Introduction

This space is where I share my market insights and trading thoughts—from options structures like spreads and flies, to volatility regimes, risk management practices, and the psychology of positioning.

I aim to write in a way that is clear, structured, and practical:

  • breaking down complex market moves into simple narratives,
  • recording the reasoning behind trades, not just the outcomes,
  • and reflecting on lessons learned from both successes and mistakes.

Please note:

  • A basic understanding of options will help you follow along more easily.
  • If you’re new to derivatives, I recommend starting with some classic books:
    • Options, Futures, and Other Derivatives — John C. Hull
    • Options Volatility & Pricing — Sheldon Natenberg
    • Dynamic Hedging — Nassim Nicholas Taleb
    • Trading Volatility — Euan Sinclair

If you’re curious about how I approach options markets and trading discipline, I hope these notes will resonate and perhaps spark ideas for your own journey.
