What Is the Core Logic of Trend Following?
Trends persist longer than intuition expects—trend followers buy strength and hold until evidence of reversal. Systems use moving average crossovers, Donchian channel breaks, new high entries, or ATR trailing stops. Win rates are often below fifty percent; edge comes from occasional large winners covering many small losses. Trend following works across futures, FX, and equities but suffers extended drawdowns in choppy years. Diversification across uncorrelated markets or symbols smooths equity curve. It is philosophy and ruleset, not one indicator click.
Trend following accepts missing bottoms and tops—middle capture is the design.
How Do You Identify and Enter Trends?
Price above rising two-hundred-day average with fifty above two-hundred for equity bull filter. Enter on fifty-two-week high break or twenty-day Donchian upper band close. Moving average crossover systems enter golden cross with size scaled to volatility. Add on planned pullbacks to fifty-day in strong trends if rules allow pyramiding. Avoid entries when VIX spikes and index below two-hundred-day—trend odds drop. Commodity and sector trends rotate—scan multiple groups rather than one favorite stock.
Entry lag is feature—early entries in false trends increase whipsaw costs.
How Do Trend Followers Exit and Trail?
Exit on close below fifty- or hundred-day average, opposite Donchian break, or ATR multiple trail from peak. Chandelier exits hang stop below highest high minus three ATR. Partial scaling optional but full trend capture often needs letting winners run. Re-entry rules after stop-out prevent churn—wait for new high or fresh signal. Death cross on indices may reduce gross exposure across portfolio. Exits feel painful at tops because lag is inherent—accept giving back open profit for systematic discipline.
Define exit on same timeframe as entry—daily signals with intraday panic exits destroy system.
When Does Trend Following Struggle?
Range-bound years with repeated false breakouts—whipsaw bleed. Sudden regime shifts—crisis gaps through trailing stops. Single-stock concentration when one gap erases months of gains. Over-leverage magnifies drawdowns trend followers must survive psychologically. Equity curve stagnation for quarters tests commitment—many abandon before next big trend. Reduce size or pause when rolling expectancy negative across defined sample. Trend following rewards persistence through dull periods more than perfect entries.
Correlation spikes in crashes—diversification fails temporarily; gross exposure caps matter.
How Should You Size Trend Following Positions?
Volatility targeting: smaller positions in high ATR names, larger in calm trends. Risk fraction per position low because simultaneous stops may hit in crisis—one to one-and-a-half percent. Portfolio heat limit caps total open risk. Pyramiding adds only on winners at new highs with stop raised—never add to losers. Backtest maximum drawdown and size so live drawdown is survivable without abandoning rules. Trend following is marathon—position sizing determines whether you stay in the game.
Expect losing streaks of eight to twelve trades—size assuming worst streak, not average trade.
