Option Trendlines

What this tab finds

Option Trendlines asks the Trendline Support question of an option's own price. A trendline is a straight line through at least two (here, by default, three) turning points of a chart. Instead of drawing it on the stock, this tab draws it on the premium - the price you pay for the option - and lists every contract whose premium is sitting on such a line right now.

One row is one contract, not one stock. RELIANCE alone has calls and puts at three strikes over two expiries, so a stock can appear on several rows at once. The lines are fitted on five charts of the premium: 15 min, 1 hour, 2 hour, 4 hour and Daily. There is no weekly or monthly chart, because a monthly contract lives about three months and trades actively for only the last one or two.

• Support: a line under the premium that it has bounced from before.
• Resistance: a line over the premium that has turned it down before.
• Call (CE): an option that gains when the underlying rises. Put (PE): one that gains when the underlying falls.
• Premium: the option's last traded price. Every line on this tab is drawn on it.

Keep in mind. A premium also loses a little value every day as expiry comes closer (time decay). That slow slide is part of every falling line on this tab - a falling resistance on a premium is partly the calendar, not only sellers.

Which contracts are scanned, and how fresh they are

Not every option is scanned - only the strikes that hold most of the trading, near the underlying's price. The Market control picks one of three groups; each has its own file and its own clock.

The line over the table ends with "as of" and the time of the newest candle in the file. Check it before you act: if the engine had no broker session, nothing refreshes and the last file stays.

Tip. The sidebar's universe is a list of stocks, so it narrows the Stocks market and nothing else. If a stock option you expect is missing, pick a wider universe - Nifty F&O holds every F&O stock.

Reading a row

Every column header can be clicked to sort by it; click again to flip the order. The default order is TFs, most first, then the most-touched line, then the nearest.

Tip. Right-click a row to add the contract itself to a watchlist; the menu offers the stock behind it too.

The controls

Every control is saved in the page address, so a narrowed view can be bookmarked, shared, or kept with Save scan.

Tip. If the table is empty, the page tells you what to loosen: widen Within, drop to ×2 touches, allow retests, or clear the column filters.

Column filters (the row under the headers)

Under eight of the headers - At support, Sup shape, At resistance, Res shape, Pattern, TFs, Touches and Dist - sits a filter box, the same one Trendline Support uses. Timeframe and shape boxes take several picks at once; number boxes take one cut.

• At support / At resistance: pick 1D to keep contracts with a daily line; pick several to keep any of them; Not on any keeps contracts with no line on that side.
• Sup shape / Res shape: Rising, Floor or Falling (Ceiling for resistance).
• Pattern: one of the seven named figures.
• TFs: 2 or more ... 5 or more, or Exactly 1.
• Touches: 3 or more ... 6 or more.
• Dist: Within 0.25%, Within 0.5%, Within 1%, Above the line, Below the line.

The line over the table counts how many column filters are on. Clear them all in one go from the empty-table message, or open each box and empty it.

Timeframes and 'touching' on a premium

The five charts are 15 min, 1 hour, 2 hour, 4 hour and Daily. Daily candles are built from the contract's own 15-minute bars. Because option contracts are young, a chart needs less history here than on a stock: about 60 candles on 15 min, 40 on 1 hour, 30 on 2 hour and 15 on 4 hour and daily. A new contract may have no daily or 4-hour lines yet.

Touching is measured in the chart's own average range (ATR), not in per cent. On a premium that range is large, so a line the engine calls touching can be several per cent away - that is why Within offers 2% to 20% rather than the small steps on Trendline Support.

Keep in mind. A Dist of -4.80% on a premium is not the same as -4.80% on a stock. Read Dist together with the chart: the popup draws the line, so you can see whether it is one candle's wobble away.

The option chart (click a contract)

Clicking a contract opens the premium's own candle chart - not the stock's. It opens on the Timeframe you picked, or else on the chart carrying the row's nearest line. It uses the site's one chart, so most of the chart guide applies; the differences are listed here.

• Fewer speeds: the strip offers only the five option timeframes (15 min to Daily). There is no weekly or monthly chart of a premium.
• No stock layers: the Layers panel has no On the chart group - no averages, levels, major zones, 52-week marks, coils or round numbers. Those describe a stock's price and mean nothing on a premium. It keeps Trendlines from, limited to the five option timeframes.
• The line the row named is drawn even when it is a retest, which the default Current view would hide.
• The title counts the lines drawn at your touch count, e.g. "3 lines at ×3+". Under the chart: how many candles, since when, and as of when.
• TradingView: the button links out when the contract has a TradingView name; Copy lines for TradingView copies a small script with this chart's lines.

1. Click the contract name in the Option column.
2. Use the Lines switch to choose Current, + Retests or All.
3. Step through 15 min ... Daily on the strip to see each chart's own lines.
4. Open Layers and tick a slower timeframe under Trendlines from to lay its lines on this chart.

Tip. Everything else - zoom, drawing, Heikin-Ashi, saving a default - is in the chart guide.

Line states and patterns

Scenarios, step by step

Each scenario uses real rows from 2 Oct 2026 (a market holiday; the files held data as of the 1 Oct close). Numbers will have moved by the time you read this.

1. A call on rising support (the bullish read on a premium).

1. Set Type to Calls (CE) and Line to Support.
2. Open the Sup shape filter and pick Rising.
3. Sort by Touches to put the best-tested lines first.
4. Click a contract and check the line on its own timeframe; then step one speed slower.

2. A put pressing on resistance.

1. Set Type to Puts (PE) and Line to Resistance.
2. Set On at least to 2 timeframes, so one chart alone is not enough.
3. Read the At resistance chips: solid chips are intact lines; dashed ones are retests.

3. Index options.

1. Set Market to Indices.
2. Use Expiry to tick only the monthly or only next week's contracts.
3. Remember the index file refreshes every 15 minutes in the session; check the as-of time in the summary line.

4. Expiry-week caution.

1. With Market on Indices, tick only the nearest expiry under Expiry.
2. Compare Chg across the rows: in expiry week premiums can halve or nearly double in a session.
3. Treat 15-minute and 1-hour lines here as short-lived; a contract days from expiry has little history and fast time decay.

5. One stock's options only.

1. Click the stock in the left pane (or add ?un= and the symbol to the address).
2. The table narrows to that stock's contracts; the summary line says "AXISBANK only" with a show every option link.
3. If nothing shows, either the stock is not in F&O or none of its contracts is on a line - widen Within or drop to ×2.

6. A daily line on a premium.

1. Set Timeframe to Daily.
2. Read Dist with care: on a daily premium chart, touching can be 10% away.
3. Open the contract, then lay the daily line on the 1-hour chart through Layers > Trendlines from.

What this tab does not tell you

• It does not say the premium will bounce or break. A line is where the premium turned before; the tab finds it, it does not forecast it.
• It does not show option Greeks, implied volatility or the bid-ask spread. Check the spread in your broker before trading a contract with low OI or volume.
• It scans only the strikes near the money and two expiries. A far strike you trade may not be here at all.
• Prices are as of the last refresh shown in the summary line, not live ticks.
• Time decay is inside every line. A falling line on a premium can be the calendar alone.
• A support on a call and a resistance on the matching put are often the same move of the underlying seen twice; they are not two independent signals.

Keep in mind. Options can lose most of their value quickly, especially near expiry. Nothing on this tab is a recommendation to buy or sell any contract.
