Chat With Traders

Stefan Stadie is a professional sports trader at Kero Sports whose work sits at the intersection of equities, sports betting, and prediction markets.

After starting his trading journey in equities, Stefan evolved toward a more process-driven approach focused on price, liquidity, and market behavior. Today, his edge comes less from predicting outcomes and more from identifying mispricing, capturing inefficiencies, and operating across multiple markets in real time.

In this conversation, Stefan shares how the same principles—crowd psychology, liquidity, and price discovery—show up across different environments, from stocks to sports to decentralized prediction markets. He also walks through his transition into arbitrage and market making,
how he approaches risk, and what it takes to stay disciplined when operating in fast-moving, competitive markets.

This episode offers a different lens on trading—one that challenges traditional thinking around prediction, edge, and where opportunity actually comes from.

In this episode, we explore:

·        Why trading principles can transfer across completely different markets

·        The role of liquidity and crowd behavior in shaping price

·        Moving from directional trading to arbitrage and market making

·        How mispricing creates opportunity across fragmented markets

·        The reality of being limited or banned by sportsbooks

·        Differences between traditional financial markets and emerging prediction markets

·        Managing psychology and discipline in fast-moving environments

·        Why focusing on price—not opinion—can change your approach to trading

About Stefan Stadie:

Stefan is a professional sports trader at Kero Sports, specializing in market structure, arbitrage, and market making. He also trades equities and participates in prediction markets, applying a consistent framework centered on liquidity, psychology, and price discovery across
different trading environments.

Sam Gaer’s career spans several major shifts in market structure — from the open-outcry pits of COMEX to high-frequency trading and now crypto derivatives.

Sam began his career as a teenage runner on the COMEX floor during the gold boom of the early 1980s before becoming a copper pit trader himself. While most traders relied purely on instinct, Sam was already experimenting with technology — building early pricing tools that helped identify inefficiencies in spread markets.

His path eventually led beyond the trading floor into exchange technology and market infrastructure, including building trading software that was later acquired by the New York Mercantile Exchange. In recent years, Sam has focused on crypto markets, where he applies traditional derivatives frameworks to volatility, options, and digital asset trading.

In this episode, Sam shares insights from decades of experience across multiple market regimes and discusses how trading edge evolves as markets and technology continue to change.

In this episode, we explore:

· Getting introduced to markets as a teenager

· Life inside the COMEX copper trading pits

· Early use of computers to price commodity spreads

· Inefficiencies in open-outcry markets

· Building exchange technology and selling Trading Gear to NYMEX

· The transition from pit trading to electronic markets

· Market structure lessons from traditional derivatives markets

· Why Sam shifted his focus to crypto markets

· Opportunities in crypto options and derivatives

· Convexity, volatility, and institutional trading frameworks in digital assets

About the guest:

Sam Gaer, Chief Investment Officer of the Directional Strategy at Monarq Asset Management, has more than three decades of experience across derivatives trading, exchange technology, and quantitative strategy development.

He previously served as Chief Information Officer of the New York Mercantile Exchange (NYMEX), where he helped modernize the exchange’s trading infrastructure. Earlier in his career, he was a floor trader on the COMEX commodities exchange and later founded
Trading Gear, a technology firm whose trading software was acquired by NYMEX. Sam has also launched and managed quantitative trading strategies focused on derivatives and volatility markets, and today works on institutional trading approaches within digital asset markets.

When Dave Mabe backtested his strategy, it outperformed his own discretionary trading — and changed how he approached everything. In this episode, we discuss gapping breakouts, expectancy, systematic trading, drawdowns, and the reality gap between backtests and live execution. A practical conversation for traders serious about building durable edge.

In this episode, we explore:

·        How Dave got introduced to markets: From early exposure to investing through his family to actively seeking more control over his capital and moving from swing trading into day trading.

·        Why rules matter: The transition from discretionary decisions to systematic frameworks — and why trading without a process is a fast path to inconsistency.

·        Backtesting as a “superpower”: What backtesting really does for strategy development and confidence in your edge.

·        Reconciling backtests with real life: Practical realities of execution, slippage, and market structure — and how to build a feedback loop so your live results get closer to your simulations.

·        Drawdowns and mindset: How to handle periods where a strategy doesn’t behave as expected, and why many traders quit in drawdowns rather than at all-time highs.

·        Scaling a trading business: The difference between scaling size versus scaling breadth — and why uncorrelated strategies matter.

·        Practical first step for systematic traders: How to start adding structure to your trading with backtesting, even if you’re not a programmer.

In this episode, Ian sits down with John Assaraf, entrepreneur, behavioral neuroscience educator, and founder of NeuroGym, for a conversation about the invisible forces that shape performance — long after planning, analysis, and good intentions are in place.

John shares his personal journey from a turbulent upbringing to building multiple multimillion-dollar businesses, and the pivotal moment at age 19 that reframed how he thought about success, identity, and commitment. From there, the discussion moves into the neuroscience behind habits, automatic behavior, fear, and why people often snap back to familiar results — even when they know what to do.

This is not a trading tactics episode. It’s a conversation about execution, follow-through, and the human side of performance — in trading, business, health, and life.

About the guest:

John Assaraf is a serial entrepreneur who has built multiple multimillion-dollar companies, including helping scale a real estate organization to over $4 billion in annual sales and co-founding a technology company that later went public on the NASDAQ. He is the founder
and CEO of NeuroGym, where he focuses on applying neuroscience to
performance, habits, and behavior change. John is also the author of several New York Times bestselling books, translated into dozens of languages, and has been featured in films such as The Secret, where many people were first introduced to his work.

Over the years, we’ve recorded hundreds of conversations with traders across different markets, strategies, and generations. And while no two
trading paths look the same, certain moments tend to repeat — not moments of big wins or dramatic calls, but quieter turning points. The moments where something shifts internally. Where progress depends less on the market… and more on how the trader evolves. In this special
episode of Chat With Traders, we revisit excerpts from past
conversations with traders who reached those inflection points — moments that reshaped how they thought about risk, discipline, accountability, and longevity. It’s a collection of turning points — the decisions, realizations, and hard lessons that changed the trajectory of a trading career.
