What is it
What is a Fibonacci retracement calculator?
A Fibonacci retracement calculator turns a swing High and swing Low into a set of reference price levels: retracement levels inside the range where a pullback might pause, and extension levels beyond the range where a continuation move might target. Intraday and F&O traders on the NSE and BSE use these levels alongside price action to plan entries, exits and stop-losses.
Unlike moving averages or oscillators that recompute as new candles form, Fibonacci levels are fixed once the swing High and Low are chosen, giving you a static map to trade against for that move.
Formula
How the levels are calculated
Every level comes from the same two inputs, the swing High and swing Low, scaled by a Fibonacci ratio. Only the direction of the formula changes with the trend.
Retracement ratios: 0%, 23.6%, 38.2%, 50%, 61.8%, 76.4%, 100%. Extension ratios: 138.2%, 161.8%, 200%, 261.8%.
How to use it
4 steps to use this calculator
- Mark the swing High and swing LowIdentify a clear recent swing High and swing Low on your chart for NIFTY, BANKNIFTY or any NSE/BSE-listed stock.
- Pick the trend directionChoose Uptrend if price moved Low to High and you're expecting a pullback, or Downtrend if price moved High to Low and you're expecting a bounce.
- Read the retracement and extension levelsThe calculator returns standard ratios as exact price levels.
- Plan entries, targets and stop-lossesUse the levels as reference zones, then watch for price action, volume or candlestick confirmation before acting.
Levels explained
What each Fibonacci ratio means
Seven retracement ratios and one extension band, from the start of the move to well beyond it.
0%
The starting point of the retracement, anchored at the swing High in an uptrend or the swing Low in a downtrend.
23.6%
A shallow pullback. In a strong trend, price often barely touches this level before continuing.
38.2%
A moderate retracement, common in trending markets where the prior move still has momentum left.
50%
Not a true Fibonacci ratio, but included because markets frequently retrace almost exactly half of a move.
61.8%
The golden ratio and the most closely watched level. A bounce here is often read as the trend resuming.
76.4%
A deeper retracement. A pullback this far starts to raise doubt about whether the original trend is still intact.
100%
The full retracement, back to the swing Low in an uptrend or swing High in a downtrend.
138.2% - 261.8%
Extension levels beyond the swing range, used as potential profit targets past the prior High or Low.
Trading with Fibonacci
Reading Fibonacci levels like a trader
Buying a pullback in an uptrend
When price retraces to the 38.2%-61.8% zone and holds with a bullish reversal candle, some traders treat it as a lower-risk entry back in the direction of the original uptrend.
Selling a bounce in a downtrend
A bounce into the 38.2%-61.8% zone that stalls and reverses is watched as a potential re-entry point in the direction of the original downtrend.
Confluence with other levels
A Fibonacci level that lines up with a pivot point, moving average or a prior support/resistance zone is generally given more weight than one standing alone.
Extensions as profit targets
Once price breaks past the swing High or Low, the 138.2% and 161.8% extension levels are commonly used as the next targets to book partial or full profit.
FAQ
Frequently asked questions
What is Fibonacci retracement in trading?
Fibonacci retracement is a technical analysis tool that marks potential support and resistance levels between a swing High and swing Low, based on ratios drawn from the Fibonacci sequence: 23.6%, 38.2%, 50%, 61.8% and 76.4%. Traders watch these levels for where a pullback might pause or reverse before the prior trend resumes.
How are Fibonacci retracement levels calculated?
For an uptrend: level = High - (High - Low) x ratio, so 0% sits at the High and 100% sits at the Low. For a downtrend: level = Low + (High - Low) x ratio, so 0% sits at the Low and 100% sits at the High. Only the swing High, swing Low and trend direction are needed.
What is the difference between retracement and extension levels?
Retracement levels from 0% to 100% sit inside the original swing High-Low range and mark where a pullback might end. Extension levels, including 138.2%, 161.8%, 200% and 261.8%, project beyond the range in the direction of the original trend and are used as potential profit targets.
Which Fibonacci level is the most important?
61.8% is called the golden ratio and is the most closely watched retracement level, followed by 38.2% and 50%. A pullback that holds near 61.8% and resumes the prior trend is one common pattern traders look for, though it is not guaranteed.
Should I calculate Fibonacci levels for an uptrend or a downtrend?
Use uptrend when price has moved from a swing Low up to a swing High and you expect a pullback down before the trend continues higher. Use downtrend when price has moved from a swing High down to a swing Low and you expect a bounce up before the trend continues lower.
Do Fibonacci levels guarantee support and resistance?
No. They are reference zones based on historical price behaviour, not a guarantee. Price can pass through a Fibonacci level without reacting at all. Many traders confirm a level with candlestick structure, volume or another indicator before acting on it.
What time frame works best for Fibonacci retracement?
Fibonacci retracement works on any time frame, from 5-minute intraday charts to weekly swing charts. The levels are more widely watched, and therefore more likely to matter, on higher time frames and liquid instruments such as NIFTY, BANKNIFTY and large-cap F&O stocks.
Fibonacci levels are a technical reference derived from historical price and do not guarantee future price behaviour. Use them alongside your own risk management, not as a substitute for it.
