Drawdowns & Losing Streaks: What’s Statistically Normal
A drawdown is the drop from a peak in your account to a later trough, measured before a new peak is made. A losing streak is a run of consecutive losing trades. Both are not signs of a broken system — they are the unavoidable texture of any strategy whose edge plays out over hundreds of trades. Even a system that wins most of its trades will, with mathematical certainty, produce uncomfortable strings of losses. The job is to know what is normal so you do not abandon a sound process at exactly the wrong moment.
What a drawdown actually is
Drawdown is peak-to-trough decline, usually expressed as a percentage of the account. If a simulated $100,000 account rises to $112,000 and then dips to $106,000 before recovering, that is roughly a 5.4% drawdown from the peak. It is a measure of pain, not of failure: every strategy that takes risk has them. What separates a healthy system from a broken one is whether drawdowns stay inside the range its win rate and risk-per-trade predict.
Why even a winning system has losing streaks
Take a system that wins about 58% of its trades — a genuinely strong rate. That means it loses roughly 42% of the time. Treating trades as independent draws, the chance of several losses in a row is just that loss probability multiplied by itself: two straight is about 18%, three straight about 7%, four straight about 3%. Over a long record those low-probability runs are not rare — they are required. Jack Schwager’s Market Wizards interviews return to this repeatedly: the traders who survive size their positions so an ordinary streak cannot end them, and they do not tear up a system because a normal bad run feels abnormal in the moment.
The expected longest losing streak
Across any rolling 100-trade window, a system that wins around 58% of its trades has an expected longest losing streak of roughly four to six trades, with the occasional run stretching a little further by pure variance. So a three- or four-trade losing week is not the deep tail of the distribution — it is the body of it, showing up at week resolution. Van Tharp’s R-multiple framework makes the same point from the expectancy side: see understanding R-multiples for why a cluster of −1R results barely moves a positive-expectancy ledger.
What a normal drawdown depth looks like
At fixed-fractional risk — say 2% of the account per trade — a positive-expectancy system will routinely produce single-window drawdowns in the 5–10% range over the course of a year, and deeper ones occasionally. The depth scales with risk per trade: double the risk and you roughly double the drawdown. This is why disciplined sizing matters more than any single setup. A bounded, known give-back on a bad week is the cost of admission for the compounding on the good ones.
When a drawdown is a signal, not noise
A drawdown becomes worth investigating only when it exceeds the historical range the system has shown across hundreds of trades — think of the 95th percentile of past equity dips. Inside that band, a drawdown is noise. Beyond it, sustained for a meaningful sample, it may indicate the edge has degraded or the market regime has shifted. The number to watch is never a single bad week; it is a drift in win rate or average R across a large sample. One uncomfortable stretch is data, not a verdict.
How SkyAnalyst publishes its drawdowns
Most platforms show only winners. SkyAnalyst publishes a weekly losses report every week the desk takes a loss — the same arithmetic any legitimate fund discloses. Each report pairs the week’s losing trades with the statistical context above and ties them back to the year-to-date record so a red week reads as variance, not catastrophe. You can see the win side in the weekly recap, and the full accounting of how we score it in how we measure trading performance.
Drawdowns & losing streaks FAQ
Is a 10% drawdown bad?
Not necessarily. For a system risking around 2% per trade, single drawdowns of 5–10% are routine across a year. What matters is whether the drawdown stays inside the range the system’s win rate and risk level predict, and whether the equity curve makes new highs over a large sample.
How long do losing streaks usually last?
For a system winning ~58% of trades, the expected longest losing streak over 100 trades is about four to six, with rarer longer runs. A three- or four-loss week is well inside normal variance, not evidence of a broken system.
Does a losing streak mean the system stopped working?
Almost never on a small sample. A handful of consecutive losses is statistically expected. Degradation shows up as a sustained drift in win rate or average R across hundreds of trades — not as one bad week.
Why would a platform publish its losses at all?
Because every legitimate fund discloses drawdowns, and a record that only shows winners is marketing, not evidence. Publishing losses with their statistical context is how you prove an edge is real rather than cherry-picked.

This article is educational and explains trading concepts and how the SkyAnalyst system measures itself. It is not financial advice, and nothing here is a promise of future results. Trading involves risk of loss. Performance figures cited are simulated on a $100,000 account at 2% risk per trade unless stated otherwise, and past performance — including drawdowns — does not guarantee future outcomes.
