Episode notes
Single-Tick Levels Beat Wide Zones
- Single-tick key levels pinpoint where statistical imbalances between buyers and sellers exist.
- Dr. Levy intersects these levels across correlated instruments to raise trade probability.
Require Correlated Confirmation
- Trade only when multiple correlated assets hit their key levels simultaneously to avoid coin flips.
- Require agreement from three assets and ensure the fourth does not contradict before entering.
Time Entries To Minimize Drawdown
- Prioritize timing entries to minimize drawdown rather than moving stops aggressively.
- Use a constant tight stop for catastrophes and time entries so stops rarely get hit.
