Bank Nifty Trading Journal: Units, Expiry and Review

A Bank Nifty trading journal should keep the actual contract, expiry, direction, actual executed prices, lots and total units beside the setup and exit reason. Do not build a current log around weekly Bank Nifty options: NSE discontinued those contracts. Use the precise expiry in your execution record, and calculate options from premium changes or futures from futures-price changes. This prevents an index move from being mistaken for your trade result.

A contract reference with dates

NSE's lot file, checked 15 Oct 2026, shows 30 units per Bank Nifty lot for the October, November and December 2026 series. This is a units-per-lot figure, not the number of lots you traded. Keep historical entries at their actual executed quantity.

NSE/FAOP/64506, dated 10 October 2024, names 13 November 2024 as the last Bank Nifty weekly option expiry. Current monthly and longer-dated options should not be labelled weekly. NSE's current specification lists expiry on the last Tuesday of the expiry period, adjusted to the previous trading day if it is a holiday.

The Tuesday transition is documented in NSE/FAOP/68747, dated 25 June 2025, for September 2025 onwards contracts, with specific provisions for long-dated realignment. Use an actual contract date when comparing expiry trades; a calendar weekday alone does not identify the position.

Bank Nifty and Nifty Units Side by Side

Bank Nifty and Nifty are different contracts with different units. NSE's lot file, as held in this site's lot reference and checked on 28 Oct 2026, shows 30 units for Bank Nifty and 65 units for Nifty. A one-point move in the Bank Nifty future is worth 30 × ₹1 = ₹30 per lot, against 65 × ₹1 = ₹65 for Nifty. Index levels differ too, so compare rupee risk, not points.

Worked futures loss: keep points and rupees distinct

Made-up example: buy a Bank Nifty futures lot at 54,000 and sell at 53,940 before expiry. With the cited 30-unit lot, the gross loss is (54,000 - 53,940) × 30 = ₹1,800. Using the charge estimate in the next section, costs come to about ₹962.45, so the net loss is ₹1,800 + ₹962.45 = ₹2,762.45. The price levels are fictional, and this uses futures fills rather than option premiums.

If the entry matched your setup and the exit followed the original stop, record that even though the result is negative. If you changed size after an earlier loss, write the reason. A losing outcome alone cannot tell you whether a rule was broken.

The Same Futures Trade With a Full Charge Estimate

Futures charges are larger than many beginners expect, because STT is charged on the full contract value. Zerodha's charges page, opened on 28 Oct 2026, shows brokerage of 0.03% or ₹20 per executed order, whichever is lower, STT of 0.05% on the sell side, an NSE futures fee of 0.00183%, stamp duty of 0.002% on the buy side, SEBI fees of ₹10 per crore and GST of 18%. Other brokers differ, so your contract note decides.

Gross loss was ₹1,800, so the loss after charges is ₹1,800 + ₹962.45 = ₹2,762.45. A fictional 60-point move produced charges worth about half the price loss, which is why futures traders must record charges on every trade.

Bank Nifty decision notes worth keeping

• Exact setup and condition that would cancel it, recorded before knowing the outcome.
• Any event you considered, with when you learned about it and how it changed the plan.
• Planned quantity and actual quantity, including added or reduced lots.
• Entry emotion and whether the decision followed a previous gain or loss.
• The exit condition, actual action and any deviation from your written rule.

These are suggested observations, not a promise of automatic policy-event or strike-distance analysis. Use the options journal to preserve strikes and legs, and a psychology note for impulse decisions.

Recording Event Days and Expiry Week

Bank Nifty is made of bank shares, so results from banks, policy announcements and credit data can move it. You do not need to predict these. You need to record what you knew, when you knew it, and whether the plan changed.

• Event name and the time it was scheduled, as shown in an official calendar.
• Whether you traded before the event, during it or after it.
• Whether your size was the same as on a normal day.
• The expiry date of the contract and the days left when you entered.
• What you did in the last days before expiry: held, rolled or closed.

Because Bank Nifty has monthly expiry only, the last week of the month is a natural group to review on its own. Compare it with the other weeks using the same strategy and size.

Futures or Options: Keep Two Separate Logs

Mixing the two in one average hides the differences. See futures vs options, how to trade Bank Nifty options and understanding the Bank Nifty.

Compare records before changing your routine

Compare the same instrument type and setup, with position size and costs visible. Keep futures apart from options, and planned trades apart from entries you marked as deviations. The Nifty journal uses different contract units, so compare cash results and decision quality rather than assuming equal lots mean equal exposure.

OneTradeJournal provides manual entries, emotion and mistake recording, strategy and time analysis, and charge estimates. Its pre-trade checklist warns but cannot block an order. Use the review guide to investigate a pattern; no journal can certify a future Bank Nifty edge.

Common Bank Nifty Journal Mistakes

• Using Nifty's unit count for a Bank Nifty trade, or the reverse.
• Entering a weekly label for a current Bank Nifty option.
• Writing profit in index points when you traded an option premium.
• Leaving out STT, which is large on futures.
• Recording an assumed fill, not the filled price.
• Changing size after a loss without writing down why.

If you also trade Nifty, keep them in separate groups. The Nifty vs Bank Nifty guide explains how the two differ.
