Bollinger Band Trading

Standard settings are: 20-period SMA for middle band, 2 standard deviations for bands. These defaults work well for most timeframes and instruments. Variations: shorter period (10) for more signals but more noise. Longer period (50) for smoother, fewer signals. 2.5 SD for wider bands (fewer touches). Start with standard 20,2 settings and adjust based on your experience. Most traders stick with defaults because that's what the majority uses, creating self-fulfilling behavior at those levels.

Squeeze identification: 1) Visual: bands should look almost parallel and significantly narrower than recent history. 2) Band Width: compare to the last 50-100 periods. If the current width is in the lowest 20%, it's a squeeze. 3) Keltner: if the BB bands are inside the Keltner Channels, that's a confirmed squeeze. As a rough guide: for the A50, normalized band width below ~0.5% (roughly 60-90 points at current levels); for the Nikkei 225, below ~0.5% (roughly 180-260 points). Because SGX contracts sit at very different index levels, compare normalized band width (or its percentile) to recent history rather than relying on absolute point counts.

No, be selective. Trade squeezes that have: 1) Adequate duration (5+ periods minimum). 2) Tight compression (Band Width in low percentile). 3) Volume confirmation on breakout. 4) Alignment with higher timeframe trend (preferred). 5) Clear band close (not just wick). Skip squeezes that: lack volume, break against major trend, are very short duration, or occur right before major events (unpredictable). Quality over quantity - one good squeeze trade beats three mediocre ones.

False breakouts happen - it's part of the strategy. If stopped out: 1) Accept the loss (you had a stop for this reason). 2) Don't immediately re-enter in opposite direction. 3) Wait for bands to re-squeeze or another clear signal. 4) Review: was volume weak? Did you chase instead of waiting for close? 5) Track your false breakout rate - should be under 40% for profitable system. Protection: use filters (volume, Keltner confirmation), wait for candle close not intraday break, size appropriately so single loss doesn't hurt.

Duration depends on squeeze timeframe: Intraday squeeze (15-min/hourly): trades last hours to 1 day. Daily squeeze: trades last 2-7 days typically. Weekly squeeze: trades can last 2-4 weeks. The general rule: expect the explosive move to last roughly as long as the squeeze lasted. A 10-day squeeze might produce a 5-10 day trending move. Exit when: price stops walking the band, closes beyond middle band against you, or reaches your target. Don't have fixed time exit - let the band walk continue until it ends.

Keltner Channel setup: 1) Add Keltner Channels to chart (most platforms have this). 2) Settings: 20-period EMA, 1.5 ATR for bands (standard). 3) Also add Bollinger Bands (20, 2). 4) Squeeze confirmed when BB upper band is BELOW KC upper band AND BB lower band is ABOVE KC lower band. 5) Visually: BB 'inside' KC. 6) Many platforms have 'TTM Squeeze' indicator that shows this automatically with dots (red = squeeze, green = no squeeze). This double confirmation produces higher quality signals than BB alone.

Band walk trading: 1) After confirmed breakout, expect price to 'walk' the band. 2) Stay in trade as long as price touches outer band each period. 3) Don't exit just because price touched the band - that's expected in trends. 4) Trail stop using middle band (exit if close beyond it). 5) Add to position on pullbacks to middle band that hold. 6) Exit when: price fails to touch band for 2-3 consecutive periods, closes beyond middle band, or bands start contracting significantly. 7) Band walks can last many periods - be patient. The explosive move from squeeze often becomes a trending band walk.

Timeframe selection depends on your style: Intraday (15-min to hourly): more frequent squeezes, smaller moves, requires active monitoring. Best for day traders with time to watch. Daily: good balance of frequency and move size. Squeezes last 1-3 weeks, breakouts for days. Best for swing traders. Weekly: fewer squeezes but larger moves. Trades last weeks to months. Best for position traders. Recommendation: start with daily timeframe. It filters noise while providing meaningful opportunities. Use hourly for entry timing within daily squeeze. Multi-timeframe: daily squeeze confirmed, enter on hourly breakout for precise timing.

Squeeze quality scoring: 1) Duration: 5-8 periods (1 point), 8-15 periods (2 points), 15+ periods (3 points). 2) Tightness: Band Width 20-30th percentile (1 point), 10-20th percentile (2 points), below 10th (3 points). 3) Keltner confirmation: yes (2 points), no (0 points). 4) Higher TF alignment: yes (1 point), no (0 points). Total: 0-9 points. Sizing: 0-3 points = skip or 50% size. 4-6 points = standard size. 7-9 points = 150% size (high quality). This systematic approach removes emotion and ensures best setups get most capital.

