How this service works
Trading journal observations — Daily sum series + Explicit missing-value fill: Daily sum series + Explicit missing-value fill 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: a daily sum time series aggregating the selected price field (entry_price or exit_price) across rows by date, and an explicit missing-value filled version of that series using the chosen fill method (zero, mean, or median). Covers up to 200 input rows organized by instrument group and date.
Example use cases
Daily PnL aggregation by instrument
“I have my trading journal records for October with entry and exit prices for two instrument groups — can you compute the daily sum series for exit_price and fill any missing values using the median so I can see my daily totals per group?”
Missing entry price imputation for backtesting
“Some of my backtesting trade records are missing entry_price values — can you run a daily sum series on these 50 rows and fill the blanks with zeros so my backtest engine doesn't break?”
Trade data quality check before reporting
“Before I submit my monthly trading report, can you aggregate my journal entries by date and fill any missing entry_price gaps using the mean — I have about 120 rows with instrument groups and I need two summary reports?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-finance-09-145?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have structured trading journal records with entry and exit prices, need a daily sum time series, and want explicit missing-value imputation (zero, mean, or median) — all in a single $0.01 call returning two bundled reports. Best suited for offline batch analysis of up to 200 rows; not for live market data, predictions, or real-time monitoring.
Side effects
- Missing required fields (row_id, date, instrument_group, entry_price, exit_price) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- More than 200 rows submitted causes a request rejection
- Invalid enum values for 'field' or 'method' parameters cause errors
- All-null price columns may produce degenerate fill results
- Payment failure or insufficient USDC balance blocks the call
