P&L

A green day can be full of red trades

The calendar heatmap and the trade table are two cameras pointed at the same session.

Day P&L is the sum for a calendar date. Trade P&L is per closed position. They agree on the total and disagree about everything interesting.

The day that looks fine

Twelve thousand rupees green, one hero trade, three quiet disasters. The heatmap paints that square the same shade as a clean, boring, process-perfect session.

Four losers, one outsized winner, one scratch. Illustrative journal data, not a live book and not a performance claim.

Think in financial years

Most global journals default to a January start. Indian traders and their CAs think 1 April to 31 March, so a tool that only offers rolling windows will constantly disagree with the paperwork pile.

Rolling windows are for recent process. The financial year is for the record.

Do not mix mark-to-market with closed-only

If Monday includes open positions marked at the close and Tuesday counts only closed trades, your streak counter is meaningless. Pick one, label it, keep it.

Reading a day card properly
  • Net day P&L, charges included
  • Fill count against the planned activity level
  • Largest single winner and loser inside the day
  • Whether the day is closed-only or includes marked-to-market positions
  • Financial year the day belongs to, not the calendar year

Key takeaways

Your book already has these numbers. Import a broker CSV and the charts above draw themselves from your own closed trades.
