Trailing Stop

Intermediate
Trading ConceptsAlso known as: trailing stop-loss, dynamic stop

A dynamic stop-loss order that automatically adjusts in the direction of a profitable trade, maintaining a set distance from the highest price reached. Trailing stops lock in profits as the trade moves favorably while still allowing room for normal price fluctuations.

Why It Matters

  • 1Trailing stops help prop traders protect profits without setting arbitrary take-profit levels.
  • 2In trending markets, a trailing stop lets winners run while guaranteeing a minimum profit once the trade moves in your favor.
  • 3This is especially valuable in prop firm evaluations where you need to build profits steadily toward the target.
  • 4A well-placed trailing stop can capture large trending moves that a fixed take-profit would have exited too early, while ensuring you don't give back all gains if the trend reverses.

Example

  1. 1You enter long ES at 4,500 with a 10-point trailing stop.
  2. 2Initially, your stop is at 4,490. The market rallies to 4,520 — your trailing stop moves up to 4,510, locking in at least 10 points of profit.
  3. 3The market continues to 4,535 (stop now at 4,525), then reverses.
  4. 4You're stopped out at 4,525 for a 25-point ($1,250/contract) profit.
  5. 5Without the trailing stop, a fixed take-profit — for example, a 15-point target at 4,515 — would have captured only $750 per contract, missing the additional $500 in profit the trailing stop captured.

Common Mistakes

  • Setting the trailing distance too tight, causing premature stop-outs on normal retracements
  • Not adjusting the trailing distance based on the instrument's typical volatility
  • Using trailing stops in choppy, range-bound markets where they get triggered by noise
