Trading accounts and starting capital
2 min readUpdated
Set your account size correctly, record deposits and withdrawals, and understand which metrics depend on them.
Every trade belongs to a trading account, and every account has a starting capital figure. That figure is the denominator behind ROI, risk percentages, and capital-relative reporting — so it is worth getting right before you read too much into any of them.
Creating and switching accounts
Accounts live in Settings → Account. A new signup gets one automatically, so you can start immediately. Use separate accounts when the capital is genuinely separate — a funded account and a personal one, say — not merely to group strategies, which strategy tags already do.
The sidebar account switcher decides which account you are looking at. Trades, the capital ledger, and every metric are scoped to the active account; the notification feed and your import history are not, since a notice about another account is still worth seeing.
Deposits and withdrawals
Money moving in or out is not a trading result, so it is recorded separately in the capital adjustment ledger rather than being folded into P&L. Your current capital is the starting figure netted against every adjustment, floored at zero.
Amounts are always entered as positive numbers — whether it adds or subtracts is decided by choosing deposit or withdrawal, not by the sign.
Why drawdown ignores your current balance
Almost every capital-relative figure uses your current capital. Maximum drawdown deliberately does not, and the reason is worth understanding: a single current snapshot has no notion of when money moved.
If drawdown were measured against today's balance, a large withdrawal would shrink the denominator across your account's entire history and spike a drawdown no trade ever caused — while a later deposit would shrink drawdowns that happened before those funds existed. Instead, the equity walk merges your dated adjustments in chronological order, so each point is measured against the capital actually in place at that time. A transfer is never itself a loss, and never a recovery.
