Mastering Uncertainty: The Options Arm
By Nadine Yip
Is there more to an exchange than straight trading assets?
Every other arm trade assets head-on. The Options Arm adds a new dimension — options, contracts giving the right (not obligation) to buy or sell a stock at a set price. This is where teams trade volatility and probability rather than pure direction.
It connects straight back into the rest of QTE, where options here are built on the same underlying stocks traded elsewhere. The arm mirrors the existing structure, with 3 market-making teams continuously quoting options and hedging by trading the underlying stock, while 3 market-taking teams hunt for mispricings and volatility opportunities, just like their counterparts in the Market Taking Arm. The catch? Takers here can only trade in markets created by QTE's own makers, keeping the arm a closed arena of strategy.
Each team has 7 students: a Team Head leading strategy and making final calls, four Quantitative Analysts pricing options, analysing volatility, and managing risk, and two Software Developers building the pricing and risk tools behind them. The roles are shared but the focus differs, where market-making teams quote competitive prices and manage inventory risk as volatility shifts, while market-taking teams hunt for pricing inefficiencies to trade on.
Trading is limited to single-stock options and index options. Market makers are each assigned a smaller slice of that list, forcing tight quotes on fewer names instead of thin coverage across many. Market takers can trade any stock on the list, but only on markets the market makers create, keeping the competition contained within the arm.
Each contract is defined by underlying stock, option type, strike, and expiry. Both calls and puts are available on every stock. Strikes sit close to the current stock price, with a limited range of in-, at-, and out-of-the-money levels, and all contracts share the same size and cash settlement.
Teams are ranked on two metrics which show how often trades are profitable versus not. And as with all the other arms, guardrails are used to keep the exchange realistic. This includes capital caps, position limits, and exposure thresholds, pushing teams to think like professionals. Push too far and you’re cut off; play too safe and you miss the move. These boundaries ensure teams manage volatility responsibly by learning to balance risk and reward.
The Options Arm runs on a streamlined trading interface. Each team is equipped with a live dashboard showing prices, positions and risk in real time. Market quote and adjust spreads across calls and puts, while market takers trades directly against these quotes. The system includes special features like an options ladder for quick visibility of strikes and expiries, and volatility charts for deeper analysis. Each feature is uniquely tailored so teams can act with clarity, speed and control.
The Options Arm is where students learn to think in four dimensions: price, time, volatility and risk. Flowing in tandem with the other arms, options trading adds depth to the exchange by turning uncertainty into opportunity.
