Three Drives Pattern: Fibonacci 127.2% and 161.8% Levels Explained with a Reliance Example

What the Three Drives Pattern Actually Is

The Three Drives Pattern is a technical analysis reversal pattern made of three consecutive pushes, called drives, in the same direction, separated by two pullbacks. A bearish Three Drives makes three higher highs into a top and then reverses down. A bullish Three Drives makes three lower lows into a bottom and then reverses up. The pattern is part of the harmonic family popularised by Larry Pesavento and Scott Carney, so it lives and dies by Fibonacci measurement, not by eyeballing.

The single rule that makes this pattern valid is the extension rule. Each new drive must terminate at a Fibonacci extension of the move before it, and the standard extension levels are 127.2% and 161.8%. If the third drive overshoots far past the 161.8% level or stops well short of 127.2%, the symmetry is broken and the pattern is unreliable. This is exactly where most shallow guides go wrong. They show three round numbers like Rs 120, Rs 130 and Rs 140 that have no Fibonacci relationship at all, so a reader cannot actually reproduce or trust the setup.

In Indian markets the pattern shows up on liquid names like Reliance, HDFC Bank, Infosys and TCS, and on indices like Nifty and Bank Nifty, across intraday, daily and weekly charts. Liquidity matters because the Fibonacci levels need clean swings to measure from, and thin stocks produce noisy, gappy drives that you cannot measure with any confidence.

The Anatomy of the Two Retracements and Three Drives

Walk the structure point by point. Start at the pattern origin, label it X. Price pushes up to the first drive high, call it Drive 1. It then pulls back to a retracement low, Retracement A. From there it pushes to a higher high, Drive 2, which should sit at the 127.2% or 161.8% extension of the first leg measured from Retracement A. Price pulls back again to Retracement B, then pushes to the final higher high, Drive 3, which again must land at the 127.2% or 161.8% extension of the second leg measured from Retracement B. The reversal trade is taken when Drive 3 completes and price starts to roll over.

The two retracements between the drives carry their own rule of thumb. In a clean pattern each pullback retraces roughly 61.8% or 78.6% of the prior drive. If the first pullback is shallow and the second is deep, or the drives are wildly different in length, the symmetry is gone and you should pass. Symmetry in time matters too. If Drive 1 took five candles, Drive 2 should take a similar number, not twenty. A pattern that is lopsided in time is usually just an ordinary trending leg, not a Three Drives top.

• X: the origin, the swing low (bearish setup) or swing high (bullish setup) where the pattern begins.
• Drive 1: the first push that sets the initial leg you will measure from.
• Retracement A: the first pullback, ideally 61.8% to 78.6% of Drive 1.
• Drive 2: terminates at the 127.2% or 161.8% extension of leg 1, projected from Retracement A.
• Retracement B: the second pullback, again ideally 61.8% to 78.6% of the second drive.
• Drive 3: terminates at the 127.2% or 161.8% extension of leg 2, projected from Retracement B. This is your reversal zone.

How to Calculate the 127.2% and 161.8% Levels

The two extension multipliers are not arbitrary. 1.272 is the square root of 1.618, and 1.618 is the golden ratio itself. To project a drive target you take the length of the prior impulse leg, multiply it by 1.272 or 1.618, and add that distance to the retracement low (for a bearish pattern) where the next drive begins. The formula for a bearish drive target is simply: Drive target = Retracement low + (extension multiplier multiplied by the prior leg length).

Most charting platforms used in India, including Zerodha Kite, Upstox, TradingView and Fyers, have a built in Fibonacci extension or trend based Fib extension tool that does this for you. You anchor it on the three points of the prior swing, and the platform plots the 1.272 and 1.618 lines automatically. The worth of knowing the manual formula is that you can sanity check the platform and confirm the third drive is landing where the rule says it should, instead of trusting that three higher highs by themselves mean anything.

Worked Example: A Bearish Three Drives on Reliance Anchored to Real Fibonacci Prices

Here is the part that the old version of this page got wrong. Instead of three round numbers, we will build the pattern from actual Fibonacci math so every drive sits on a price you can verify. All levels below are illustrative and chosen to show the calculation cleanly. Imagine Reliance Industries on a swing chart. The pattern origin X is at Rs 1380. Drive 1 pushes to Rs 1440, so the first leg is 1440 minus 1380, which is 60 points. Price then pulls back to Retracement A at Rs 1416, a 40% pullback of that leg, which is acceptable though on the shallow side.

Now project Drive 2. The 127.2% extension of leg 1 from Retracement A is 1416 plus (1.272 multiplied by 60), which equals Rs 1492.3. Drive 2 prints almost exactly there at Rs 1492, confirming the first extension. Price pulls back to Retracement B at Rs 1466. The second leg, from Retracement A to Drive 2, is 1492 minus 1416, which is 76 points. Project Drive 3: the 127.2% extension of leg 2 from Retracement B is 1466 plus (1.272 multiplied by 76), which equals Rs 1562.7. The deeper 161.8% target would be 1466 plus (1.618 multiplied by 76), which equals Rs 1589.0.

Drive 3 stalls at Rs 1563, landing right on the 127.2% extension, and a bearish reversal candle forms. That confluence, a higher high sitting on a precise Fibonacci extension with a reversal candle, is the actual signal. A trader shorts near Rs 1563 with a stop just above the 161.8% level at Rs 1589, since a clean break above 1589 invalidates the pattern. The first target is a return to the Retracement B area near Rs 1466, and a fuller target is a return toward the origin near Rs 1400.

