A Drawdown and a Dead Strategy Look Identical From Inside

Down 18% from your peak. Six weeks and counting. Every trade the system takes seems to lose, and the ones it skips would have won.

Here's the question that decides everything: is this a drawdown, or is your strategy dead?

From the inside, they're identical. Same red equity curve, same knot in your stomach, same voice telling you to pull the plug. That's the whole problem. The feeling gives you zero information about which one you're actually in.

A drawdown is temporary by definition. It's the gap between your account's highest point and wherever it sits now, and a working strategy climbs back out of it eventually. A dead strategy produces the same red curve — except it never recovers. The market changed, your edge evaporated, and the losses just keep stacking.

The math on drawdown duration is more brutal than most people expect. For a trend-following system with a Sharpe ratio of 0.7 — which is genuinely good — a typical drawdown lasts about two years. Drawdowns of four years aren't exceptional. Read that again. A profitable, well-built strategy can spend two to four years underwater and still be perfectly healthy.

Most traders have no idea their system is supposed to hurt this long. They expect a rough month, maybe a bad quarter. When the pain runs past that, they assume it's broken.

The mistake is judging the strategy by how the drawdown feels instead of by what it does. And there's no felt difference between month three of a normal drawdown and month three of a permanent one.

So people invent a signal that doesn't exist. "It just feels different this time." "The market's structurally changed." Maybe. But you're pattern-matching on emotion, and emotion peaks at exactly the wrong moment — near the bottom, right before the recovery.

In 2022, BTC fell 77%. Plenty of solid strategies got dragged into deep drawdowns that year. The ones that survived weren't the ones with better systems. They were the ones who knew their system's limits and didn't flinch.

The only real way to tell the two apart is to know your numbers before you're in the hole. What was the worst drawdown in your backtest? How long did it last? How many losing trades in a row did it string together? If your live drawdown is still inside those historical bounds, you're not broken. You're just uncomfortable.

If you never measured that, you're flying blind. You'll quit a fine strategy at the bottom and chase a new one right into its own drawdown.

So write down three numbers for whatever you trade: max historical drawdown depth, max drawdown duration, and longest losing streak. Tape them somewhere you'll see them. When you're down and the doubt creeps in, check the live numbers against those three.

A strategy is dead when it breaks its own historical bounds — a drawdown deeper or longer than anything in its tested history, or a change in the market you can actually name and point to. Not when it hurts. Hurting is the price of admission.

This is the hardest call in trading to make by feel, which is exactly why we automate it. A system doesn't panic in month three. It doesn't confuse a normal drawdown for a dead one, because it isn't afraid.
