What trade direction means

Trade direction defines how a strategy participates in the market. Every strategy can:
  • trade long only
  • trade short only
  • trade both long and short
Direction is not a preference - it is a structural decision that affects entries, exits, and risk.

Long trades

A long trade profits when price increases. Typical long logic:
  • buy strength
  • buy pullbacks
  • buy breakouts
Example:
Long trades are commonly used in:
  • bullish markets
  • trend-following systems
  • momentum strategies

Short trades

A short trade profits when price decreases. Typical short logic:
  • sell weakness
  • fade overbought conditions
  • trade breakdowns
Example:
Short trades are structurally symmetric to long trades, but behavior is often asymmetric.
Short trades usually move faster and can be riskier.

Using both directions in one strategy

A single strategy may include both long and short logic. Example:
In this case:
  • long and short entries are evaluated independently
  • each direction has its own lifecycle
  • exits may be shared or direction-specific

Shared vs direction-specific exits

Shared exits

Applies to both long and short trades.

Direction-specific exits

Direction-specific exits allow asymmetric behavior.

Direction filters

You may explicitly restrict direction: Examples:
  • long-only strategies
  • disabling shorts in bullish regimes
  • disabling longs in bearish regimes
Or conditionally:

Default behavior

If direction is:
  • explicitly stated → ATI follows it exactly
  • implied but clear → ATI may infer direction
  • ambiguous → ATI will ask for clarification

Common mistakes

Market behavior is often asymmetric. What works long may fail short.
Each direction must be fully defined to be valid.
Shorts often experience sharper moves and faster stop-outs.

Best practices

  • Start with one direction
  • Validate behavior before adding the second
  • Consider asymmetric risk rules
  • Inspect long and short trades separately
