Trade Sample Window
The Trade Sample Window controls which position opens are included in the current sample. Common product options include:
API stats reads use explicit
startTime and endTime bounds for the same idea.
Time-Based Performance Window
The Time-Based Performance Window controls when return is measured after entry.
Example: sample =
30d, performance window = 7D means “positions opened in the sample, measured seven days after each open.”
Core metrics
Metrics can be null when there are no accessible rows, not enough evaluated positions, or no usable fixed-window return for the requested window.
Open-position return
Open-position return is different from time-based performance. It uses the current mark price when available: Long:(current price - entry price) / entry price
Short: (entry price - current price) / entry price
Open-position reads are the right source for current exposure and open-position skew. They do not prove how the trader will close the position.
What not to do
- Do not treat generated narrative summaries as evidence for exact performance.
- Do not compute win rate by manually scanning event rows.
- Do not mix current open-position return with
1D,7D, or30Dtime-based performance. - Do not assume a missing metric means zero performance; it usually means unavailable or inaccessible data.
