Aluminum Trend Follower

Aluminum has lower volatility compared to other base metals like Nickel or Copper. 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 decide, making it a good training ground for trend following principles. Just remember that the COMEX ALI book is thinner than the largest metals markets, so fills can be less smooth.

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 US$1,200 and 6 losers averaging US$500: profit = (4 × 1,200) - (6 × 500) = US$4,800 - US$3,000 = US$1,800 despite a 40% win rate.

There is no mini aluminum contract on COMEX — only the 25 MT ALI, with roughly US$72,000 notional near US$2,900/tonne. To respect a 2% risk rule on a typical stop you generally need a five-figure-plus account to trade even one contract, so ALI is better suited to well-capitalized traders. Smaller accounts that want aluminum exposure for learning sometimes use aluminum-producer equities or broad metals ETFs instead, but those are different instruments with different behavior and are not a substitute for the futures strategy taught here. Trade the simulator first.

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 aluminum supply. Chinese production data, environmental policies (which affect smelter operations), domestic demand, and export policies significantly impact global prices — and therefore ALI, which tracks the global benchmark. Any news about China's aluminum industry can move the market. Monitor China PMI data and any aluminum-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 diverges, higher timeframe structure breaks. If in doubt, wait for clarity rather than forcing a trade. Use multiple timeframes — a pullback on the 15-min within a daily uptrend is likely to resolve higher.

ALI can gap on moves that occur while North America sleeps — especially around the London open and Asian-session data. For overnight positions: (1) reduce size to 50-75% of intraday size, (2) ensure the stop is wide enough to survive a typical overnight gap, (3) check the LME trend and inventory before you step away, (4) avoid carrying through major China data or tariff/policy announcements, (5) use overnight (initial) margin, not intraday margin. If your system is strictly intraday, square off before the 5:00 PM ET settlement.

The morning ET window (about 8:00 AM-12:00 PM ET) that overlaps the LME/London afternoon is best — this is when global price discovery occurs with the highest volume. The US afternoon (12:00-4:00 PM ET) can extend or consolidate trends. The Asian overnight has lower liquidity and more gap risk. If a signal appears overnight, consider waiting for the London overlap to confirm before taking a full position.

Volume filters: (1) the entry signal should have volume at least equal to the session average, (2) trend advances should show expanding volume, (3) pullbacks should have declining volume (healthy), (4) skip signals on significantly below-average volume (<70% of the session average), (5) volume divergence (price advancing on declining volume) warns of a potential reversal — tighten stops or take partial profits. Compare to same-session averages, since the LME-overlap window is naturally busier than the overnight.

Very important. ALI tracks LME aluminum closely — trading against the LME direction has a low success rate. Best practice: (1) during the morning ET / LME overlap, require LME trend alignment for a full position, (2) overnight ALI signals without LME confirmation should be half-size, (3) if ALI and LME briefly diverge, favor the LME direction, (4) watch the US Midwest Premium and tariff backdrop, which can move the US delivered basis even when the global trend is quiet. Aligned trades have a meaningfully higher success rate.

Components: (1) Regime identification - categorize the 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 the classification daily for positional, each session for intraday. (4) Backtest the complete adaptive system vs fixed parameters over 3+ years, including ALI's spread/slippage. (5) Walk-forward validate for robustness. An adaptive approach typically improves risk-adjusted returns versus a fixed system, but verify on your own data.

A common ladder: initial portion at the signal, add at 1x ATR with ADX confirmation, add again at 2x ATR on a new swing high/low. Stop management: move to entry after the first add, trail at 2x ATR after the second. Exit scaling: take partials into strength (e.g., 3x and 4x ATR) and trail the rest until reversal. Key rules: never add to losers, each add at a better price (pyramiding up, not averaging down), reduce adds if ADX declines or volume diverges. What's different on ALI: each contract is ~US$72,000 notional with no mini, so a three-leg pyramid implies a much larger account and three USD/CAD-exposed legs — size the full ladder to your capital before the first entry.

Divergence framework: (1) ADX divergence - price at a new high but ADX lower than the previous high, (2) Momentum divergence - RSI/MACD not confirming price, (3) Volume divergence - price advancing on declining volume, (4) Breadth divergence - aluminum's 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.

Event protocol: (1) Identify high-impact events: US Section 232 tariff changes, USMCA/cross-border developments, China PMI and production data, environmental/policy announcements. (2) Before the event: reduce size, widen stops or use resting protective orders. (3) During: avoid new entries; let existing positions work with widened parameters. (4) After: wait 30-60 minutes for volatility to settle before resuming. (5) If the event creates a trend change — a tariff shift can move the US premium and the global price together — be quick to adapt. Major events temporarily override technical signals; on thinner ALI, gaps around them can be sharp.

Key metrics: (1) Profit factor by regime - is the 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 the entry approach. (5) Performance by session - compare the LME-overlap morning vs the US afternoon. (6) Correlation with LME - measure how much alignment improves results. (7) Slippage analysis - actual vs theoretical fills, which matters more on ALI's wider spreads. Review monthly, adjust parameters quarterly if needed.
