be set manually using the EP3 Admin UI or automated via an API endpoint. 

4. Enhanced Commission Flexibility

Updating EP3’s powerful rule-based commission model, exchange operators can now create a rule to apply a commission only to certain account types or a rule to exclude a commission from applying to certain account types.

5. Various Performance and Reliability Enhancements

The team at Connamara Technologies is always looking to improve the already high performance and reliability of EP3. This includes both pre-trade order entry and the often overlooked post-trade processing. 

  1. Improvements in post-trade reporting of trades when customers experience a spike in the number of trades per second.
  2. Improved database resilience and data integrity during failover.
  3. Increased the performance of the EP3 Order Routing FIX API by removing message logging from the critical path for order entry.
  4. Improved the performance of the service that evaluates the outcome of an event contract to determine the winner.

Introducing the EP3® Back Office API

Today, Connamara Technologies announces the release of the new Back Office API for EP3

Exchanges that receive or distribute funds need a means to access the records of that activity for downstream workflows for reporting, account reconciliation, or audits. 

These downstream workflows can be implemented using third-party applications or applications built by the exchange operator’s in-house team. 

Because EP3 offers the Back Office API, exchange operators can integrate with third-party accounting systems and create applications and workflows bespoke to fit the specific needs of the back office and accounting teams of the exchange. 

The EP3 Back Office API allows exchange operators to: 

  • Get all deposits for an account over a date time range
  • Get all withdrawals for an account over a date-time range
  • Integrate with third-party accounting systems to create journal entries for account deposits and withdrawals
  • Create reports to show:
    • The amount in trading commissions a participant firm earned over a period of time.
    • The amount in trading commissions an exchange clearing member firm earned over a period of time.
    • The amount of exchange fees an exchange earned over a period of time.
    • The amount of clearing fees an EP3 clearing house earned over a period of time.

At Connamara Technologies, we continually strive to improve how our customers interact with the EP3 platform. A key pattern we put in place when we first designed EP3 was to allow our customers to interact with the functionality and data within EP3 via a set of well-defined and easy-to-use APIs. 

Learn more about the EP3 Back Office API.

Introducing the EP3® Settlement Price API

Today, Connamara Technologies announces the release of the new Settlement Price API for EP3

Regulated derivatives and other exchanges may be required to set a Daily Settlement Price for each contract, along with a Final Settlement Price when the contract expires. The setting of these prices is crucial as in many cases, it will trigger the transfer of funds between exchange participants. 

While setting a settlement price is ubiquitous, the method used to determine its value can vary significantly between different asset classes and exchanges.

Because EP3 offers the Settlement Price API, exchange customers can implement a bespoke settlement price calculation strategy – tailored to their asset classes and the market they are serving. 

The EP3 Settlement Price API allows EP3 exchange customers to: 

  • Access pricing data of assets traded by the exchange on EP3
  • Create a custom settlement price calculation and approval workflows
  • Set the Daily and Final Settlement Prices for assets traded on their exchange

At Connamara Technologies, we are continually striving to improve how our customers interact with the EP3 platform. A key pattern we put in place when we first designed EP3 was to allow our customers to interact with the functionality and data within EP3 via a set of well-defined and easy-to-use APIs.

EP3® Update Highlights January 21, 2025

We are continually enhancing the functionality and performance that EP3 offers exchange operators. In response to customer feedback, EP3 now supports the following:

Maker / Taker Fees / Commissions

EP3 already has a robust, rules-based commission structure that allows customers to set trade commissions in several ways. Exchange operators can now set up a Maker/Taker Commission schedule to encourage exchange users to rest liquidity in the market, such as offering rebates (negative commissions). 

Product Level Commissions

Commissions can now be set at the Product Level, which benefits exchanges that list a large number of related instruments. This new feature improves exchange operators’ operational efficiency. 

Improved Scalability, Availability, and Fault Tolerance of the EP3 Instrument Server

The EP3 instrument server provides details on the tradeable instruments in EP3 and manages their trading schedules. Think of it as a security master. The latest enhancements allow the EP3 Instrument Server to be deployed in a multi-replica configuration, leveraging Kubernetes for scale, load balancing, and fault tolerance.

Corporate Actions Support

Customers have requested that EP3 provide support for certain corporate actions. EP3 now offers new functionality for stock splits and dividends. Via the EP3 Admin API, exchange operators can indicate that a corporate action is in progress, which will be communicated to market participants over FIX market data. Stay tuned for more updates to this functionality.

Connamara Tech’s Birthday: Three Lessons We Learned in Three Years

Connamara Technologies was founded in the winter of 2022. Three years later, we are on a trajectory we couldn’t be more proud of. As we reflect on our nascent stage, servicing the innovation goals of a sharply growing list of global clients, we’d like to take a moment to share the lessons we’ve learned along the way. 

To gain a deeper understanding, I contacted our team members and encouraged them to reflect on their experiences scaling and growing the EP3® matching engine and platform. After reviewing this feedback, I could not help but share their assessment of the last three years and our biggest takeaways. Their insights offer a collective perspective on the knowledge we have gained throughout our remarkable journey.

A Product Company Operates Differently Than a Services Company

Connamara Technologies grew out of our custom capital markets software development company, Connamara Systems, which has successfully delivered custom technology solutions for twenty-six years. Moving into the product space with EP3® required us to adopt a new way of thinking.

Building a product like EP3 demands a focus on scalability, standardization, and long-term roadmaps. We found that our historical experience in building bespoke solutions for our legacy clients was a double-edged sword when trying to build a product company. 

When building software tailored to individual customer requirements, the default behavior is to create whatever the customer wants. 

