How this service works
Trading journal observations — Grouped numeric summary + Secondary-measure weighted mean: Grouped numeric summary + Secondary-measure weighted mean for supplied trading journal observations records (entry_price, exit_price). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.
Output
Returns two analytical reports: (1) a grouped numeric summary (e.g. count, min, max, mean, std) of the selected price field broken down by instrument_group, and (2) a secondary-measure weighted mean where the primary field values are weighted by the secondary price field, both computed locally without any external lookups.
Example use cases
Daily trade batch performance review
“I have 10 trades from last week across two instrument groups — equities and futures. Can you group them by instrument_group and give me a numeric summary plus a weighted mean of the exit_price, using entry_price as the secondary measure? Here are the rows: row-1 2024-11-01 equities entry 150 exit 155, row-2 2024-11-01 futures entry 3200 exit 3210, row-3 2024-11-02 equities entry 148 exit 152...”
Comparing entry price distributions across asset classes
“I want to see how my entry prices are distributed across my three instrument groups — crypto, forex, and commodities — for the 20 trades I logged this month. Can you give me a grouped numeric summary with the weighted mean using exit_price as the field?”
Post-session journal analytics for algo strategy
“After today's trading session I've got 50 journal observations split between strategy-A and strategy-B groups. Please compute a grouped numeric summary and secondary-measure weighted mean for exit_price on this data so I can compare how the two strategies performed.”
