What is the Lurk Score? The Lurk Score is a dynamic, single-number metric (0–99) designed to measure a trader’s true efficiency. Unlike other platforms that rank purely by PnL (which favors the rich) or Win Rate (which can be statistically insignificant), the Lurk Score balances Skill, Risk, and Scale. It answers one question: How hard is it to replicate this performance?

The Formula We believe in transparency. Here is exactly how we calculate your rank.

Note: If your Profit Factor is below 1.0 (unprofitable), your score is capped at 49. You cannot "buy" a high rank with volume if you are losing money.

**The Components

  1. Profit Factor (The Skill Base)** • Why: Win Rate is a vanity metric. You can have a 90% Win Rate picking up pennies and lose it all in one bad trade. • How it works: We measure Gross Wins / Gross Losses. ◦ < 1.0: Losing Trader. ◦ 1.5: Solid Professional. ◦ 3.0+: Elite. • Impact: A Profit Factor of 2.0 grants you 100 base points (before risk penalties).

2. Drawdown (The Risk Penalty) • Why: Returns are meaningless if you risk blowing up the account to get them. • How it works: We subtract half a point for every 1% of Max Drawdown. ◦ 10% Drawdown: -5 Points. ◦ 40% Drawdown: -20 Points. • Impact: Volatile strategies can work, but you must generate massive returns to justify the risk.

3. Logarithmic Volume (The Purity Bonus) • Why: It is exponentially harder to trade with $10,000,000 than it is with $10,000. Slippage, liquidity, and psychology change the game. • How it works: We apply a logarithmic scale to your total volume. ◦ $10k Volume: +6 Points ◦ $1M Volume: +9 Points ◦ $100M Volume: +12 Points • Impact: Volume acts as a "tiebreaker." If two traders have identical stats, the one moving more money ranks higher.

Quick FAQs

  1. Why is my score low despite a 90% Win Rate? You likely have a poor Profit Factor (your wins are small, your losses are big) or you have very low Volume. A 90% win rate on $500 volume is statistically insignificant.

  2. Can I game the system by spamming volume? No. If your spam trades result in losses, your Profit Factor drops below 1.0, and your score is instantly capped at 49. Volume only helps winners.

  3. How often does the score update? Scores are recalculated in real-time as trades close.
