PropShop Taps Sterling as End of PDT Rule Reshapes Equities Trading

CHICAGO, IL – May 19, 2026 – Proprietary trading firm PropShop Trader is making a significant move into the equities market, selecting Sterling Trading Tech's advanced order management system to spearhead the expansion. The partnership, announced today, is a direct strategic response to monumental regulatory changes set to dismantle the long-standing Pattern Day Trader (PDT) rule, a shift poised to reshape the landscape for active traders and the firms that support them.

PropShop, a firm with deep roots in futures trading and known for its proprietary trading platform, has chosen the Sterling OMS 360 to build out its new equities division. The decision underscores a pivotal trend in the financial industry: as regulatory frameworks evolve, technology that provides real-time, pre-emptive risk management is no longer a luxury but a critical enabler of growth and compliance.

A New Era for Day Trading as PDT Rule Ends

For over two decades, the Pattern Day Trader rule has been a defining feature—and for many, a significant barrier—in the U.S. equities market. The rule, which designated traders making four or more day trades within five business days as PDTs, imposed a strict $25,000 minimum account equity requirement. This regulation effectively sidelined a vast number of smaller retail traders from actively participating in intraday stock and options trading.

However, this is all set to change. Following SEC approval, amendments to FINRA Rule 4210 will officially eliminate the PDT designation and its associated $25,000 minimum equity requirement, with the changes taking effect on June 4, 2026. This deregulation is expected to democratize access to day trading, potentially unleashing a new wave of market participants.

In place of the old regime, FINRA is introducing a more dynamic and technologically demanding "intraday margin" framework. Broker-dealers will no longer rely on a static, one-size-fits-all equity minimum. Instead, they will be required to monitor and manage risk exposure in customer margin accounts in real time. This new system calculates an account's intraday buying power based on its real-time margin excess, which updates dynamically as positions are opened and closed throughout the day. This shift places an immense responsibility on firms to have systems capable of preventing intraday margin deficits before they occur, a far more complex task than traditional end-of-day calculations.

PropShop's Strategic Pivot to Equities

For PropShop Trader, this regulatory sea change represents a prime market opportunity. The firm, which has built its reputation in the futures space with a unique model that shepherds traders through structured evaluation programs like its "Gladiator" and "Warrior" paths, sees a clear opening to apply its philosophy to a newly accessible equities market.

"Sterling’s strong reputation in the industry initially drew us in, but their onboarding process and team expertise quickly validated that decision," said Ashley Kozak, COO of PropShop. "Their team brings deep industry knowledge and approaches each client as a unique case, ensuring solutions tailored to specific needs. That level of customization and partnership truly sets them apart.”

PropShop's expansion is not merely about adding a new asset class; it is a calculated diversification strategy. By moving into equities, the firm can offer its traders a multi-asset environment, allowing them to leverage their skills across different market structures. The firm's claim to being the first proprietary trading firm to own its trading platform highlights a deep-seated belief in the power of technology, a belief that logically extends to its choice of partners for this critical expansion.

The Compliance Edge: Technology Enabling the Shift

The successful navigation of this new regulatory environment hinges entirely on technology. This is where the partnership with Sterling Trading Tech becomes central to PropShop's strategy. Sterling OMS 360 is specifically engineered for the complexities of the new intraday margin world.

Unlike legacy systems that rely on post-trade checks or partial controls, Sterling's platform provides native, real-time enforcement of both Reg T and Portfolio Margin requirements across the entire order lifecycle. This means that before an order even reaches the market, the system has already calculated its potential impact on the account's margin. If a trade would create a margin violation under the new FINRA Rule 4210 framework, it is blocked pre-emptively. This full lifecycle enforcement gives firms like PropShop the confidence to deploy sophisticated trading strategies in fast-moving markets without risking regulatory breaches.

"Sterling’s commitment to client service is backed by technology purpose-built to support the performance and financial objectives of proprietary trading firms," stated Jen Nayar, Sterling President and CEO. "We strive to anticipate client needs and deliver solutions that help firms operate with confidence in increasingly complex market environments. We look forward to supporting PropShop and their clients as they continue to grow.”

This proactive risk management is a significant competitive advantage. As broker-dealers and prop firms scramble to update their systems before the October 2027 final implementation deadline, firms that adopt compliant, real-time solutions early will be best positioned to capture market share and attract the influx of new traders.

Reshaping the Proprietary Trading Landscape

The PropShop-Sterling deal is a microcosm of a broader transformation within the proprietary trading industry, a market estimated to be worth over $12 billion. The days of firms specializing in a single asset class are fading. The modern prop firm is a multi-asset, technology-driven enterprise competing for talent in a global marketplace.

This evolution is fueled by several converging trends. First, the increasing accessibility of markets, accelerated by regulatory shifts like the end of the PDT rule, is expanding the talent pool. Second, traders themselves are becoming more sophisticated, demanding access to a wider range of markets—from futures and equities to forex and digital assets—all from a single, integrated platform. Finally, technology has become the primary battleground. The ability to provide ultra-low latency execution, advanced analytics, and, most critically, robust, automated risk management is what separates leading firms from the rest.

The partnership between a forward-thinking prop firm and a provider of cutting-edge risk technology illustrates the new blueprint for success. By leveraging Sterling's regulatory-aware OMS, PropShop is not just expanding its product offering; it is future-proofing its business model against a backdrop of profound and permanent market change.
