Aluminium Trend Follower

Aluminium has lower volatility compared to other base metals like Nickel or Copper. This means trends develop more gradually and are easier to identify and follow. Daily moves of 0.5-1.5% are typical versus 2-3% for more volatile metals. This steadier price action gives beginners more time to react and make decisions, making it an excellent training ground for trend following principles.

Trend following accepts many small losses (false signals and whipsaws) in exchange for occasional large wins (extended trends). A system might win only 40-45% of trades, but winners average 2-3x larger than losers. For example, 10 trades with 4 winners averaging $250 and 6 losers averaging $100: Profit = (4 x 250) - (6 x 100) = $1,000 - $600 = $400 profit despite 40% win rate.

CME Aluminum (ALI) is 25 metric tonnes, physically delivered, with a large notional value (tens of thousands of dollars), suited to larger accounts. For beginners and smaller accounts, the LME aluminium mini (5 metric tonnes, cash-settled) requires less margin and allows better position sizing. Both track the same aluminium price - you're just trading different quantities. Note that CME lists no aluminum mini, so the mini is accessed via the LME through U.S. brokers. Start with the mini to learn trend following dynamics before considering the larger contract.

For intraday trading, use 15-minute charts with reference to hourly and daily for trend direction. For positional trades (holding days to weeks), use daily charts with reference to weekly. Always check higher timeframes to ensure your trade direction aligns with the larger trend. Never fight the higher timeframe trend.

China produces approximately 60% of global aluminium supply. Chinese production data, environmental policies (which affect smelter operations), domestic demand, and export policies significantly impact global prices. Any news about China's aluminium industry can move global LME and CME prices. Traders should monitor China PMI data and any aluminium-specific news from China.

Key differences: Pullback - occurs on declining volume, stays above key support (50 EMA, recent swing low), ADX remains above 20, higher timeframe trend intact. Reversal - occurs on increasing volume, breaks below key support, ADX drops below 20 or shows divergence, higher timeframe trend structure breaks. If in doubt, wait for clarity rather than forcing a trade. Use multiple timeframes - a pullback on 15-min within a daily uptrend is likely to resolve higher.

Aluminium can gap based on overnight LME moves. For positions held across sessions: (1) Reduce position size to 50-75% of intraday size, (2) Ensure stop is wide enough to survive typical overnight gaps (1-1.5%), (3) Check LME trend, (4) Avoid holding through major China data releases or LME inventory reports, (5) Use overnight (positional) margin, not intraday. If your system is strictly intraday, close positions before the CME Globex daily break (~5:15 PM ET).

London/LME hours (the global benchmark's core session, roughly 3 AM - 12 PM ET) are best for trend trades. This is when global price discovery occurs with highest volume. The U.S. afternoon (after the LME winds down) can have valid signals but lower conviction. Avoid the first 15 minutes after a session open (noise) and the last 30 minutes (position squaring). If a trend signal appears outside core LME hours, consider waiting for the London session to confirm before taking a full position.

Volume filters: (1) Entry signal should have volume at least equal to 20-period average, (2) Trend advances should show expanding volume, (3) Pullbacks should have declining volume (healthy), (4) Skip signals occurring on significantly below-average volume (<70% of average), (5) Volume divergence (price advancing on declining volume) warns of potential reversal - tighten stops or take partial profits. Compare to same-session averages since London/LME-hours volume is naturally higher.

Very important. CME Aluminum tracks LME Aluminium (the global benchmark), and CME ALI settles tied to the LME window - trading against LME direction has a low success rate. Best practice: (1) During London/LME hours, require LME trend alignment for a full position, (2) CME ALI signals during thin U.S. hours without LME confirmation should be half-size, (3) If CME ALI and LME trends diverge, favor the LME direction, (4) Watch LME key levels and inventory for reference. Aligned trades have significantly higher success rate.

Components: (1) Regime identification - categorize market as Strong Trend (ADX>30), Weak Trend (ADX 20-30), Ranging (ADX<20), Vol Expansion (ATR rising), Vol Contraction (ATR falling). (2) Parameter mapping - assign EMA periods, ADX thresholds, position size, and profit targets to each regime. (3) Switching rules - update regime classification daily for positional, each session for intraday. (4) Backtest the complete adaptive system vs fixed parameters over 3+ years. (5) Walk-forward validate to ensure robustness. The adaptive approach typically improves risk-adjusted returns 20-40% over fixed systems.

Recommended approach: Initial entry 50% at signal, add 25% at 1x ATR with ADX confirmation, add final 25% at 2x ATR with new swing high/low. Stop management: move to entry after first add, trail at 2x ATR after second add. Exit scaling: 25% at 3x ATR, 25% at 4x ATR, trail 50% until reversal. Key rules: never add to losers, each add must have higher/lower price (pyramiding up, not averaging down), reduce adds if ADX starts declining, skip adds if volume divergence appears.

Divergence framework: (1) ADX divergence - price new high but ADX lower than previous, (2) Momentum divergence - RSI/MACD not confirming price, (3) Volume divergence - price advancing on declining volume, (4) Breadth divergence - Aluminium trend not confirmed by other base metals. Action levels: Single divergence - tighten stops. Two divergences - take 30-50% profit. Three divergences - take 70%+ profit, no new entries. Divergence doesn't mean immediate reversal but signals reduced risk-reward for trend continuation.

China event protocol: (1) Identify high-impact events: China PMI, aluminium production data, environmental policy announcements, trade policy changes. (2) Before event: reduce position to 50%, widen stops or use guaranteed stops if available. (3) During event: avoid new entries, let existing positions work with widened parameters. (4) After event: wait 30-60 minutes for volatility to settle before resuming normal trading. (5) If event creates trend change, be quick to reverse - China news can establish new multi-week trends. Major events override technical signals temporarily.

Key metrics: (1) Profit factor by regime - is system profitable in all regimes or only trending markets? (2) Average hold time for winners vs losers - winners should be held longer. (3) MAE/MFE analysis - Maximum Adverse/Favorable Excursion shows if stops are too tight/wide. (4) Win rate by entry type (breakout vs pullback) - optimize entry approach. (5) Performance by session - compare U.S. vs London/LME session results. (6) Correlation with LME - measure how much alignment improves results. (7) Slippage analysis - actual vs theoretical fills. Review monthly, adjust parameters quarterly if needed.
