Mastering Position Sizing: When and How to Increase Trading Volume for Maximum Profits
Introduction: The Critical Decision of Adding to Positions
Increasing trading volume is one of the most critical yet misunderstood decisions in active trading. When a trade starts moving in your favor after initial hesitation, many traders face the temptation to add to their position—but is this strategic or reckless? This guide reveals when increasing trading volume works, when it backfires, and how professionals scale positions without amplifying risk

In trading, one of the most challenging decisions is determining whether to increase position size after initial entry. Many traders face this dilemma:
"The market moved against me, then reversed—should I add more volume now that my analysis seems confirmed?"
The answer is nuanced. While adding to winning positions can amplify profits, doing so at the wrong time can turn a disciplined strategy into reckless gambling. This guide explores:
- When increasing volume is justified
- The psychological pitfalls of late position sizing
- How professional traders scale in without increasing risk
- Risk management techniques for sustainable growth
By the end, you'll understand how to strategically adjust positions while maintaining emotional control and risk discipline.
The Problem with Adding Volume After Initial Entry
Why Traders Are Tempted to Increase Position Size Late
After entering a trade, traders often want to "double down" when:
- Price initially moves against them, then reverses
- A pullback forms what appears to be a higher low (in uptrends) or lower high (in downtrends)
- The market seems to "confirm" their original thesis
However, this approach carries hidden risks.
The Three Fatal Flaws of Late Position Sizing
- Risk Concentration
- Your initial position already accounted for a specific risk percentage (e.g., 1% of capital).
- Adding more volume later disrupts this balance, potentially overexposing your account.
- Confirmation Bias
- A temporary reversal doesn’t guarantee trend continuation.
- Markets often fake out traders with false breakouts/reversals.
- Emotional Trading
- The urge to "make up for losses" or "prove you were right" leads to impulsive decisions.
Key Insight: If you wanted a larger position, you should have taken it at the initial entry—not after emotional stress from drawdown.
The Exception—When Adding Volume Works
A new trader entering after the pullback (e.g., at "Point 2") operates under different conditions:
- The initial risk event (drawdown) already occurred.
- Statistical probability of another adverse move decreases.
- Their entry has a tighter stop-loss, improving risk-reward.
Example:
- Trader A enters at 100(Point1),suffersadropto100(Point1),suffersadropto90, then price recovers to $95.
- Trader B enters at 95(Point2),withastopat95(Point2),withastopat93.
- Trader B’s risk is objectively lower—they can justify a larger position.
How Professionals Scale In Safely
Instead of adding volume impulsively, experienced traders:
- Wait for structural confirmation (e.g., a "step pattern" forming).
- Secure partial profits first (e.g., close 30-50% of the initial position).
- Adjust stops to breakeven or better before adding.
This method locks in gains while allowing controlled position growth.
The Psychology of Position Sizing
The Emotional Rollercoaster of Early Entries
If you entered at Point 1, you likely experienced:
- Anxiety as price moved against you.
- Relief when it reversed.
- Temptation to "prove yourself right" by adding volume.
This mindset is dangerous. Trading should be mechanical—not an ego-driven battle.
Why Late Volume Increases Feel Like Gambling
- You’re no longer following a plan—you’re chasing validation.
- Each addition increases emotional attachment to the trade.
- Losses hurt more because they’re now "personal."
Solution: Stick to predefined rules. If your strategy didn’t allow adding volume initially, don’t improvise mid-trade.
Risk Management—The Foundation of Smart Volume Increases
The Golden Rules of Position Sizing
- Never Risk More Than Planned
- If your strategy allows 2% risk per trade, adding volume shouldn’t exceed this.
- Adjust Position Size Based on Stop-Loss Distance
- Tighter stops allow larger positions (and vice versa).
- Use "Market Money" for Scaling
- Once partial profits are secured, reuse them—not fresh capital.
Example of Disciplined Volume Growth
- Enter with 5 lots, risking 1% of capital.
- Price moves favorably; close 2 lots at +2R profit.
- Move stop to breakeven on remaining 3 lots.
- Add 2 more lots on a confirmed continuation pattern.
- Result: Larger position, but same (or lower) initial risk.
Building Long-Term Success
Two Pillars of Consistent Trading
- A Clear Strategy
- Price action, trend following, or algorithmic systems.
- Mentorship & Continuous Learning
- Avoid costly mistakes by learning from experts.
Final Wisdom: Control What You Can
- You can’t control markets, but you can control:
- Position size
- Risk per trade
- Emotional discipline
Remember: Trading without rules isn’t investing—it’s gambling. The difference between success and failure often comes down to patience and position sizing discipline
Conclusion: The Smart Path to Growing Your Account
- Do NOT add volume impulsively after drawdowns.
- DO scale in strategically with secured profits.
- ALWAYS prioritize risk management over ego.
By following these principles, you can grow your account sustainably—reaching the stage where you’re trading with "house money" rather than risking hard-earned capital.
