Win Rate: Why 70% Wins Can Still Bankrupt You

Feature Spotlights August 4, 2026 6 min read By Coinlio Team

A 70% win rate sounds great — until you do the math

Win rate is the most-quoted number in trading and the most misleading. "I win 7 out of 10 trades" sounds like a flex. But if your wins are tiny and your losses are huge, you can win 70% of the time and still go broke.

This is the trap that catches more retail traders than any other. They fixate on win rate, design strategies to maximize it (cutting winners early, holding losers long), and end the year wondering why their account shrank despite "winning most of the time."

💡 Tip

Win Rate appears on Coinlio's Insights tab in the Trading Stats section. It is calculated automatically — but the number only matters when you read it next to R-Multiple.

What is Win Rate? (definition + formula)

Win rate is the simplest trading metric on the planet. It tells you what fraction of your closed trades ended in profit.

📝 Note

Win Rate = Winning trades ÷ Total closed trades × 100%
A winning trade = any closed round-trip with positive net P/L (after fees). A losing trade = anything else.

The formula could not be simpler. The interpretation is where everything goes sideways. A win rate of 40% can be wildly profitable, and a win rate of 70% can be a slow bleed — depending on the size of your average winner versus your average loser.

Worked example: 30 trades, 40% win rate, profitable strategy

Imagine a trend-following trader took 30 trades over 3 months. Twelve closed in profit, eighteen in loss. Win rate = 12 / 30 × 100 = 40%.

Sounds bad, right? Now look at the size of the trades. Average winner: +$250. Average loser: -$100. R-Multiple = 250 / 100 = 2.5.

Math the result. Total profit = 12 × $250 = $3,000. Total loss = 18 × $100 = $1,800. Net = +$1,200. The trader "loses" 60% of the time and is up 12% of a $10k account.

A 40% win rate paired with a 2.5 R-Multiple beats a 70% win rate with a 0.4 R-Multiple every time. Win rate alone tells you nothing about whether you are profitable.

Now flip it. Same trader, but they cut every winner at +$50 "to lock in the win" and hold every loser to -$300 "because it will come back." Win rate jumps to 70% (21 wins, 9 losses). Total profit = 21 × $50 = $1,050. Total loss = 9 × $300 = $2,700. Net = -$1,650. They feel like they are crushing it. They are losing money.

The Win Rate threshold scale (depends on your style)

Unlike Profit Factor, win rate does not have a single "good" number. The right range depends entirely on your trading style and your R-Multiple.

35% – 50% — Trend-following territory. You catch occasional big moves and accept frequent small losses. Pairs with R-Multiple of 2.0+.
50% – 65% — Mean-reversion / swing trading. Most discretionary retail traders sit here. Pairs with R-Multiple of 1.0–1.5.
Above 70% — Suspicious on small samples. Either you have an exceptional system, you are cherry-picking trades, or your R-Multiple is below 1.0 (winners smaller than losers — a hidden trap).
Below 35% — High risk-reward strategies. Possible for breakout traders chasing 5R+ moves. Most people who land here are not doing it on purpose — they are just bad.

⚠️ Warning

If your win rate is above 70% AND your R-Multiple is below 1.0, you are in the danger zone. You feel like a winner because most trades close green, but you are slowly bleeding capital. Coinlio flags this combination on the Insights tab.

3 common mistakes that make Win Rate misleading

Almost everyone reads win rate wrong the first time. Here are the three patterns that cause the most damage.

Looking at Win Rate without R-Multiple

This is mistake #1. Win rate without average winner ÷ average loser is incomplete information. Always read them together. A 50% win rate with R=2 is profitable. A 50% win rate with R=0.5 is a loss. Same win rate, opposite outcomes.

Optimizing for Win Rate instead of profit

Many traders try to "raise their win rate" by closing winners early and holding losers "until they recover." This guarantees a high win rate AND a shrinking account. Stop chasing the number. Chase the math.

Judging Win Rate on tiny samples

A 7-trade sample with 5 wins is 71% — but it is also statistical noise. You need at least 30 closed trades before win rate stabilizes. With 100+ trades, the number gets reliable. Below 30, treat it as a hint, not a verdict.

Win rate measures how often you are right. Profit measures how much you make when you are right. Only one of those pays the bills.

How Coinlio computes Win Rate for you

Coinlio calculates Win Rate automatically on the Insights tab, in the Trading Stats section. The number lives in the StatCardView Win Rate cell, right next to R-Multiple — so you always see them together.

The calculation uses every closed round-trip trade in your portfolio (a round-trip = one buy followed by one or more sells of the same asset that close out the position). Fees are included in the win/loss determination, so a trade that profited $5 in price but cost $7 in fees counts as a loss — as it should.

Win Rate cell — your % of winning trades, updated in real time as new trades close.
Paired with R-Multiple — the next cell shows your average winner ÷ average loser. Read them together, never alone.
Sample size note — Coinlio shows a small note when you have fewer than 30 closed trades, so you do not over-interpret early data.

💡 Tip

To find it: open Coinlio → tap Insights tab → look at the Trading Stats grid. Win Rate is the second cell, right after total trades.

What to do once you know your Win Rate

Win Rate is one piece of a three-metric puzzle. Use it like this:

High Win Rate (>70%) but low R-Multiple? You are cutting winners early. Let them run longer. See R-Multiple: Are You Cutting Winners Too Early?
Low Win Rate (<40%) and low R-Multiple? Strategy is broken on both axes. Stop trading until you can identify why your entries fail. See Profit Factor.
Win Rate looks good, R-Multiple looks good, but Expectancy negative? Fees are eating your edge. See Expectancy per Trade: How Much Do You Make on Average?

Win Rate, R-Multiple, and Expectancy together tell the complete story. None of them works alone. The best traders look at all three before adjusting their strategy — most retail traders look only at win rate, which is exactly why most retail traders lose.

Win Rate alone is meaningless. A 40% win rate with R=2.5 prints money. A 70% win rate with R=0.4 quietly drains your account. Always read win rate paired with R-Multiple.