Multiple squeeze management: 1) Prioritize by quality score (trade the best first). 2) Check correlation - correlated instruments count as a single bet. 3) Allocate capital: don't exceed 2-3% risk per squeeze trade, max 8-10% aggregate. 4) Stagger entries: if 3 squeezes, take the best first, wait for the breakout before committing to others. 5) Track aggregate direction: if all break the same way, you have a concentrated directional bet. Example: A50, Nikkei 225 and FTSE Taiwan all in a squeeze. A50 quality 8, Nikkei 6, FTSE Taiwan 5. Trade the A50 with larger size, Nikkei medium, FTSE Taiwan small or skip. Monitor total exposure.

System components: 1) Data feed: real-time or EOD price data. 2) Band calculation: compute BB and KC in code. 3) Squeeze detection: Band Width percentile calculation, KC overlap check. 4) Alert generation: notify when squeeze forms, when breakout occurs. 5) Signal generation: direction, entry, stop, target calculation. 6) Screening: scan multiple instruments simultaneously. Implementation: Python with pandas for calculations, alerts via email/SMS/Telegram. Backtest: validate squeeze detection accuracy and breakout success rate. Key metrics: squeeze detection lead time, false squeeze rate, breakout capture rate. Start simple (Band Width percentile only) and add complexity (Keltner, ML direction) as system proves reliable.

Statistical basis: 1) Volatility clustering: high volatility follows low volatility (empirically proven). 2) Mean reversion of volatility: extreme low volatility (squeeze) reverts to mean (expansion). 3) Trend persistence: once direction established, tends to continue. Quantifying edge: backtest shows squeeze breakouts have higher trend persistence than random entries. Win rate typically 50-60% but winners (during expansion) larger than losers (false breakouts). Profit factor 1.3-1.8 typical. Edge degrades in high VIX (already elevated volatility reduces squeeze frequency). Edge calculation: Expected Value = (Win% × Avg Win) - (Loss% × Avg Loss). Positive EV = edge exists.

Institutional approach: 1) Volatility surface analysis: compare implied vs realized volatility. Squeeze = IV above RV (options expensive relative to actual moves). 2) Options premium selling: sell straddles/strangles during squeeze if expecting continuation. Collect premium. 3) Gamma scalping: buy options during squeeze (cheap IV), delta hedge, profit from expansion. 4) Cross-asset: apply squeeze analysis across stocks, commodities, currencies for diversification. 5) Systematic: rules-based detection and execution, not discretionary. 6) Size management: large enough to matter, small enough to exit. 7) Risk budgeting: squeeze strategies allocated specific risk budget within broader portfolio. Retail adaptation: focus on options long (defined risk), systematic detection, and proper sizing.

IV-squeeze relationship: 1) During squeeze: realized volatility very low, but IV may not drop equally (stays above RV). Creates IV premium. 2) Options implication: options 'expensive' relative to actual movement during squeeze. 3) Strategy adaptation: buying options during squeeze can be costly due to IV premium. Consider: selling options (premium collection) if you expect squeeze to continue, or buying with expectation that RV expansion will exceed IV's current pricing. 4) IV crush: after breakout, if RV spikes above IV, options appreciate. If IV was already pricing breakout, less options gain. 5) Practical: for directional squeeze breakouts, futures may be cleaner than options. Use options when IV is genuinely low (below 20th percentile) or for defined-risk entries.

Failure modes and mitigation: 1) Extended squeeze: squeeze continues longer than expected. Mitigation: don't enter until breakout, accept waiting. 2) Failed breakout: breaks out then reverses. Mitigation: volume confirmation, Keltner validation, higher TF alignment. 3) Opposite direction: you have bias but it breaks other way. Mitigation: don't predict direction, trade the break. 4) Regime change: squeeze strategy stops working. Mitigation: track performance, reduce size during drawdown, have backup strategies. 5) Over-trading: seeing squeezes everywhere. Mitigation: strict criteria, quality scoring. 6) Correlation blow-up: multiple squeeze trades all fail together. Mitigation: cap aggregate exposure, diversify uncorrelated. Systematic tracking of failures helps refine the strategy over time.
