Journaling and review · Lesson 1 of 23 min read

Keeping a trading journal, and reviewing it

A research call has its own record. Your trades need one too: the calls you took, how you entered, sized and exited, and why. Without it, it is hard to tell whether a loss came from the research, from your execution or from your size.

1. What to record for each trade

  • The call: instrument, direction, entry zone, stop-loss, targets, timeframe, and when you saw it.
  • Your entry: time, your fill and your quantity or lots, and how you worked out the quantity.
  • Your risk: rupees to the stop at entry. This is 1R for the trade.
  • Your exit: time, price and reason: stop-loss, target, trailed stop, the analyst's instruction or your own decision.
  • Costs: brokerage, taxes and charges, from the contract note.
  • Anything you did differently from the plan: a late entry, a moved stop, a larger size, an early exit.

2. Measure in R

Result in R = (exit − entry) ÷ (entry − stop-loss) for a BUY, using your own fill and the stop at entry. R makes a ₹500 result on a small trade and a ₹5,000 result on a large one comparable.

Three made-up trades in rupees and in R
TradeIn rupeesIn R
100 shares bought at 500, stop 490, exit 515+₹1,500+1.5R
20 shares bought at 2,000, stop 1,950, exit 1,950−₹1,000−1.0R
1 lot of 65 bought at 1,200, stop 1,180, exit 1,190−₹650−0.5R

3. A weekly review

  1. Total the week in R and in rupees, after costs.
  2. Mark each trade as following your plan or departing from it, and total each group.
  3. Compare each trade with its call: your fill with the call's fill, your exit with the call's exit.
  4. Look for repeats. The same mistake twice in a week is a rule to write down.
  5. Choose one change for next week, and only one.

4. A wrong call, or a problem with execution?

Reading a loss in your journal
What happenedWhat it points to
The call reached its stop-loss, and you exited thereThe view was wrong this time. A normal, planned loss.
The call reached a target, but you closed at a lossExecution: a late entry, a tighter stop of your own, or an early exit.
Your loss was much larger than 1RSize or stop discipline: a moved stop, a gap, or an oversized trade.
You took calls outside the segments you planned to followSelection: trades outside your plan.

5. Where to keep it

A spreadsheet works, and so does a notebook or a journaling app. Whatever you use, record your own fill price and quantity from your contract note, not the levels you planned.
