A good win rate is not an edge.

The journal for crypto perps on Bybit and Hyperliquid. Connected read-only, it fills itself, and then shows you what actually decides the result: payoff, costs, the rules you broke yourself.

PerpLog dashboard for the demo account: 120 trades, a 53.3% win rate, yet −$521.94 net P&L and a 0.95 profit factor: an unprofitable account, because win rate alone doesn't tell you whether you're making money.
The dashboard after the first sync: net of funding and fees, not the exchange's gross number.

From the demo account · one setup, 15 trades

One setup wins 66.7% of its trades. By P&L it ranks second worst.

That setup sits inside an account that wins 53.3% of its 120 trades and still closes at −$521.94. The winners bring in $9,916.86 between them; the losers cost $10,438.80. More hits, less money.

PerpLog breaks that result down trade by trade. Every percentage carries its denominator, and no row disappears because it doesn't fit the picture.

The finding
The 66.7% come from 15 trades, and they cost $239.06 on balance. At that sample size it is a pattern, not proof. PerpLog shows you the count and the spread instead of passing judgement on fifteen trades.

A rule you never wrote down is a rule you can't check.

51.5% of the logged trades followed the plan in full. Trades often break more than one rule; the entries overlap.
Define the rules once. PerpLog checks every closed trade against them: stop set? risk within limit? setup actually met?

Risk & liquidation proximity

Pro

Distance to liquidationvisible before you enter

Sizing stays silent below 20 closed trades and on an unproven edge — no Kelly math on noise.

Works off your real numbers: a capped Half-Kelly as the suggestion, and next to it the odds of losing half the account at that size.

After the trade

Trade replay with annotations

Pro
Trade replay in the demo account: an ETHUSDT short entered at 1,880.15 and exited at 1,898.00 for −$119.08, with the stop-loss line at 1,900.68, the target at 1,812.34, and the P&L curve showing how far into profit the trade had been.
You see the trade the way it ran: the entry, how far it went for you, and the candle where you broke your own rule.

Observed gap between the two groups — an association, not a causal estimate.

PerpLog prices the gap between your calm and your tilted trading: per trade, so the figure cannot grow with your good trades. It never appears without the count it came from.

Dashboard coaching
One trade is a data point, not a rule — PerpLog counts how often you let winners round-trip.

Reads your recent trades and names the pattern (revenge, tilt, overtrading), always with the trades it came from.

Over time

What PerpLog can do, and what it can't.

You are connecting a trading account. Here is what happens with it, and what does not.

PerpLog reads

  • Closed trades & executions
  • Funding payments & fees
  • Open positions & wallet balance

PerpLog cannot

  • Place or change orders
  • Withdraw or transfer
  • Ask for a key on Hyperliquid at all (a wallet address is enough there)

Your data

  • Keys encrypted with AES-256-GCM, master key not in the database
  • CSV export on the Free plan, no lock-in
  • Account and data deletable at any time

What the AI coach sends is named in the privacy policy — Anthropic does not train on it.

Staying honest: a read-only key still exposes your trading and account data. That is why I store it encrypted, and why you can revoke it at any time.

Who builds this

Julien

I build PerpLog on my own and trade perps on Bybit myself. No VC, no investor roadmap. Features ship in the order active traders need them, and support comes straight from me.

I built PerpLog after my own account showed me that a good win rate was hiding a negative payoff. I journal my trades here — the account is down, and the journal shows exactly why.

PerpLog is new. There are no customer quotes I could honestly show you. That is why the whole demo account is open, with no signup.

And if PerpLog ever shuts down: 30 days notice by email, with a final export link. Your history leaves with you.

Common questions

Security and data access are answered above. Here is the rest.

Bybit (USDT perpetuals, read-only API key) and Hyperliquid (perps, read-only wallet address, no keys at all), including Hyperliquid's builder-deployed markets. Binance, OKX and Bitget aren't in yet; more exchanges are in the works, but quality comes first: every integration has to get funding, fees and partial fills right. Tell me which exchange you're missing.

TradeZella and Tradervue are multi-asset tools: stocks, options, futures, crypto in one. PerpLog does one thing: crypto perpetuals on Bybit and Hyperliquid. Two concrete consequences: funding payments are properly aggregated to the trade instead of disappearing as "misc fees", and if you set rules on a strategy (SL required? Risk within limit?), the Setup Compliance Engine automatically checks every closed trade against them. If you trade crypto perps, you want crypto-specific.

If you actually maintain it and extract patterns from it: yes, then you don't need PerpLog. What Excel doesn't do: aggregate funding payments to trades, compute MFE/MAE excursions, cluster trades by time-of-day or setup, or ask you at trade close whether it broke your own rules. PerpLog automates the bookkeeping so you can spend the time on pattern work, not table work.

Up to 2 years back; that's Bybit's API limit, not mine. On first sync, PerpLog pulls all executions in that window and organizes them into trades including funding, fees, and multi-entry positions. After that, sync runs incrementally. On the Free plan you see the last 30 days of it.

Yes, fully. Trade Detail has its own mobile view with tab switching (Overview, Chart, Review, Journal, Context). No native iOS/Android apps; the mobile browser is intentionally good enough so you can review on the couch on weekends.

Can you name the mistake that repeats in your last 30 trades?
