How this service works
Trading journal observations — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + Equal-width histogram 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 reports: (1) a grouped numeric summary of the chosen price field (entry_price or exit_price) broken down by instrument_group, including statistics like mean, min, max, and count; and (2) an equal-width histogram showing the frequency distribution of the selected price field across the specified number of bins. All analysis is performed locally on the supplied data with no external lookups.
Example use cases
Trade entry price distribution review
“I have 120 rows from my trading journal — each with a row_id, instrument_group, date, entry_price, and exit_price. Can you give me a grouped numeric summary and a 10-bin equal-width histogram for the entry_price field so I can see how my entry prices are distributed?”
Exit price analysis by asset class
“Here are 80 trade records grouped by instrument class — I want to analyze exit_price. Run a grouped numeric summary and a 5-bin histogram on the exit_price column so I can spot patterns across groups.”
Pre-review stat report for portfolio journal
“Before my quarterly review I need statistics on my last 200 trades. Can you compute a grouped numeric summary and equal-width histogram with 15 bins for entry_price across all my instrument groups using this trade data?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-finance-09-093?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have trading journal data with entry and exit prices already in hand and need both a grouped statistical summary and a histogram in one call for up to 200 rows. It is ideal for offline batch analysis of trade records without requiring live market data, predictions, or external lookups. Prefer it over generic statistics APIs when you specifically need instrument_group-level breakdowns paired with histogram binning in a single low-cost ($0.01) request.
