Skills Lab 02: Pips, Lot Size, Spread and Leverage

Lesson objective
Understand how a small price move becomes real money risk through lot size, pip value, spread, and leverage.

Why this lesson matters

New traders often choose lot size based on confidence, account balance, or what they saw online. That is backwards. Position size is not a confidence button. It is the result of a risk calculation. A trader can have a strong setup and still be dangerous if the stop is too tight, the size is too large, or the spread is ignored.

The core idea

Start with risk, then calculate size. Risk amount comes from account size and risk percentage. Stop distance comes from chart invalidation. Pip value connects the two. Leverage only changes exposure; it does not make a bad risk plan acceptable.

Key terms you must understand

• Pip: the standard unit used to measure most forex price movement.
• Pip value: how much money one pip is worth for your lot size and pair.
• Spread: the cost between bid and ask. It matters most when stops are tight or liquidity is poor.
• Leverage: borrowed exposure. It magnifies position size but does not reduce risk.

The desk process

This is the practical sequence to follow. The order matters because most trading mistakes come from making the entry decision before context, risk, and invalidation are clear.

1. Decide account risk first. A setup does not deserve bigger size because it feels strong.
2. Measure the stop from entry to true invalidation, not to the nearest number that makes the lot size comfortable.
3. Use the pip calculator and then ask whether the trade still makes sense after spread and slippage.
4. Reject trades where the required stop is too wide for the account or too tight for normal volatility.

What good execution looks like

• Know whether the pair is JPY or non-JPY because pip measurement changes.
• Measure stop distance from entry to invalidation, not to the nearest comfortable number.
• Use the pip calculator before the trade, not after the loss.
• Check spread and slippage risk during news, rollover, and low-liquidity sessions.

Walkthrough

Two traders can both risk 1 percent and still use different lot sizes because their stop distances are different. If one setup needs a 20-pip stop and another needs a 70-pip stop, the second trade must use smaller size. If both use the same size, one of them is not respecting risk.

A trader with a small account wants to risk 1 percent on EUR/USD. If the invalidation is 20 pips away, the lot size may be much larger than if the invalidation is 80 pips away. The trade did not become worse because the stop is wider; the position size must simply shrink.

If a broker spread widens from 1 pip to 5 pips during rollover, a 10-pip stop becomes a poor structure. Spread is now half the stop distance. That trade may be mathematically bad even if the chart looks clean.

Decision table

Common mistakes to avoid

• Using the same lot size on every pair and every stop distance.
• Confusing margin used with maximum loss.
• Keeping leverage high because a demo account survived it once.
• Forgetting that JPY pairs and metals can have different pip value behavior.

Try it on a chart

1. Use the pip calculator with the same account size and 1 percent risk.
2. Run three stop distances: 15 pips, 35 pips, and 70 pips.
3. Repeat on a JPY pair and compare how pip value changes.
4. Write one rule: "If my stop is wider, my size must..."

Practice assignment

Do not just read this lesson. The value is in doing the reps and then checking the reasoning. Use demo charts, replay charts, or screenshots.

1. Run 12 calculations: three pairs, two account sizes, and two stop distances. Save the results.
2. Write a personal maximum risk rule and a maximum daily loss rule before taking any demo trade.
3. Take screenshots before and after the decision. Mark the exact candle where your view changed.
4. Write one sentence for context, one for trigger, one for invalidation, and one for risk.
5. Ask the AI tutor to challenge the weakest sentence before moving to the next lesson.

Ask the AI tutor

Ask the tutor to check your sizing logic. Provide account risk percent, pair, stop pips, and what lot size you calculated.

Good tutor prompts include: "What am I assuming here?", "Where is the invalidation?", "Is this location clean enough?", "Give me a drill for this weakness", and "Quiz me one question at a time."

Checkpoint

You pass this lab when you can explain why a wider stop normally means a smaller lot size.
