THE DIAGNOSIS
- ~89% of Indian F&O traders lose money (SEBI). The root cause isn't picks — it's no feedback loop.
- No journal → no feedback → no improvement → only repetition.
THE INSTRUMENT (not a diary — a measurement tool)
- Broker statement = what you traded. Journal = why, how, and whether you followed your plan.
- The lessons live in the gap between them.
PLAN (before the trade — this is the first journal entry)
- Entry · Stop · Target · Size (as % of capital) · Reason · Emotion — written BEFORE you click.
- Strategy = a numbered checklist, not a vibe. Grade rules-met per trade.
- Check the trade against your account (risk/trade, daily loss limit, max drawdown), not just the chart.
CAPTURE (make it cheaper to feed than to skip)
- Import from broker; don't re-type. Auto-tag option legs. Track MTF interest per day.
- Log the stop you MOVED (timestamped) — that's who you are, not just what you did.
- Track NET P&L, not gross. Indian costs (STT/GST/stamp/brokerage) and MTF hide the truth.
REVIEW (where all the compounding happens)
- Grade behaviour, not outcome: plan-adherent loss = good trade; plan-breaking win = dangerous.
- MAE/MFE: was it process or luck? A deep-underwater winner is a rescued mistake.
- Metrics that matter: EXPECTANCY, R-MULTIPLE, PROFIT FACTOR — not win rate alone.
- Slice by setup/regime/weekday/symbol — averages hide the assassin.
THE LOOP (calendar it)
- Daily (10 min): discipline check. Weekly (30): pattern scan. Monthly (1 hr): metrics. Quarterly (½ day): strategy audit.
- Write every lesson back as a rule. A lesson kept only in your head is scheduled for re-purchase.
THE ONE NUMBER
- Do your PLANNED trades beat your UNPLANNED ones? Compute it once. It decides everything.
TAX
- Same record = your ITR file. F&O = business income. Keep dates, segments, net P&L, itemized charges. (Confirm with a CA.)
