The target percentage for taking profit: usually 50–100% of the premium. Set it before entering, not after.
What this target is
A Profit Target (Profit Target) is the planned exit price on the winning side: where you take all or part of the gain. Setting it in advance settles the hardest decision, selling while the screen is green, before greed or fear makes it for you.
Where it comes from
From structure, not wishes: the next Call Wall, the edge of the Expected Move implied by volatility, solid historical resistance, or a multiple of risk units (2R · 3R). A target with nothing measurable behind it is a nice number, not a plan.
One target or several
Scaling out is a mature middle path: half at 2R removes the risk of the trip, and the rest rides a trailing stop that chases the trend. You give up some of the best cases in exchange for a steadiness, psychological and in your books, that keeps you in the game for years.
Hypothetical example
Entry at $150 with a stop at $147: the Call Wall at $159 gives a clean 1:3. The plan: half off at $156 (2R) and the rest trailing behind the lows. Price reached $162 and then turned: the first half was taken at a profit and the second exited at $158. Nobody caught the top, and the plan paid on both halves.
Common mistake
Moving the target up each time price gets close: "it will surely keep going". A large paper profit then turns into a real loss at the reversal. Changing plans in the hour of euphoria is like changing them in the hour of panic: both are a mood dressed up as analysis.

The trading journal records each trade's target and calculates its ratio automatically, and the Gamma dashboard shows the walls that structural targets are drawn from.
