RED LINE methodology
How to read the Ledger
Five minutes and you can read the full board. Signals are observations from tested rules by price band, not financial advice.
The Ledger in 10 seconds
Simple meanings first, then details below.
Green stamp: the data likes this setup in this band.
Red stamp: weakness is active, plan your risk.
Hold: no edge right now. Waiting is a decision.
Stamp signals
What each stamp means and what to do with it.
The data says this card is in a buy-favored setup for its price band.
What to do: If you were already considering entry, this is a data-backed moment to review position size and risk.
No strong edge is active right now.
What to do: Do not force a move. Wait for a better setup.
Weakness is showing and similar setups often kept falling.
What to do: If you hold the card, decide your exit plan now instead of after another leg down.
Early rebound behavior after a damaged trend.
What to do: Treat as speculative: smaller size and tighter risk control.
Supply-pressure buy signal from listings and trend behavior.
What to do: Use as an early heads-up and monitor confirmation.

Liquidity context

Deeper listing environment and typically faster execution.
Healthy depth and generally stable tradability.
Tradable but less resilient during volatility spikes.
Wider spreads and higher slippage risk.
Sparse market depth and fragile execution quality.
Neutral fallback style aligned with Hold.
Price bands: four markets, four books
What works on a $5 promo and what works on a $500 chase card are different games, so the playbook treats them as different games.
Every card sits in a price band (set by its 30-day median price), every pattern is tested and graded separately inside each band, and every call keeps the band it was made in forever, so no band's record can ever borrow another's.
75% of qualified buy entries higher 8 weeks on · median +17%
80% of qualified buy entries higher 8 weeks on · median +25%
82% of qualified buy entries higher 8 weeks on · median +32%
84% of qualified buy entries higher 8 weeks on · median +21%
Those figures come from the held-out validation slice of our backtest, data the rules never saw while they were being tuned. The cheaper the card, the stricter the rules: chasing a fresh spike burned worst at the bottom of the market, so that is where the caps bite hardest.