When building a product that serves a diverse market, you need to take a beat and evaluate each customer request against the product roadmap and the value of the change in terms of the product-market fit. Yet, our deep experience building custom solutions for clients gave us a unique edge—understanding how to listen to clients and respond to their diverse needs in an evolving landscape. Learning to balance these two worlds has been a challenge but ultimately a key to our success.

Innovation Comes From Customers

While we’ve recently invested in formal market research in our collaboration with Acuiti, some of our most groundbreaking ideas for our EP3 matching engine have come from simply listening to our customers. 

Our diverse customers’ feedback, insights, and challenges have been invaluable in shaping and driving our innovation strategy. This is because our customers always push the envelope when developing new exchanges and marketplaces. Whether our customers have brought us a twist on the digital asset marketplace, a plan for a new exchange in an emerging economy, or an idea that’s never been attempted before in the current marketplace, we’ve grown with our clients to meet their expectations and evolving needs.

Great Documentation is as Valuable as Great Code

Clear, thorough documentation helps customers implement and use EP3® effectively, reduces onboarding friction, and provides valuable support. This allows us to spend more time working with our customers on complex problems and solutions, rather than questions that have been answered previously. By the same token, excellent documentation allows our customers’ operational and technical teams to be more efficient, thus lowering the total cost of ownership of EP3. Documentation is an investment that continues to pay dividends long after the code is written for the vendor and the customer alike.

As we celebrate our third anniversary, we’re excited to carry these lessons into the next chapter of our journey. Thank you to our customers, board, and team members for helping make these three years so impactful. Here’s to continued innovation, collaboration, and growth in the years ahead!

James Downs,

Co-Founder and CEO

Four Key Functionality Upgrades EP3 Delivered in 2024 

Last year, Connamara Technologies made significant strides in improving EP3, not just in performance—enhancing reporting speeds, pre-trade risk, scalability, and transaction throughput—but also in functionality.  By analyzing the ever-evolving landscape of the exchange world, staying on top of what innovators need most, and building features through our discovery process, we made immense expansions to our matching engine product and platform’s capabilities.

  • 24/7/365 Exchange Support: Updated Trade Date functionality and end-of-day market actions, making it easier for exchanges to operate continuously.
  • Bulk Settlement Price Management: Simplified end-of-day workflows by enabling operators to bulk upload and approve settlement prices.

Advanced Risk and Compliance Management

Risk management and regulatory compliance remain at the core of EP3. This year, we delivered several impactful upgrades:

  • Omnibus Account Support: Helped Futures Commission Merchants (FCMs) manage accounts more efficiently.
  • Position Limits: Introduced account-level limits to enhance pre-trade risk management.
  • Pre-Trade Risk for Event Instruments: We have added support for Binary and Continuous payouts, empowering customers to design creative event contracts.

Spotlight: How EP3® Powers BEE4’s Brazil’s First Regulated Tokenized Stock Market

In this Connamara Technologies Spotlight, we highlight how EP3 technology powered BEE4, Brazil’s first regulated tokenized stock market. Patricia Stille, CEO and Co-Founder, Rodrigo Fiszman, Co-Founder and Chairman, and Paloma Sevilha, Head of Products, speak on BEE4’s innovative trading platform and how our matching engine, our customized approach, and our support services allowed their technology to thrive. The full Case Study on our work with the Sao Paolo company illuminates how BEE4 leveraged Connamara Tech’s APIs to customize their exchange precisely to their specifications, adapting certain rules to align with the Brazilian market.


We chose Connamara’s solution after evaluating other providers across the globe. This is the kind of partnership that is key: not only to develop the SME segment but also to expand to other niches and scale up.

Patricia Stille, CEO and Co-Founder of BEE4

Transcript:

Patricia Stille, CEO and Co-Founder of BEE4: BEE4 is a pioneering OTC market in Brazil focused on SMEs and one of the first initiatives globally using blockchain and regulated market infrastructure. With the creation of this new market, SMEs can gain access to capital markets, fund their expansion strategies, and improve their visibility. At the same time, clients can benefit from IPOs and trade shares of high-potential firms typically unavailable in traditional exchanges.

Rodrigo Fiszman, Co-Founder and Chairman: BEE4’s trading model has a weekly auction with tunnel prices, so, at the end of the day, you can only put orders and input a trade between the tunnels in the auction. Since we’re talking about small and medium companies with less liquidity, we were focused on reducing the volatility for the owners, entrepreneurs, of those companies. BEE4 received its license in September 2021. From that day ’till one year after we launched, we were able to have more than 6,000 investors in our trading venues. We had four IPOs in a period when you didn’t have any IPOs in Brazil.

Paloma Sevilha, Head of Products: Connamara Technologies is the company behind EP3. EP3 is the order-matching engine and the exchange trading platform behind BEE4 operations and other exchanges worldwide. We chose EP3 for a few reasons. First of them, they are a well-established exchange platform. Second reason, they were very open to building these new features with BEE4. And third, they were part of the project regarding the FIX protocol which is something that is crucial for business. EP3 is very asset-neutral. And in BEE4 we work with tokenized stocks. And, we’re planning to work with different assets. We can have all these assets in EP3. We can just create a product and we can build that in a few minutes just with a few clicks. Besides that, we have the Connamara support team that is available 24/7. We work from 10 a.m. to 8 p.m., so we do need a team that is available for longer hours in case there are any bugs or any questions or any maintenance needed. They’re there and they answer really quick.

Rodrigo Fiszman, Co-Founder and Chairman: So, in the end of the day, having Connamara as a partner and using EP3, it was all about scalability and also leveraging ready-made solutions that allow us to gain a head start.

Patricia Stille, CEO and Co-Founder of BEE4: We chose Connamara’s solution after evaluating other providers across the globe. This is the kind of partnership that is key: not only to develop the SME segment but also to expand to other niches and scale up.
