Trend-following as one testable signal procedure

How the procedure starts

The procedure begins by selecting a portfolio of markets to watch and then waits for an upward or downward move before opening an initial long or short position.

Market selection is described as intentional rather than random, with the objective of participating in markets that exhibit trends.

Rules specified before entry

The approach is characterized as systematic: entry, exit, and position size are specified before a trade is opened, using if-then contingencies rather than discretionary bets made while watching the screen.

An exit for either a gain or a loss is specified before entry, and that pre-commitment is contrasted with directional commentary that never states when a view should be abandoned.

Join a market that is already moving

The reason a market is moving is treated as unnecessary. The stated priority is to join a market that is already moving and to know in advance where and when to exit if price turns against the position.

Trend-following is a rules-based way to take long or short exposure after price is already moving and to stay with that exposure until a predefined adverse turn.

Breakout-entry and predefined-exit

A representative long entry is a late breakout after momentum is already visible. That breakout-entry waits for visible momentum instead of trying to locate the exact start of a move.

A representative exit comes after the move has turned, so the operator is not aiming to catch the exact low or high. The predefined-exit is the loss or reversal condition that is known before a position is opened.

Planned-loss-point

The downside is treated as a quantity set before entry, while the upside is treated as unknown, and losses are accepted as a planned part of the process.

The planned-loss-point is the known downside at which the procedure exits, independent of unknown upside.

Price-only-input and reaction-versus-prediction

Market identity and a fundamental explanation are treated as optional. Price data alone is said to be enough to decide whether a series can be traded. Price-only-input treats the price series as sufficient market-state input, without requiring a causal story or even the market's name.

Devices such as breakouts or moving averages are framed as reaction tools, not as a stack of predictors. The stated limit is that the procedure can respond but cannot forecast. Reaction-versus-prediction means acting after the market has moved, rather than stacking technical devices in an attempt to forecast the next move.

Intentional-abstention and holding-period

Some operators remain out of the market for stretches of time. Intentional-abstention is staying out of a market that is not presenting a qualifying trend, rather than forcing activity.

Longer-horizon operators are distinguished from shorter-horizon systematic traders, but both are described as applying historically inspected rules without discretion. The holding-period is the time a position remains open under the system's exit rules. The operators discussed here are described as longer-horizon.

What must be specified

Editorial: the archive describes a historical workflow. TradersWeek uses that workflow to teach a single point. A signal is the procedure's output: enter, exit, or abstain, produced from rule inputs, market state, and execution constraints rather than from a forecast.

Editorial: if entry, exit, size, or abstention is left for later judgment, the thing being tested is no longer the systematic-procedure.
