Partial Take-Profit: How to Scale Out of Trades & Calculate Blended Exit

Why Scale Out Instead of Closing the Full Position?

Closing a trade in one shot is emotionally clean but statistically suboptimal. The market rarely delivers all its move in a single straight line. Targets that look achievable on entry often require patience through volatility, and most traders find it impossible to hold through a -5% pullback mid-trade if they are still fully exposed.

Scaling out — taking partial profits at multiple price levels — solves several real problems at once:

• Locks in gains early: You book real profit at TP1, which can never be taken away. Psychologically, being up cash transforms your mindset from anxious to patient.
• Reduces emotional pressure: A smaller remaining position is easier to hold through noise. You care less about each tick when 50% of your profit is already secured.
• Keeps a runner alive: The portion you do not close at TP1 can compound into a much larger win if the move extends to TP2 or TP3. The runner pays for your patience.
• Moves stop to breakeven: After TP1, most traders move the stop-loss on the remaining position to breakeven. Now the rest of the trade is risk-free — the worst outcome is zero, not a loss.

Three Common Scaling Approaches

There is no single correct way to split your position across TP levels. The right split depends on your conviction in the move, the market structure, and your personal risk tolerance. Three common approaches:

• 33/33/33 (even split): Close one third at each of three TP levels. Simple and balanced. Good for symmetric setups where you cannot assign higher probability to any one target.
• 50/25/25: Book half at TP1, a quarter at TP2, and a quarter as a runner. Maximizes early profit capture while still participating in larger moves. Preferred in volatile markets where TP1 is highly probable but TP2+ is uncertain.
• 50/50 (two-target): Close half at TP1, move stop to breakeven, and let the second half run to TP2 with no defined upper limit. Aggressive runner strategy best suited to trending markets with wide ranges.

The Blended Exit Price Formula

When you exit at different prices, your overall exit is the weighted average of each partial close — weighted by the size closed at each level. This is your blended exit price, and it determines your total P&L on the trade.

The formula is:

Blended Exit = (TP1_price × TP1_size + TP2_price × TP2_size + TP3_price × TP3_size + ...) / Total_closed_size

Where Total_closed_size is the sum of all partial closes. If you close 100% of the position across all TPs, total closed size equals the full position notional.

Your total P&L is then:

Total P&L = Total_closed_size × (Blended Exit − Entry) / Entry (for a long trade)

Or equivalently: P&L = sum of each partial (size × (TP_price − Entry) / Entry).

Worked Example: Three-Target Long Trade

You enter a long at $100 with a full position size of $1,000 notional. You plan three take-profit levels:

• TP1: $110 — close 50% ($500)
• TP2: $120 — close 30% ($300)
• TP3: $135 — close 20% ($200)

Step 1 — Calculate the blended exit price:

Blended = (110 × 500 + 120 × 300 + 135 × 200) / 1,000
= (55,000 + 36,000 + 27,000) / 1,000
= 118,000 / 1,000 = $118

Step 2 — Calculate total P&L:

P&L = $1,000 × (118 − 100) / 100 = $1,000 × 18% = $180

Alternatively, summing each partial:

• TP1: $500 × 10% = $50
• TP2: $300 × 20% = $60
• TP3: $200 × 35% = $70
• Total: $180

The remaining position after each close:

• After TP1: $500 remaining (50% of original)
• After TP2: $200 remaining (20% of original)
• After TP3: $0 — fully flat

Scaling Out vs Full Exit at TP1

Closing the full $1,000 at TP1 ($110) yields $100 profit — a 10% return. By scaling out to TP3, you earn $180 — an 80% improvement on the same initial setup. The cost is accepting more uncertainty: TP2 and TP3 may never be reached if price reverses.

This is the core trade-off. If your TP1 hit rate is very high but TP2+ is speculative, a heavier TP1 allocation (e.g., 60%) makes sense. If you have strong structural reasons to believe TP2 and TP3 will both be reached, a lighter TP1 (e.g., 30–40%) extracts more of the move.

The Runner Concept: Let Part of the Trade Breathe

The "runner" is the final slice of the position — the portion you refuse to close at any predefined TP. You let it run until price action gives you a clear exit signal: a trend break, a major resistance level, or a daily close against you. Runners are most powerful when the market is trending cleanly and your analysis suggests a much larger target (e.g., 5R or 10R) is possible. Without runners, consistent 1R and 2R trades are excellent, but you will never catch the occasional 10R move that defines a great month.
