Introduction
In this article we’ll explore the Fibonacci Bands indicator, originally developed by Bigbeluga. This tool blends volatility (via ATR), a smoothed moving average (SMMA) and key Fibonacci ratios to help traders identify dynamic support/resistance zones and potential “liquidation sweeps.”
We’ll cover how it works, how to interpret its signals, how to configure its inputs, and best practices for integrating it into your trading.
Overview of the Indicator
Fibonacci Bands consist of six dynamic lines plotted around a Smoothed Moving Average (SMMA). The distance of each band from the SMMA is set by multiples of the Average True Range (ATR) scaled by Fibonacci ratios:
- Band 1 (38.2 %): ATR × 1.618
- Band 2 (61.8 %): ATR × 2.618
- Band 3 (100 %): ATR × 4.236
These bands are coloured and projected forward, giving you:
- Volatility measurement through an ATR smoothed over 200 bars.
- Trend filtering via a SMMA of price.
- Fibonacci-based zones that act as dynamic support/resistance.
Suitable for any timeframe, it excels in impulsive trends and clear ranging markets, offering both entry/exit cues and zones for potential continuations or retracements.
How to Interpret the Bands
- Upper and lower bands
- fibtop1 / fibbot1 mark the 38.2 % level (ATR × 1.618).
- fibtop2 / fibbot2 mark the 61.8 % level (ATR × 2.618).
- fibtop3 / fibbot3 mark the 100 % level (ATR × 4.236).
- Zone colouring
- The area between the middle and outer bands (levels 2→3) is painted red above the SMMA and green below it, highlighting dynamic overbought/oversold regions.
- Liquidation sweeps
- Local pivot highs/lows are identified (leftbars = 4, rightbars = 1).
- When price touches or exceeds the outer band (fibtop3/fibbot3) and “sweeps” stops against the trend, a red or green dot marks potential stop-hunt zones before a reversal.
Entry and Exit Signals
- Bearish sweep (sweep Down)
- SMMA is declining (downtrend).
- A new pivot high breaches fibtop3.
- High crosses below the prior bar’s high.
- A red point is drawn above the bar.
- Confirmation via a horizontal segment at the pivot level.
- Bullish sweep (sweep Up)
- SMMA is rising (uptrend).
- A new pivot low reaches fibbot3.
- Low crosses above the prior bar’s low.
- A green point is drawn beneath the bar.
- Confirmation via a horizontal segment at the pivot level.
Note on false signals:
In choppy markets, there can be whipsaws. Consider filtering signals with volume, candlestick patterns or market structure to improve reliability.
Band Extension
The extend parameter projects all six bands into the future. It calculates a slope based on the SMMA change over extend/10 bars and draws forward segments at:
- 0 % (the SMMA itself)
- 38.20 % (fibtop1/fibbot1)
- 61.80 % (fibtop2/fibbot2)
- 100.00 % (fibtop3/fibbot3)
This forward projection highlights where dynamic support/resistance levels may lie over the next n periods.
Indicator Settings
| Parameter | Default | Description | Recommended Range |
|---|---|---|---|
period |
20 | SMMA period & slope base | 10 – 50 |
width |
1 | Overall multiplier for Fibonacci bands | 0.5 – 2 |
fibratio1 |
1.618 | Ratio for Band 1 (38.2 %) | 1.0 – 2.0 |
fibratio2 |
2.618 | Ratio for Band 2 (61.8 %) | 2.0 – 3.5 |
fibratio3 |
4.236 | Ratio for Band 3 (100 %) | 3.5 – 5.0 |
extend |
30 | Bars to project bands forward | 10 – 100 |
length1 |
100 | Initial ATR smoothing length | 50 – 200 |
Tip: On higher timeframes increase period and length1 for smoother bands; on lower-volatility instruments reduce width to avoid excessive band width.

Conclusions & Best Practices
- Strengths: Dynamically combines volatility and Fibonacci ratios to map out clear support/resistance zones in both trends and ranges.
- Complementary filters: Improve signal quality by layering volume analysis, momentum divergences (e.g. RSI/MACD) or static S/R levels.

Ivan, it looks as if something is really wrong with this indicator. When I import and apply it (as is), it produces results very different from what you show. There is a very significant (and unrealistic) narrowing of the bandwidth from barindex-200 onwards.
