His name was Daniel. Ran a $120,000 options book, win rate above 60%, positive expected value on every strategy. What killed him wasn't his entries. He stopped tracking his net liquidating value weekly, let underwater positions distort his real equity picture, and kept sizing as if his account was healthy. It wasn't. Six months later, he blew out.
Net liquidating value — NLV — is the true number. It's not your cash balance. It's what you'd walk away with if every open position closed right now at current market prices. Cash plus long option value minus short option obligations, marked to the live market. If you're not tracking this number daily, you're flying blind over mountains at night.
The mathematics of drawdown recovery are ruthless and non-negotiable. Lose 10% of NLV and you need 11.1% to recover. Lose 25% and you need 33.3%. Lose 50% and you need 100%. The formula is straightforward: Recovery Required = (1 ÷ (1 − Drawdown%)) − 1. A $50,000 account drawing down to $37,500 needs a 33% return just to see $50,000 again. That's not pessimism — that's arithmetic.
Protecting NLV starts with fixed fractional position sizing. Risk 1% of current NLV per trade — not 1% of your starting capital, not your peak balance, your live NLV right now. On a $50,000 account, that's $500 at risk per trade. After a drawdown to $40,000, the risk per trade drops to $400 automatically. The account breathes. Position size scales with actual equity, not wishful thinking.
Reviewing NLV weekly — plotted on a simple spreadsheet — creates a visual equity curve that makes deterioration impossible to ignore. When that curve rolls over two weeks running, prudent traders reduce exposure before the drawdown compounds. The net liquidating value definition on Investopedia clarifies exactly what brokers include in this calculation, while the broader principles of position sizing on Wikipedia and the Kelly Criterion on Investopedia give the mathematical framework serious traders use to size down into drawdowns and scale up only when NLV confirms the recovery is real.
The number that matters most isn't your last winning trade — it's the number your broker would hand you if you closed everything this second. Track it like it's your pulse, because professionally, it is.
