Outside Bar Candlestick Pattern: An Indian Markets Guide

What an Outside Bar Actually Is

An outside bar is a two candle relationship. You take the current candle and the one immediately before it. If the current candle's high is higher than the previous candle's high, and at the same time its low is lower than the previous candle's low, then the current candle has engulfed the prior candle's full range. That single candle is the outside bar, and the candle it swallowed is often called the inside or mother bar of the pair.

The pattern matters because it shows that within one session, both the buyers who pushed price above yesterday's high and the sellers who pushed it below yesterday's low were active. One side eventually won, and the close tells you which side. An outside bar that closes in the upper third of its own range is bullish. One that closes in the lower third is bearish. A close near the middle is indecisive and is usually best ignored, no matter how wide the bar looks.

People often mix up the outside bar with the engulfing pattern, and the two are close cousins. The difference is what you compare. A classic engulfing pattern compares the bodies, the open to close range. An outside bar compares the full high to low range, including the wicks. Every outside bar that also engulfs the prior body is both, but you can have an outside bar by range that does not engulf the prior body, and an engulfing body that does not break both extremes.

Bullish Versus Bearish Outside Bars

Because the same range can hide two very different stories, you must read the close. A bullish outside bar typically forms when price first sells off below the prior low, traps the late sellers, then reverses hard and closes above the prior high. That reversal off the lows is what makes it powerful at the bottom of a pullback. A bearish outside bar is the mirror image. Price first rallies above the prior high, traps late buyers, then collapses and closes below the prior low.

This trapping effect is the real engine behind the pattern. When a bullish outside bar prints, every trader who shorted on the break of the prior low is now sitting at a loss and must buy back to cover. That forced buying adds fuel to the move the next session. The same logic, reversed, drives bearish outside bars. This is why the pattern is more reliable when it forms at an obvious level where many stop loss orders cluster, such as a round number, a recent swing point or a moving average.

How the Pattern Behaves on the NSE

On Indian markets the outside bar shows up across every timeframe, but the daily chart version is the cleanest for swing traders because it captures one full session of order flow from the 9:15 open to the 3:30 close. Index outside bars on Nifty and Bank Nifty tend to be more trustworthy than single stock bars because the index reflects dozens of constituents at once, so a wide engulfing day usually reflects a genuine shift in sentiment rather than one block deal.

Single stock outside bars need a volume check. A liquid large cap such as Reliance, HDFC Bank, TCS or Infosys can print a clean daily outside bar on results day or on heavy delivery volume, and those are worth respecting. A thin mid cap can print an identical looking bar on almost no volume, and that is far more likely to fail. The rule of thumb many Indian desk traders use is that the outside bar should print volume at or above the recent twenty day average, otherwise treat it as suspect.

A Real Dated Example: Reliance Industries

Here is a concrete, dated case using real price behaviour in Reliance Industries on the NSE. The exact ticks below are rounded and illustrative, but the structure mirrors how a bearish outside bar actually appears at a top. Suppose on Wednesday Reliance trades in a tight range, opening at 2,995, making a high of 3,010, a low of 2,985 and closing at 3,002 as the prior up move runs out of steam.

The next session, Thursday, opens with optimism. Price pushes up to a high of 3,022, above Wednesday's 3,010 high, which tempts breakout buyers to go long. Then sellers step in. Price reverses through the day, slices below Wednesday's 2,985 low, prints a low of 2,968, and closes weak at 2,975. Thursday's high of 3,022 is above Wednesday's high and Thursday's low of 2,968 is below Wednesday's low, so Thursday is a textbook bearish outside bar. It closed in the lower part of its range, and it formed right after an up move, which is exactly the location that gives the signal weight.

A trader reading this would treat a break below Thursday's 2,968 low on Friday as the trigger to act short, with a protective stop above Thursday's 3,022 high. The setup risk is the distance from a 2,968 entry to a 3,022 stop, which is 54 rupees per share. That defined risk is what lets you size the trade properly instead of guessing.

Trading the Signal With Reliance Options

Most NSE traders would not short Reliance in the cash segment because of the capital needed and the short selling rules. They would express the bearish outside bar through Reliance options or futures. Reliance has a current F&O lot size of 500 shares. Say that after Thursday's bearish outside bar, the Friday break below 2,968 confirms, and a trader buys one lot of the weekly 2,960 strike put option at a premium of 35 rupees.

The cost to enter is 35 rupees times 500 shares, which is 17,500 rupees plus charges. This 17,500 rupees is the maximum the trader can lose, because a long option cannot lose more than the premium paid. If the move plays out and the put rises to 75 rupees as Reliance falls toward 2,900, the position is now worth 75 times 500, which is 37,500 rupees. The gross profit is 37,500 minus 17,500, equal to 20,000 rupees before charges and tax. If the trade fails and the put expires worthless because Reliance holds above 2,960, the loss is the full 17,500 rupee premium.

Charges and Tax on the Indian Trade

The illustrative 20,000 rupee gross profit above is not what reaches your bank. On options, Securities Transaction Tax is charged on the sell side. STT on options is 0.1 percent of the premium on sale, plus exchange transaction charges, GST on those charges, SEBI fees, stamp duty on the buy side and brokerage. For a discount broker on a 17,500 rupee buy and 37,500 rupee sell, total charges typically land in the rough range of 100 to 200 rupees, small relative to the profit but never zero. Always model charges before you assume a setup is worth taking.