The Same Trade in Rupees: Cash Short vs Put Option

Say price falls from the Rs 1563 entry to Rs 1505, a 58 point drop, before you exit. The table below shows two ways an Indian trader could have expressed this bearish Three Drives reversal: an intraday cash short of 200 shares, and a put option using Reliance F&O. Note that you cannot short equity delivery overnight in India, so a cash short here is intraday only, squared off the same day. The option route lets you hold longer and caps your risk at the premium paid. All figures are illustrative and use rough discount broker costs.

Two things stand out. First, the option pays more here because one lot is 500 shares versus the 200 shares in the cash example, and the put gained value quickly as the stock fell, so do not read this as the option always winning. If price had stalled instead of falling, time decay would erode the put while the cash short would simply have been squared off near breakeven. Second, costs are real. STT on options is charged at 0.10% on the sell side of the premium since the October 2024 revision, and STT on intraday equity is 0.025% on the sell value. These plus brokerage and GST are why net is always less than gross.

Taxes on Three Drives Trades in India

How your profit is taxed depends on how you traded the pattern. F&O trading is treated as business income, not capital gains, so the put option profit above is added to your business income and taxed at your applicable slab rate. You can also set off F&O losses against most other income heads, and you may need a tax audit if your turnover crosses the prescribed threshold. Keep a clean trade log, because business income filing for F&O requires you to report turnover and profit, not just net gains.

If you instead bought the stock on a bullish Three Drives bottom and held it, capital gains rules apply. Short term capital gains on listed equity held under one year are taxed at 20%, raised in the July 2024 budget from the old 15%. Long term capital gains above Rs 1.25 lakh in a financial year are taxed at 12.5%, with the first Rs 1.25 lakh exempt. An intraday cash short, like the Reliance short above, is speculative business income, taxed at slab rates, and is reported separately from delivery based capital gains.

• F&O profit or loss: business income, taxed at your slab rate, losses can be carried forward and set off, audit may apply above the turnover threshold.
• Intraday equity (the cash short): speculative business income, taxed at slab rates.
• Delivery equity held under 1 year: STCG at 20%.
• Delivery equity held over 1 year: LTCG at 12.5% on gains above Rs 1.25 lakh per year.

Confirming the Pattern with Volume, RSI and Divergence

A Three Drives pattern is far stronger when momentum is fading into the third drive. The single most useful confirmation is bearish divergence on the Relative Strength Index. If Drive 3 makes a higher high in price but RSI makes a lower high, momentum is weakening even as price pushes up, which is exactly the condition you want before shorting a top. In the Reliance example, an RSI reading rolling over from overbought near 70 as price tagged Rs 1563 would have added real conviction to the short.

Volume tells a similar story. In a healthy bearish Three Drives, volume often declines across the three drives, showing that fewer buyers are willing to chase each successive high. A reversal candle on Drive 3 backed by a surge of selling volume is a strong tell. Pair these with a moving average for trend context, and you have a multi factor confirmation stack rather than a single pattern guess. The pattern gives you the location, the indicators give you the timing.

Three Drives vs Related Reversal Patterns

Traders often confuse Three Drives with other reversal structures because they look superficially similar. The table below separates them. The key difference is that Three Drives is strictly Fibonacci defined and symmetrical, whereas a Head and Shoulders is defined by relative peak heights and a neckline, and a rising wedge is defined by converging trendlines rather than extension targets.

Three Drives also shares its Fibonacci DNA with Elliott Wave theory, where a five wave impulse and the golden ratio recur constantly. You do not need full Elliott Wave knowledge to trade Three Drives, but understanding that markets repeatedly respect the 0.618 and 1.618 ratios explains why these extension levels work often enough to be tradable.

Common Mistakes That Wreck the Setup

The most damaging mistake is calling three higher highs a Three Drives pattern without measuring the extensions. If the drives do not land near 127.2% or 161.8%, you do not have the pattern, you just have a trend, and shorting a strong trend because it made three highs is a fast way to lose money. The Reliance example only became a trade because Drive 3 sat on the verified Rs 1562.7 extension, not merely because it was the third high.

The second common error is ignoring market context and event risk. A Three Drives top printing the day before an RBI policy decision, Reliance earnings, the Union Budget or a major US Federal Reserve announcement can be blown apart by a gap. Indian weekly index options expire on set weekly days and monthly contracts on the last applicable day of the month, so an options based Three Drives trade held into expiry faces accelerating time decay. Size for the event, tighten stops, or stand aside.

• Skipping the Fibonacci check and trading any three higher highs as a pattern.
• Forcing symmetry that is not there: very unequal drive lengths or very different pullback depths.
• Shorting at Drive 3 with no stop above the 161.8% invalidation level.
• Holding an option based setup into an event or into expiry week without accounting for time decay.
• Risking more than a small, fixed fraction of capital on a single pattern, however clean it looks.

A Practical Checklist Before You Take the Trade

Treat the pattern as a setup, not a signal. The setup tells you where to look. The signal is the reversal confirmation. Run this checklist before committing capital, and write the trade and its outcome into your trading journal so you can measure how often the pattern actually works for you on the instruments you trade. Edge comes from data on your own results, not from a textbook hit rate.

• Are all three drives landing near 127.2% or 161.8% extensions of the prior leg? If not, pass.
• Are the two pullbacks similar in depth (around 61.8% to 78.6%) and the drives similar in time? Symmetry confirms the pattern.
• Is there momentum divergence on RSI and ideally fading volume into Drive 3?
• Has a reversal candle actually formed, or are you anticipating one? Wait for it.
• Is your stop placed beyond the 161.8% invalidation level, and is your position sized so that stop costs only a small, fixed fraction of capital?
• Is there a major event (RBI, budget, earnings, expiry) within your holding window? Adjust or stand aside.
