What is trend following?

Time-series momentum (TSMOM), explained without the jargon.

Trend following is one of the oldest and most-studied systematic strategies. The idea is simple: when a market has been going up, lean long; when it has been going down, lean short; and size the position by how much the market moves, not how strongly you feel about it. It makes no attempt to predict tops or bottoms — it rides established moves and cuts the ones that fade.

Time-series momentum vs. cross-sectional momentum

The specific form most trend-followers use is time-series momentum, often shortened to TSMOM. It looks at each instrument’s own recent return — say, the last few months — and takes a position in the direction of that trend. That is different from cross-sectional momentum, which ranks instruments against each other and buys the winners while shorting the losers. TSMOM asks “is this market trending up or down on its own terms?” rather than “which markets are strongest relative to the rest?”

Why it tends to work across markets

Trends recur because of how information spreads and how people react to it: news is absorbed gradually, investors chase moves, and risk is transferred over time rather than instantly. Because that behaviour is not specific to one market, time-series momentum has historically shown up across equity indices, bonds, commodities, and currencies — which is exactly why trend-followers diversify across many liquid futures rather than betting on one. Diversification is doing a lot of the work: no single market has to cooperate for the strategy to function.

Volatility targeting: the risk dial

A good trend-following system does not just decide direction — it decides size. The common approach is volatility targeting: measure each market’s recent realised volatility and take a smaller position in a wild market and a larger one in a calm market, so that each position contributes a similar amount of risk. This keeps the portfolio’s overall risk roughly steady instead of ballooning when markets get turbulent. It is the difference between a strategy that lurches and one that participates steadily.

The honest drawbacks

Trend following is not free money. Its well-known weakness is choppy, sideways markets: when prices oscillate without committing to a direction, the strategy gets whipsawed — entering on a move that promptly reverses — and bleeds small losses while it waits for a real trend. Trend-followers accept many small losing trades in exchange for a few large winners, which means stretches of flat-to-negative performance are normal and expected, not a sign something is broken. It requires patience and, above all, sticking to the system through the dull periods.

How Oraculum Bots uses it

Oraculum Bots runs a volatility-targeted time-series momentum strategy across liquid futures inside your own Interactive Brokers account. It sizes from realised volatility, caps gross exposure at the leverage you choose, and can be validated on paper with live data before you commit a dollar. It is built for steady, risk-adjusted participation — not outsized bets, and with no promise of a particular return.
