Statement and export parsers for Trade Journal, LuxAlgo's open-source trade journal. Zero runtime dependencies beyond @luxalgo/journal-core. Runs in Node and the browser.

npm install @luxalgo/journal-importers

What it does

Turns broker and journal exports into normalized executions, ready for buildRoundTrips.

import { parseAuto, parseWithMapping, readHeaders, FORMATS } from "@luxalgo/journal-importers";

const parsed = parseAuto(fileText, { timeZone: "America/New_York" });
// -> { format, executions, warnings, skippedRows } or null when unrecognized

Auto-detects 12 formats: TradeZella and Tradervue (one-click migration), TradingView, MetaTrader 4 statements, ThinkorSwim / Schwab, Interactive Brokers (activity CSV + Flex Query), NinjaTrader, Tradovate, TopstepX, Webull, DAS Trader.
parseWithMapping handles any other CSV through a user-defined column mapping; nothing is guessed silently.
Handles quoted fields, BOM, ; and tab delimiters, $1,234.56 and (45.20) numbers, European decimals, timezone suffixes, and DST-safe naive-timestamp conversion.
TradeZella imports reconcile stated net P&L to the cent, so migrated history matches the trader's old numbers.

Per-format validation status lives in docs/importers.md. Real export samples are the most valuable contribution. MIT.
