Episode notes
Edge Is The Core Currency
- Edge (expected value) is the single most important concept in trading and games.
- If you have a persistent advantage and manage risk, playing long enough yields outsized returns.
Training Through Poker And Mock Trading
- At SIG new hires were forced into daily poker and mock trading until midnight as part of culture and learning.
- The degenerate, immersive atmosphere accelerated practical skill and taught risk through play.
Learn Options By Total Immersion
- Immerse yourself intensely to learn options; treat it like a new language requiring total immersion for months.
- Use simulation, repeated mock trading, and timed reps to internalize chains and market mechanics.
