Importing from any broker with column mapping

Map an unsupported broker's CSV columns to trade fields once.

Not on the supported list? The column mapper imports a CSV from any broker or platform. When you drop a CSV that isn't a recognized broker format, the mapper opens automatically.

Mapping your columns

  • We auto-guess the mapping from your header names — you just confirm or adjust.
  • Point each trade field (symbol, side, quantity, price, date, fees…) at the matching CSV column.
  • Configure which token means “long” and toggle day-first dates if your export uses DD/MM.
  • A live preview flags any rows with problems before import.

What gets imported

Only valid rows are imported, through the same validated, de-duplicated pipeline as native imports. In the column mapper, one row = one trade (bespoke broker importers are the ones that pair fills into legs).

Building the file yourself, or want the mapping to fill in automatically? Use the CSV import template.
