A win rate is not a profit number. On Binance Futures, every entry and exit pays a taker fee, and every open position that crosses a funding interval pays (or occasionally receives) funding. Trade often enough, and a system with a genuinely positive win rate can still bleed net-negative once fees are subtracted. This is not a hypothetical — it's arithmetic every signal seller should show you and almost none do.
The Math Nobody Shows You
Say a strategy wins 60% of trades, average winner +1.2% and average loser −1.0%, no fees. Expected value per trade:
EV = (0.60 × 1.2%) + (0.40 × −1.0%) = 0.72% − 0.40% = +0.32% per trade
Looks healthy. Now add fees. Binance Futures taker fee is typically ~0.04–0.05% per side (entry + exit = ~0.08–0.10% round trip, before any BNB discount). On a leveraged position, that fee is charged on notional, not on your margin — so at 5x leverage a 0.1% round-trip fee is 0.1% of position size, but relative to your edge measured in price-move percent, it's still a fixed tax subtracted every single trade regardless of outcome.
EV_after_fees = +0.32% − 0.10% = +0.22% per trade
Still positive here — but the moment average edge shrinks (tighter targets, choppier regime, more marginal setups let through to hit volume) or frequency climbs (more trades per day to keep signal flow up), that +0.22% margin evaporates fast. Add funding on positions held across a funding interval (often 0.01–0.03% per 8h, sometimes much higher during crowded one-sided markets) and slippage on fills during volatile windows, and a "60% win rate" system can post net-negative real money results while its raw win rate stays exactly the same.
Win Rate Is a Vanity Metric
This is the core deception in the signals industry: win rate is the easiest number to advertise and the least informative about whether you'd have made money following it. Two systems can both run 60% WR. One has fat winners and thin losers and survives fees comfortably. The other has thin winners, fat losers on the 40%, high trade frequency, and gets eaten alive by the exact same fee structure. From the outside, both look identical on a win-rate banner.
What actually matters:
- Average edge per trade after fees and funding — not before
- Trade frequency — more trades means more fee drag, not automatically more profit
- Profit factor (gross wins ÷ gross losses) — a fee-blind number is misleading here too
- Net PnL on a real account, over a real time window — the only number that can't be gamed by cherry-picking the ratio
Why We Publish the Real Net, Losses Included
Most signal channels never show this math because it's inconvenient. Ours does, because the alternative — hiding a losing stretch behind a curated win-rate screenshot — is exactly the kind of thing that gets people to size up into a system that's quietly net-negative in real conditions.
Darwin Lab runs live on a real Binance Futures account, and the full net result — every fee, every funding payment, every losing trade — is published continuously at the live track record, with the raw data available unfiltered at /api/stats.json. We're not going to tell you a number here, because the number changes and because a static figure in a blog post is exactly the kind of thing that gets stale and misleading. Go look at the live page. That's the point of publishing it live instead of writing it down.
Being candid about this is uncomfortable in an industry built on screenshot flexing. It's also the only honest way to run a signals business: the fee math above applies to every trader and every channel equally. A service that won't show you its fee-inclusive, real-account net PnL either hasn't done the math or doesn't want you to see it.
What to Demand From Any Signal Seller
Before paying for any crypto signal service, ask for:
- A live, continuously-updated net PnL on a real account — not a backtest, not a "simulation," not a curated highlight reel.
- The trade count and time window behind any win-rate claim. A 60% WR over 12 trades means nothing.
- Confirmation the number includes fees and funding. If they can't answer this cleanly, assume it doesn't.
- Losses included in whatever feed you're shown, not just wins.
If a channel can show you all four, you can actually evaluate it. If it can't, the win rate they're quoting is marketing, not information.
Check the Math Yourself
You don't have to take anyone's word for this, including ours. Watch the free Telegram channel for a few weeks, cross-reference the calls against the live track record, and do the fee math on your own account size and frequency. If you want priority delivery and more context per signal once you've verified the process, VIP is available with a free trial — no commitment required before you've seen it work for yourself.
Win rate is a headline. Net PnL after fees, on a real account, in real time — that's the only number that pays your bills.
