What each tool actually returns

A tool page is a control panel until you run something. These are the results the tools produce — the real columns, in the real layout, so you can see whether a tool answers your question before you open it.

The figures on this page are illustrative. They are shaped like a real result so the columns mean something, but no row here is a record of anything that traded. Run a tool for real data — every number it returns comes from NSE's own published end-of-day files.

Open Interest Chain

Every strike in one expiry, calls on one side and puts on the other, with what each one holds and what the session did to it.

Example output from the Open Interest Chain. Illustrative figures, not market data.
Strike	LTP	Premium chg	OI	OI chg	Volume	IV	Activity
2,400	118.40	+9.20	14,52,000	+1,86,000	2,41,300	23.4%	Long build-up
2,450	84.15	+6.05	19,08,000	+2,40,000	3,77,900	22.8%	Long build-up
2,500	56.70	-3.40	27,63,000	+4,11,000	6,02,450	22.1%	Short build-up
2,550	34.25	-2.85	21,17,000	-1,24,000	2,88,100	21.7%	Long unwinding
2,600	19.80	+1.15	16,44,000	-2,02,000	1,95,600	21.9%	Short covering

The activity column is the four-quadrant reading of the premium change against the open-interest change — it classifies what the two numbers did together, nothing more.

Option Price Calculator

Every listed strike priced side by side, with what the position would cost per lot and what it becomes at the level you set.

Example output from the Option Price Calculator. Illustrative figures, not market data.
Moneyness	Strike	Today (LTP)	Lot cost	IV	Cycle end (est)	Change / lot
ITM	2,400	118.40	29,600	23.4%	186.20	+16,950
ITM	2,450	84.15	21,038	22.8%	142.75	+14,650
ATM	2,500	56.70	14,175	22.1%	104.30	+11,900
OTM	2,550	34.25	8,563	21.7%	72.60	+9,588
OTM	2,600	19.80	4,950	21.9%	47.15	+6,838

Pricing is Black-Scholes on the stored spot and implied volatility. The cycle-end column is an estimate produced by the model, not a quote.

FII / DII Data

Foreign and domestic institutional buying, selling and net flow in the cash market, one row per session.

Example output from the FII / DII Data. Illustrative figures, not market data.
Date	FII buy	FII sell	FII net	DII net
12 Jun 2025	14,206.80	15,874.30	−1,667.50	+2,104.60
11 Jun 2025	12,918.40	11,655.10	+1,263.30	−842.90
10 Jun 2025	16,331.70	18,002.50	−1,670.80	+1,988.20
09 Jun 2025	11,447.20	10,914.60	+532.60	−316.40

Published by the exchanges after the close and not revised afterwards, which is what makes a figure from two years ago directly comparable with last week's.

(Scanner) Candlestick Patterns

Every candlestick formation that completed on the stock inside your window, with how cleanly it formed and what the studied reversal rate for that pattern is.

Example output from the (Scanner) Candlestick Patterns. Illustrative figures, not market data.
Date	Pattern	Group	Direction	Strength	Reversal rate
06 Jun 2025	Bullish Engulfing	Two candle	bullish	82	63%
28 May 2025	Hammer	Single candle	bullish	74	60%
19 May 2025	Evening Star	Three candle	bearish	88	72%
07 May 2025	Doji	Single candle	neutral	61	—

Direction is what the measured data says about the formation, which is not always what the textbook name implies. Strength describes the formation only — it is not a probability.

(Scanner) Multi-Timeframe Candlestick Patterns

Only the stocks where the monthly, weekly and daily candles all printed a formation in the same direction.

Example output from the (Scanner) Multi-Timeframe Candlestick Patterns. Illustrative figures, not market data.
Stock	Monthly	Weekly	Daily	Strength
EXAMPLE A	Bullish Engulfing	Hammer	Piercing Line	79
EXAMPLE B	Morning Star	Bullish Engulfing	Hammer	86
EXAMPLE C	Hammer	Morning Star	Bullish Engulfing	71

The list is short by construction: each extra timeframe that has to agree removes most of the candidates. Weekly and monthly candles are aggregated from stored daily history, so each carries that period's summed volume.

(Scanner) Multi-Timeframe Chart Patterns

Stocks carrying the same kind of chart shape on all three timeframes — head and shoulders, double tops, wedges, triangles, harmonics.

Example output from the (Scanner) Multi-Timeframe Chart Patterns. Illustrative figures, not market data.
Stock	Monthly	Weekly	Daily	Fit
EXAMPLE A	Ascending Triangle	Falling Wedge	Double Bottom	77
EXAMPLE B	Double Bottom	Ascending Triangle	Falling Wedge	84
EXAMPLE C	Falling Wedge	Double Bottom	Ascending Triangle	69

Chart patterns take dozens of bars to draw, so a monthly one spans years. Fit scores how near the measured leg ratios sit to the textbook proportions — it measures the drawing, not the outcome.

Option Strategy Backtester

Every past expiry the strategy would have traded, replayed one cycle at a time, with what each one made or lost and the path it took.

Example output from the Option Strategy Backtester. Illustrative figures, not market data.
Expiry	Entered	Days held	Spot move	P&L	MAE	MFE
26 Jun 2025	29 May 2025	28	+3.4%	+12,450	−4,200	+16,100
29 May 2025	24 Apr 2025	35	−1.8%	−6,300	−9,750	+2,400
24 Apr 2025	27 Mar 2025	28	+5.1%	+18,900	−1,850	+21,300
27 Mar 2025	27 Feb 2025	28	+0.6%	+2,150	−7,400	+5,900

MAE and MFE are the worst and best the position reached while open, reported because two cycles that closed at the same figure can have taken very different routes there.
