Your First Tool: The Asymmetric Filter

I don't want you to finish this chapter with just concepts. I want you to finish with something you can use tomorrow.

Here's the Asymmetric Filter — six questions to ask before any trade or investment. If you can't answer all six with specific numbers, you're not ready to enter. Period.

The Asymmetric Filter

Before ANY trade, answer these six questions:

1
WHERE DO I ENTER?
Specific price. Not "around here." A number.
2
WHERE IS MY STOP?
The price where your thesis is wrong. Entry minus stop = your RISK per share (R).
3
WHERE IS MY TARGET?
The price where you take profit. Target minus entry = your REWARD per share.
4
WHAT'S MY R:R?
Reward divided by Risk. If R:R < 3:1, PASS. Wait for a better setup.
5
HOW MUCH DO I RISK?
Maximum 1-2% of total account on this trade. Account size × 0.01 = max dollar risk. Max dollar risk / Risk per share = position size.
6
WHAT NEEDS TO HAPPEN FOR ME TO BE WRONG?
Define it BEFORE you enter. If that thing happens, you exit. No negotiation.
If you can't answer all six with specific numbers — or the R:R is below 3:1 — DO NOT TAKE THE TRADE.

Let me show you how this works with a real example.

You're looking at a stock trading at $50. It's pulled back to the 50-day moving average, which has acted as support three times before. You see a setup.

  • Entry: $50.00
  • Stop: $48.50 (below the moving average and the last swing low)
  • Risk per share: $1.50
  • Target: $55.00 (prior resistance level)
  • Reward per share: $5.00
  • R:R: $5.00 / $1.50 = 3.3:1

That's above the 3:1 threshold. Now size the position:

  • Account size: $50,000
  • Maximum risk (1%): $500
  • Position size: $500 / $1.50 = 333 shares
  • Total position value: $16,650 (33% of account — the size is determined by the risk, not the other way around)
STOP $48.50 -$1.50 risk ENTRY $50.00 TARGET $55.00 +$5.00 reward R:R = 3.3:1 ✓

Before you enter, you know exactly what you'll lose if you're wrong ($500, or 1% of your account) and exactly what you'll make if you're right ($1,665, or 3.3% of your account). The math is asymmetric. The trade is worth taking.

Now compare that to how most traders enter: "This looks good, I'll buy 500 shares." No stop defined. No target calculated. No R:R computed. No idea what they're risking. That's not trading — that's hoping with a brokerage account.

The Asymmetric Filter turns hope into math. Every chapter in this book teaches you to answer these six questions with more precision and more confidence.

Key Principle
"The goal isn't to be right — it's to be asymmetric. A trade with 3:1 R:R only needs to work 1 out of 4 times to break even. That means you can be wrong THREE times and still not lose money. Find that edge. Size it correctly. Repeat for decades. That's the entire game."

The Asymmetric Scorecard

The Asymmetric Filter gives you the math. But a trade isn't just math — it's also context. The best R:R in the world means nothing if the market environment is wrong, your analysis is thin, or your head isn't right.

That's why I use the Asymmetric Scorecard. It takes the filter's six questions and adds the context that separates a calculated bet from an informed one.

The Asymmetric Scorecard

STEP 1: IDENTIFY
Is there a setup with defined risk and open reward?
Entry: _____   Stop: _____   Target: _____   R:R: _____ (must be ≥ 3:1)
STEP 2: CONFIRM
How many confirming signals support this trade?
☐ Price action (trend, structure, pattern) ☐ Indicators (EMA, RSI, volume) ☐ Order flow (delta, absorption, exhaustion) ☐ Regime (trending + favorable volatility) ☐ Macro/sector (tailwind, not headwind)
Confirmation count: ___ / 5   (3+ required. 4+ = high confidence.)
STEP 3: SIZE
Risk per trade: 1-2% of account. Position size = Max risk / Risk per share.
Confirmation 4-5: full size (2%) • Confirmation 3: half size (1%) • Confirmation <3: PASS
STEP 4: EXECUTE
☐ Order placed with stop attached ☐ Target set (or trailing stop plan defined) ☐ Journal entry written BEFORE entry
STEP 5: PROTECT
☐ Portfolio risk checked (<6% total open risk) ☐ Correlated positions identified ☐ Circuit breaker rules reviewed
ALL STEPS COMPLETE = TAKE THE TRADE   |   ANY STEP INCOMPLETE = WAIT OR PASS

You don't need to memorize this now. Each step maps to specific chapters in this book:

  • Step 1 (Identify) — the Price Action, Indicators, Sector, and AI chapters: Finding setups with defined risk and outsized reward
  • Step 2 (Confirm) — the Indicators, Order Flow, Backtesting, and VIX chapters: Validating the setup with multiple independent signals
  • Step 3 (Size) — the Risk Management, Position Strategies, and Professional Edge chapters: Calculating position size based on risk, not excitement
  • Step 4 (Execute) — the Entry, System Building, Psychology, and Execution chapters: Entering precisely and managing without emotion
  • Step 5 (Protect) — the Hedging, Leverage, System, Sector, and Validation chapters: Defending your capital so you survive to take the next asymmetric bet

By the time you finish this book, you'll fill out this scorecard instinctively. It will become your pre-flight checklist — the thing you run through before every trade, every time, no exceptions.

I'll reference it throughout the book. When you see me say "Step 2 of the Scorecard" or "this is a confirmation tool," you'll know exactly where it fits.

The Scorecard isn't just a framework. It's the book in one box.


What's Next

This chapter gave you the game (positioning, not predicting), the principle (asymmetric R:R), the enemies (noise, emotion, complexity), the pillars (technical edge, risk architecture, mental fortitude, intentional integration), and your first two tools (the Asymmetric Filter and the Asymmetric Scorecard).

That's the foundation. Everything from here builds on it.

In Chapter 2, we'll stand on the shoulders of the traders and investors who mastered asymmetry before us — and extract the timeless principles that still work today.
