Portfolio Performance
Retrieve cash-flow-adjusted daily P&L, time-weighted returns, and optional benchmark comparisons for master and customer portfolios.
Use GET /portfolio/performance for the partner master account and
GET /users/{userId}/portfolio/performance for a customer sub-account. These endpoints are distinct
from /portfolio/history, which intentionally returns raw equity snapshots without cash-flow adjustment.
| Field | Type | Required | Description |
|---|---|---|---|
| period | string | No | 1M | 3M | 6M | 1Y | ALL. Defaults to 1Y. |
| from | date | No | Optional inclusive ISO date override. |
| to | date | No | Optional inclusive ISO date override. |
| benchmark | string | No | Exchange-qualified symbol used for a rebased price-return comparison. |
Each point includes equity, marketValue, netCashFlow, dailyPnl, dailyReturn,
cumulativeReturn, and—when requested—benchmarkReturn plus excessReturn.
Methodology
- Daily P&L is
end equity - start equity - net external cash flow. - Each interval uses Modified Dietz, weighting completed cash flows by the time remaining in the interval.
- Daily returns are geometrically linked to produce cumulative time-weighted return.
- Sub-account
DEPOSITandWITHDRAWALentries are external cash flows. - Master-account internal transfers and completed top-ups/payouts are adjusted so funding movement is not reported as investment return.
- Benchmark comparison is price return rebased to the first available close. It excludes dividends and FX and must be labelled accordingly.
Performance is only as complete as the available daily valuation snapshots. Do not fabricate intraday returns from delayed quotes, and do not present the benchmark comparison as total return.
