Scaling Analysis (Scale In/Out)
Analysis of whether adding to or reducing positions during a trade (scaling) is actually improving returns or just diluting your best entries.

What is Scaling Analysis?
Scaling analysis answers a question that gets asked constantly: is scaling into or out of positions actually helping you?
A lot of traders assume that adding size as "confirmation" builds during a trade adds alpha. But when you compare First Exit PnL vs Last Exit PnL across your historical data, you sometimes discover that the scale-ins were actually diluting the superior positioning of the initial entry.

First Exit PnL vs Last Exit PnL
TradesViz distinguishes between two calculations in multi-timeframe exit analysis:
First Exit PnL
Simulates exiting ONLY the first execution at various time points. Ignores all your subsequent adds/scaling.
Last Exit PnL
Moves only the LAST execution (your actual exit) to various time points, considering the full position from all your scaling activity.
Example: When Scaling Hurts
- First execution: Buy 50 shares @ $185.00
- Second execution (scale-in): Buy 50 shares @ $186.50
- Actual exit: Sell 100 shares @ $188.00
Blended cost: $185.75, total profit = $225
But if you had just held the original 50 shares to $188.00:
- Profit = $150 on half the capital
- The scale-in added $75 of profit but required $9,325 of additional capital
Was that worth it? Run this across 100+ trades and your data will tell you.
What to Look For
| Pattern | Interpretation |
|---|---|
| First Exit PnL consistently > Last Exit PnL | Your scaling is diluting returns. The initial entry was better. |
| Last Exit PnL significantly > First Exit PnL | Scaling is adding real alpha. Your adds are well-timed. |
| Both curves look similar but Y-axis differs | You're trading more size for marginal improvement. Capital efficiency problem. |
Practical Application
The goal isn't to stop scaling entirely. It's to know whether your scaling is generating real alpha or just making you feel busier.
If scaling is hurting: Consider trading the initial size with a wider target instead of adding.
If scaling is helping: Look at WHEN in the trade you're adding. Can you refine the timing?
Compare the equity curves side by side. Sometimes they look identical in shape, but the Y-axis tells the real story: you're risking 2x the capital for 1.3x the return.

Example
First entry: 50 shares at $185.00. Scale-in: 50 shares at $186.50. Exit: $188.00. The scale-in added $75 profit but required $9,325 extra capital. Over 100+ trades, data shows whether this is worth it.