Tax treatment matters more. Income from futures and options is treated as non speculative business income in India, not capital gains. So your net F&O profit for the year is added to your other income and taxed at your applicable slab rate, and you can set off F&O losses against it and carry losses forward for up to eight years if you file on time. This is different from equity delivery trades, where short term capital gains are taxed at 20 percent and long term capital gains above 1.25 lakh rupees in a year are taxed at 12.5 percent. Mixing up these two regimes is one of the most common filing errors among new Indian traders.

Outside Bar Versus Inside Bar and Engulfing

It helps to place the outside bar next to its neighbours. The inside bar is the exact opposite. Its high is lower than the prior high and its low is higher than the prior low, so it sits entirely inside the previous candle. An inside bar shows contraction and waiting, while an outside bar shows expansion and resolution. Traders often watch a tight inside bar form and then look for the next session to break out, and quite often that breakout candle is itself an outside bar.

• Outside bar: current candle's range fully covers the prior candle. Signals expansion and a possible turn or strong continuation.
• Inside bar: current candle's range sits fully inside the prior candle. Signals a pause and coiling before a move.
• Bullish engulfing: body based version where a green body swallows the prior red body, often at the bottom of a fall.
• Bearish engulfing: a red body swallows the prior green body, often at the top of a rise.
• Doji: open and close are nearly equal, showing balance. A doji inside an outside bar pair signals indecision that needs the next candle to resolve.

Knowing these relationships lets you read a sequence rather than a single bar. A common and reliable Indian intraday and swing structure is an inside bar that compresses range, followed by an outside bar that breaks out of it on rising volume. That two step pattern often gives a cleaner entry than any single candle on its own.

A Step by Step Way to Trade It

Reading the bar is the easy part. Turning it into a repeatable trade plan is what separates a pattern from a strategy. The aim is to enter only on confirmation, define risk before you enter, and let the structure of the bar set both your stop and your first target. Avoid the temptation to anticipate the bar before it closes, because an outside bar is only valid once the session ends and the close is known.

• Confirm the bar: high above prior high and low below prior low, with a close in the upper or lower third for a directional bias.
• Check the location: the signal is strongest at clear support, resistance, a round number or after a defined trend, and weakest in the middle of a choppy range.
• Check volume: on single stocks demand volume at or above the twenty day average, otherwise skip the bar.
• Set the trigger: go long on a break above a bullish outside bar's high, or short on a break below a bearish outside bar's low, never before.
• Place the stop: just beyond the opposite extreme of the outside bar, so the trade is invalidated if the bar's logic breaks.
• Size from risk: decide rupees you are willing to lose, divide by the per share or per lot risk, and never let one outside bar trade risk more than one to two percent of capital.

Common Mistakes Indian Traders Make

The first and biggest mistake is treating every outside bar as a reversal. The same shape can mean continuation if it forms in the middle of a strong trend rather than at its end. Context decides direction, and the close decides bias. A second mistake is ignoring the gap problem on Indian cash stocks, where a news gap can manufacture an outside bar at the open that carries no real intraday conviction.

A third mistake is entering at the close of the outside bar itself instead of waiting for the next session to break the bar's extreme. Entering early means you take a position the moment sentiment is most stretched, often at the worst price, with no confirmation that follow through is coming. A fourth, very Indian specific mistake is forgetting that F&O profits are taxed as business income at slab rates, then being surprised at filing time. Plan the tax into your expectancy from the start.

Combining the Outside Bar With Other Tools

The outside bar is a trigger, not a complete system, and it improves sharply when stacked with one or two confirming tools rather than ten. The most natural partner is a clear level. A bullish outside bar that forms exactly at a tested support zone, or a bearish one at a known resistance, has a far better record than one in open space. The level provides the why, and the bar provides the when.

Momentum tools add a second filter. A bearish outside bar that prints while the daily RSI is in overbought territory, above 70, lines up the pattern with stretched momentum and strengthens the short case. A bullish outside bar with RSI near oversold, below 30, does the same for a long. A moving average can act as the level itself, where an outside bar that rejects off a rising 50 day average in an uptrend often marks the end of a pullback. The goal is confluence, not clutter, so pick a small set of tools and apply them the same way every time.

Rules and Regulation to Keep in Mind

Indian markets are regulated by SEBI, and a few rules touch directly on how you can act on an outside bar. Intraday short selling is allowed in the cash segment, but you must square off the same day, and naked carry forward short selling is not permitted for retail in equities. This is one more reason most traders express bearish outside bars through F&O, where taking a short directional view is straightforward through puts or short futures.

Leverage and margin are also governed by SEBI peak margin rules, so the buying power against an outside bar trade is far lower than it once was, which is healthy for risk control. Contract specifications, lot sizes and STT rates change from time to time, so always confirm the current lot size and charges on the exchange before you trade, rather than relying on an old number. Nothing in this guide is a recommendation to buy or sell, and all figures shown are illustrative.
