Scaling and stop management

A position is not a single decision. Between entry and final exit there are several moments where the plan has to say something: whether to add, whether to take some off, where the stop goes as the trade moves, and how long you will give it. This lesson writes those rules. The single most important one is three words long: never widen stops.

Never widen

The stop is placed at entry, at the level the plan's STOP line specifies, at a distance that makes the position 1R. From that moment it moves in one direction only: towards price. It never moves away.

The arguments for widening are always the same. "It's just noise." "The level is a bit lower really." "If I give it a few more ticks it will work." All three may be true on the day, and the rule still holds, because the alternative is a stop that means nothing. A stop that can be widened is not a stop; it is a suggestion, and a suggestion will be overruled by the version of you that is losing.

If you find yourself widening, the journal tag is "stop widened", and Module 4 counts it. Three in a month is a plan-following problem with a specific fix: bracket orders with the stop locked, or a smaller size so the stop hurts less.

Key idea: The stop moves towards price or not at all. A stop that can be widened is a suggestion, and suggestions lose to the version of you that is losing.

Scaling in

Adding to a position is on the plan or it is not. If the plan does not have a SCALE IN line, you do not add. Averaging down, adding to a loser in the hope that a better average price rescues it, is the most reliable way to turn a 1R loss into a 3R loss, and it is prohibited by default.

Scaling into a winner can be legitimate, and it needs rules as precise as the entry:

• When: only after the initial position is at or beyond +1R.
• How much: a fixed fraction of the original size, say 50%.
• Where the stop goes: the stop on the combined position moves so that total open risk on the trade does not exceed the original 1R.
• How many times: once. A second add is a new trade with its own checklist.

Unless you have 100 or more trades on the base setup, leave the SCALE IN line as "none, v1.0". Adding is a way to increase variance, and variance is what a new plan needs least.

Scaling out

Taking part of the position off at a fixed R and letting the rest run is the most common exit structure and a reasonable default. The plan has to specify the fraction and the level:

Be aware of the arithmetic. Taking half at 2R and being stopped at breakeven on the rest yields +1R on the trade, not +2R. If your journal says "hit 2R" but the trade netted 1R, the journal is right and the feeling is wrong. Module 4 records planned R and realised R separately for exactly this reason.

Trailing rules

A trail is a mechanical rule for moving the stop towards price. It has to be written as a level, not as a feeling of "locking in profit":

• Structure trail: stop moves to one tick below each new confirmed higher low on the entry time frame.
• Moving average trail: stop moves to the close of the first bar that closes below the 10-bar EMA.
• ATR trail: stop sits at 2 × ATR(14) below the highest close since entry, recalculated each bar.
• R trail: at each new +1R milestone, stop moves up by 1R.

Pick one. Write it. Do not switch trails mid-trade because a different one would have kept you in. The one you picked is the one being measured.

Time stops

A trade that has not done what it was supposed to do within a reasonable window is a trade whose thesis is weakening even if price has not said so yet. The time stop closes it:

• Intraday: "flat if not at +1R within 30 minutes of entry".
• Swing: "close if not at +1R after 15 sessions".
• Options: "close at 21 days to expiry regardless of P&L".

The time stop and the session-end rule are the two exits traders most often forget to write, and forgetting them is how an intraday trade becomes an overnight position by accident.

Moving to breakeven

"Move to breakeven at +1R" is popular and it is not free. It converts some would-be winners into scratches every time price retests entry before continuing. Whether it is worth it depends on your setup, and the answer comes from the journal, not from how it feels. Log trades stopped at breakeven separately; after fifty trades, compare the realised R with and without the rule. Module 5 covers how to test it properly.

Try it: Write your SCALE IN, SCALE OUT, TRAIL and TIME lines. If any of them is "decide at the time", write "none" instead and put the question on the list for your first quarterly review. Then re-read your STOP line and add the words "never widened" to the end if they are not already there.

Recap

• The stop moves towards price or not at all. Widening is tagged and counted, never excused.
• Scaling in is prohibited by default. If allowed, only into winners, once, with total trade risk still capped at 1R.
• Scaling out needs fractions and levels. Half at 2R plus breakeven on the rest is +1R, not +2R.
• One trail rule, written as a level, never switched mid-trade.
• Time stops and session-end rules are the exits most often forgotten and the reason day trades become accidental overnights.
