Tick Math, Expectancy, R-Multiples, and Why Win Rate Alone Means Nothing

If you want to trade futures professionally—especially in a prop environment—you must master one skill above almost everything else:

You must understand exactly how money is made and lost, before you enter the trade.

Most beginners look at a chart and think in vague terms:

“This looks like it could go up.”
“I’ll take a small stop.”
“If it moves a bit, I’ll make money.”

Professionals don’t think like that.

Professionals translate every trade into:

ticks,
dollars,
risk,
reward,
probability,
and most importantly: expectancy.

This chapter will make you dangerous in a good way:

You’ll know how to calculate P&L instantly.
You’ll understand why some traders with a low win rate still make money.
You’ll learn how to use R (risk units) to become consistent across markets.
You’ll build a sizing approach that fits prop rules and protects your capital.

10.1 The foundation: P&L is just tick math

In futures, profit and loss is mechanical.

P&L = (ticks moved) × (tick value) × (number of contracts)

If you remember only one formula from this book, remember that.

Because it gives you control.

You stop being surprised by losses.
You stop being shocked by profits.
You can plan your day like a business.

10.2 What a “tick” really means (and why beginners misjudge it)

A tick is the smallest price movement allowed in the contract.

But to you, a tick is not a “market concept.”
A tick is a unit of money.

10.2.1 Why beginners underestimate ticks

Beginners think:

“It moved only a little.”

But “a little” can be 20 ticks.

And 20 ticks can be:

$100 per contract,
$500 with 5 contracts,
or enough to hit a daily limit.

Professionals don’t say “a little.”
They say:

“That was 20 ticks. I can handle that.”

10.3 Tick value: the one number you should never trade without

Tick value is how much money you gain/lose per tick per contract.

If tick value is $5:

10 ticks = $50
20 ticks = $100
50 ticks = $250

Now multiply by contracts.

This is why sizing matters more than entry.

10.4 The stop-loss is your “cost of doing business”

Your stop-loss defines:

the maximum planned loss of the trade.

That’s important:
planned loss, not “hope loss.”

10.4.1 Risk per trade (in dollars)

Risk per trade = stop ticks × tick value × contracts

Example:

Stop = 12 ticks
Tick value = $5
Contracts = 2
Risk = 12 × 5 × 2 = $120

That is the cost of being wrong.

If you cannot emotionally accept that number, you’re trading too big.

10.5 Reward: what makes the trade worth taking

Before you enter, you should estimate:

what the market could reasonably give you.

Reward depends on:

structure (next resistance/support),
volatility,
session behavior,
and your management plan.

Reward (in dollars) = target ticks × tick value × contracts

10.6 Risk-to-reward ratio (R:R): helpful, but incomplete

Beginners worship risk-to-reward.

They think:

“If I do 1:3, I’ll be rich.”

Not necessarily.

A trade with 1:3 reward but only a 20% win probability can still lose money.
A trade with 1:1.2 reward but a 70% win probability can be very profitable.

So R:R is not enough.

Professionals care about expectancy.

10.7 Expectancy: the real engine of profitability

Expectancy is your average outcome per trade.

A simplified expectancy formula:

Expectancy = (Win% × Avg Win) − (Loss% × Avg Loss)

If expectancy is positive, you have an edge.
If expectancy is negative, you are donating.

10.7.1 Why this matters more than win rate

A trader can win 80% of trades but still lose money if:

their average loss is huge,
and their average win is tiny.

Another trader can win 40% but make money if:

their losses are controlled,
and their wins are large.

Win rate is a number.
Expectancy is the business model.

10.8 R-multiples: the professional way to measure results

Pros often track results in R, not dollars.

R = your risk per trade

If you risk $100 on a trade:

a $100 loss is -1R
a $200 win is +2R
a $50 win is +0.5R

Why this is powerful:

It standardizes performance across different markets and sizes.
It prevents you from “feeling big” on one trade and “small” on another.

It keeps your mind focused on process.

10.9 Example: two traders with different win rates

Let’s compare two traders over 10 trades.

Trader A

Win rate: 70% (7 wins, 3 losses)
Avg win: +0.5R
Avg loss: -1R

Expectancy:

(0.7 × 0.5R) − (0.3 × 1R)
= 0.35R − 0.30R
= +0.05R per trade

Over 10 trades: +0.5R
Not huge, but positive.

Trader B

Win rate: 40% (4 wins, 6 losses)
Avg win: +2.0R
Avg loss: -1R

Expectancy:

(0.4 × 2R) − (0.6 × 1R)
= 0.8R − 0.6R
= +0.2R per trade

Over 10 trades: +2R
Much stronger edge.

Trader B wins less often but makes more money.

This is why “win rate” is a trap.

10.10 Position sizing: how pros choose contract count

Sizing is the bridge between expectancy and real money.

If you size too big:

you break rules,
you panic,
you abandon the system.

If you size too small:

learning is slow,
but survival is easy.

Professionals size based on risk.

10.10.1 Fixed risk sizing (best for beginners)

Choose a fixed dollar risk per trade.

Example:

Risk per trade = $50
Then contracts are calculated each trade based on stop distance.

This keeps risk stable, which keeps your mind stable.

10.10.2 Volatility-adjusted sizing (advanced)

In more volatile markets you reduce size.
In calmer markets you can increase size slightly.

This requires discipline and experience.

10.11 Prop firm P&L mastery: turn rules into a math system

Prop trading forces you to think like a risk manager.

You must translate:

daily loss limit,
trailing drawdown,
contract limits,
into tick math.

10.11.1 The daily loss budget method

Let’s say:

Max daily loss = $500
You create a budget:
Risk per trade = $75
Max trades = 6 (but you may stop earlier by discipline rule)
Stop after 2–3 consecutive losses

This prevents spirals.

10.11.2 The “R-based daily stop”

Instead of thinking in dollars, think in R:

If you stop after -2R or -3R daily, you protect the account.

This is professional.

10.12 The most important P&L truth: small losses are the price of staying in business

Beginners hate small losses.
They fight them.

Professionals accept small losses as rent.

The goal is not to avoid losses.
The goal is:

keep losses small,
let wins pay,
maintain positive expectancy.

When you do that, you can survive long enough to scale.

1	1	+2.0	good execution
2	1	-1.0	stop hit

End-of-Chapter Exercise (this makes you professional fast)

Answer these with real numbers for your main market:

Tick value = $____
If your stop is 16 ticks, risk per contract = $____
If your max risk per trade is $80, how many contracts can you trade?
If your daily max loss is $500, what is your daily loss in ticks?
Write your expectancy formula and explain what positive expectancy means.

If you can do this daily, you stop trading emotionally and start trading like a business.
