Bollinger Band Strategies

Strategy 1: Band Bounce (Mean Reversion)

Concept: Price tends to return to middle band (mean).

Long Setup:

1. Price touches or pierces lower band
2. Wait for bullish candlestick pattern
3. Entry on confirmation
4. SL below the low
5. TP at middle band or upper band

Short Setup:

1. Price touches or pierces upper band
2. Wait for bearish candlestick pattern
3. Entry on confirmation
4. SL above the high
5. TP at middle band or lower band

Best conditions: Ranging/sideways market

Example:

FCPO touches lower band at 4,180
Hammer candle forms
Entry: 4,185
SL: 4,170
TP: 4,220 (middle band)

Strategy 2: Bollinger Squeeze

Concept: Low volatility (squeeze) often precedes big moves.

Identifying Squeeze:

• Bands contract significantly
• Band width at multi-period low
• Price consolidating in tight range

Trading Squeeze:

1. Identify squeeze (narrow bands)
2. Wait for breakout of the squeeze
3. Entry in direction of breakout
4. SL inside the squeeze range
5. TP based on measured move or next S/R

Example:

Bands squeeze (narrowest in 20 periods)
Price breaks above upper band with volume
Entry: On breakout candle close
SL: Middle band
TP: Measured move or resistance

Strategy 3: Walking The Bands

Concept: In strong trends, price "walks" along upper or lower band.

Uptrend Walk:

• Price stays near upper band
• Pullbacks to middle band are buying opportunities
• Don't short just because price is at upper band!

Downtrend Walk:

• Price stays near lower band
• Rallies to middle band are selling opportunities
• Don't buy just because price is at lower band!

How to trade:

1. Identify trending market (walking the bands)
2. Wait for pullback to middle band
3. Entry in trend direction
4. SL beyond middle band
5. TP at band or trailing stop

Strategy 4: Double Bottom/Top at Bands

Bullish Double Bottom:

1. Price touches lower band, bounces
2. Price returns to lower band area (but higher low)
3. Second touch shows less momentum
4. Entry on bounce from second touch
5. Strong reversal signal

Bearish Double Top:

1. Price touches upper band, reverses
2. Price returns to upper band area (but lower high)
3. Second touch shows less momentum
4. Entry on rejection from second touch
5. Strong reversal signal

Common Bollinger Band Mistakes

Mistake 1: Trading Bands Blindly

Wrong: Price touches lower band → Buy immediately

Right: Price touches lower band → Wait for confirmation candle → Then buy

Mistake 2: Counter-Trend in Strong Trends

Wrong: Price at upper band in uptrend → Short

Right: In uptrend, price walking upper band → Look for pullback to middle band to go long

Mistake 3: Ignoring Squeeze Duration

Wrong: Assume every squeeze leads to big move

Right: Longer squeeze often means bigger breakout. Short squeezes may fizzle.

Mistake 4: Using Wrong Settings

Wrong: Use 10-period BB on daily chart

Right: Stick to 20,2 standard settings unless you have specific reason to change.

Soalan Lazim (FAQ)

Q: "Setting apa terbaik untuk FCPO?"

A: Standard 20, 2 works well. No need to change unless you have specific reason.

Q: "Boleh trade BB alone?"

A: Better with confirmation (RSI, candlesticks, S/R). BB alone can give false signals.

Q: "Price always at upper band, should I short?"

A: Not necessarily! Could be "walking the bands" in strong uptrend. Check trend first.

Q: "How long does a squeeze last?"

A: Varies. Short squeezes (few days) to long squeezes (weeks). Longer squeeze = potentially bigger breakout.
