What a verified track record actually means.

Every number on an SMCAlpha profile is computed by us from trade and income data pulled directly from Binance through a read-only API key. Traders cannot upload, edit, or curate their history. A profile therefore proves: these trades happened on this exchange account, this is the complete futures history we could reach, and the percentages follow from it mechanically.

• That the account is the trader's only account. Someone can run many accounts and publish the lucky one. Tenure badges (90/180/365 days of continuous verification) exist precisely because survivorship gets harder over time.
• Future performance. Nothing here predicts anything.
• History beyond the exchange's own retention: Binance serves roughly six months of futures trade fills and about 30 days of daily snapshots. Each profile shows the earliest date we could reach; nothing before it is claimed.

Our equity curve is realized: it reconstructs the futures wallet balance day by day from income records (realized PnL, fees, funding, transfers). Historical unrealized PnL of positions that were open in the past is not reconstructable from exchange data, so intraday drawdowns inside an open position are not visible. We say this plainly rather than pretend otherwise.

Every percentage derives from a time-weighted return (TWR) index: each UTC day contributes r = (E − E₀ − F) / (E₀ + max(F, 0)) where F is that day's external flow, and the index chains (1 + r) from base 100. Depositing or withdrawing money cannot move the index — a locked test in our codebase proves a large mid-period deposit produces an identical curve to a control with none.

• Max drawdown: largest peak-to-trough decline of the index.
• Sharpe / Sortino: mean daily return over (downside) population deviation, ×√365; hidden under 30 daily observations.
• Calmar: annualized TWR over max drawdown; hidden under 90 days of track.
• Round trips: positions reconstructed from fills; a reversal closes the old trip pro-rata at the flip. Trip PnL is realized PnL minus commissions; funding is reported separately as account-level drag.
• Sessions: bucketed by trip-open hour UTC — Asia 00–07, London 07–12, New York 12–21, Late 21–24; killzones London 07–10, NY 12–15.

These formulas are locked by golden tests: any change breaks our build.

Profiles default to percent-only: no dollar amounts of any kind appear publicly — not in the page, the embed, or the share card. Traders can opt into absolute values. Private profiles are simply not served.
