Ex-Citadel Trader Sean Gong Promotes Institutional Trading Strategy Service

By

1d ago· 2 min readen

Summary

This is a promotional piece for a service offered by an ex-Citadel options trader named Sean Gong. It presents a framework for building trading strategies by thinking like an institutional market-making desk. The framework focuses on two key questions: whether a trading edge is real (and why the market hasn't already exploited it), and how to determine position sizing using the formula Position = Edge / Variance. The article is essentially an advertisement for a service where users can open a live Interactive Brokers line to pressure-test trades against institutional desk thinking.

I'm here for one thing: helping you build a robust trading strategy — by running your idea through the way the market-making desk on the other side thinks.
Is the edge real? Where do you think the price is wrong? And why hasn't the market already taken the opportunity? If the reason's obvious, the 'edge' is usually someone on the other side knowing more than you.
How big should you go? Not gut feel — the desk answer is Position = Edge / Variance: bigger when the edge is
