The Bollinger Bands Fast Trend Indicator [DCD], created by DutchCryptoDad, is a powerful technical analysis tool designed for traders seeking enhanced precision in trend detection and trade signal generation. Built as an evolution of the classic Bollinger Bands, this indicator introduces customizable parameters and advanced moving average integration to deliver clearer, more responsive signals across volatile and ranging markets.
Whether you're analyzing cryptocurrencies, forex, or stock charts, this script enhances decision-making by combining dynamic volatility bands with multi-layered trend confirmation systems. Below, we explore its functionality, setup process, and practical applications—optimized for clarity, performance, and real-world trading use.
How the Bollinger Bands Fast Trend Indicator Works
At its core, the indicator calculates two distinct Bollinger Bands: a short-term band for rapid responsiveness and a long-term band for trend context. Unlike traditional implementations that rely on fixed settings, this version allows independent configuration of standard deviations and period lengths for each band.
The key innovation lies in the BBTrend value, derived from normalizing the difference between upper and lower bands against the short middle band. This normalized metric provides a smoothed oscillator-like reading that reflects both volatility and directional momentum.

This BBTrend value is then smoothed using a user-selected moving average—offering flexibility across five types: Simple (SMA), Exponential (EMA), Least Squares (LSMA), Hull (HMA), and Weighted (WMA). The result is a dual-line system where crossovers and crossdowns generate actionable trading cues.
Key Features That Set It Apart
Customizable Dual Bollinger Bands
Each Bollinger Band operates independently:
- Short BB Length (default: 10): Ideal for capturing immediate price movements.
- Long BB Length (default: 50): Offers broader market context.
Separate Standard Deviation Multipliers:
- Short: default 1.0
- Long: default 2.0
This differentiation enables tighter bands during consolidation and wider ones during high volatility, improving accuracy in dynamic environments.
Multiple Moving Average Options
Traders can select the most suitable smoothing method based on their strategy:
- SMA: Best for long-term trend confirmation
- EMA: Reacts faster to recent price changes
- HMA / LSMA: Minimizes lag for swing and intraday traders
- WMA: Emphasizes recent data points
This adaptability ensures compatibility with various trading styles—from scalping to position trading.
Visual Signal Detection System
The indicator employs intuitive visual markers:
- Green Circles: Indicate crossover points (BBTrend crosses above MA) — potential buy signals
- Red Circles: Signal crossdown events (BBTrend falls below MA) — potential sell signals
Additionally, a color-coded histogram displays trend strength:
- Green bars: Bullish momentum
- Red bars: Bearish momentum
Bar intensity increases with trend strength, allowing quick assessment of market pressure.
Setting Up the Indicator on TradingView
Step-by-Step Installation Guide
- Open your preferred chart on TradingView.
- Click “Indicators” at the top of the chart.
- Search for “Bollinger Bands Fast Trend Detector” or “DCD”.
- Select the script by DutchCryptoDad and apply it to the chart.
Once applied, the default settings will activate immediately. You can begin observing the dual Bollinger Bands, moving average line, and histogram without further configuration.
Adjusting Parameters for Optimal Performance
Customization is critical for aligning the tool with your trading timeframe and asset class:
| Parameter | Default Value | Purpose |
|---|---|---|
shortLengthInput | 10 | Controls sensitivity of short-term band |
longLengthInput | 50 | Defines baseline trend duration |
shortDevMultInput | 1.0 | Adjusts width of short band |
longDevMultInput | 2.0 | Sets volatility range for long band |
maTypeInput | SMA | Choose smoothing method |
maLengthInput | 14 | Determines MA responsiveness |
For day traders, consider reducing the MA length to 9 and using HMA for faster reactions. Swing traders may prefer EMA(21) with higher deviation multipliers to filter noise.

Interpreting Signals Like a Pro
Identifying High-Probability Entries
Look for confluence between:
- A green circle (crossover)
- A rising green histogram
- Price near or bouncing from the short Bollinger Band lower level
This combination suggests strong bullish momentum building after a pullback—ideal for long entries.
Conversely, a red circle coinciding with darkening red histogram bars and price approaching the upper band often precedes reversals.
Avoiding False Signals
No indicator is perfect. To reduce whipsaws:
- Use in conjunction with volume analysis
- Confirm signals with support/resistance levels
- Apply on higher timeframes (H1 and above) for greater reliability
Avoid trading signals during low-volatility periods or sideways markets unless there’s clear breakout potential.
Frequently Asked Questions (FAQ)
Q: Can this indicator be used for crypto trading?
A: Absolutely. Its sensitivity to volatility makes it especially effective for cryptocurrencies like Bitcoin and Ethereum, which exhibit strong trending behavior.
Q: Is the script free to use?
A: Yes. As an open-source Pine Script on TradingView, it's freely accessible to all users. However, redistribution must comply with TradingView’s House Rules.
Q: Does it repaint or lag significantly?
A: No repaint occurs—the signals are calculated in real-time based on completed candles. While all indicators have some inherent lag, the use of fast MAs like HMA minimizes delay.
Q: What timeframes work best with this tool?
A: It performs well across M15 to D1 charts. For scalping, pair it with HMA(9); for swing trading, combine with SMA(20) or longer.
Q: How does it differ from standard Bollinger Bands?
A: Traditional BB only shows volatility ranges. This version adds trend direction, momentum strength via histogram, and precise entry triggers through MA crossovers—making it far more actionable.
Q: Can I automate trades using this indicator?
A: While the script itself doesn’t include alerts or auto-execution, you can set up custom alerts on TradingView when crossovers occur, enabling semi-automated strategies.
