Leverage does not create risk — position size does

Leverage is the most misunderstood idea in trading. Most beginners assume high leverage means
high risk, which is only half true. Leverage does not create risk; position size creates
risk. Leverage only decides how much money you need to open that position.

1. Margin — what leverage actually does

When you open a trade the broker locks part of your capital as margin:

Margin = (Volume × Contract value) ÷ Leverage

Take one lot of EUR/USD (€100,000) at 1.1650:

• At 1:30 → margin ≈ 116,500 ÷ 30 = $3,883
• At 1:100 → margin ≈ $1,165
• At 1:500 → margin ≈ $233

The point: in all three cases the position is still one lot. A 10-pip move is
still $100 either way, whatever the leverage. Leverage changes the capital locked up, not the risk
carried by the trade.

2. So why is high leverage dangerous

Because it permits a position larger than the account can absorb. With $500:

• At 1:30 you can open about 0.12 lots. A 100-pip move against you costs $120.
• At 1:500 you can open 2 lots. That same 100 pips costs $2,000 — more than the account holds.

High leverage does not force you into a large position; it removes the barrier. The risk sits in
the trader’s decision, but the barrier has real value, and that is why the major
regulators cap retail leverage at
1:30.

3. Free margin — the number that governs your next trade

Free margin = Equity − Used margin

This is the capital still free, both to open new positions and to absorb the running losses of
open ones. When free margin reaches zero, your
margin level touches 100% — the
margin call threshold at most brokers.

The common mistake is deciding on a new trade by looking at balance. Balance does not
reflect running losses. The number to read is free margin.

4. Choosing a sensible leverage

The right question is not “what is the highest leverage available” but “how much margin do I need
to run my strategy comfortably”.

• Size the position from risk first. Risk 1–2% per trade and work the lot size
  back from your stop distance.
• Then check the margin that size requires. If margin swallows more than 20–30%
  of the account, either the leverage is too low for the strategy or the position is too big.
• Keep free margin wide enough to survive ordinary volatility without touching a
  margin call.

5. Four situations that raise margin without warning

• Before major events. Many brokers raise margin requirements ahead of
  central bank meetings or employment
  reports.
• Over the weekend. Some raise it for positions held across the break.
• Volatile instruments. Gold and indices usually require more margin than the
  major pairs.
• Larger accounts. Some brokers step leverage down once equity or volume passes a
  threshold.

6. Costs belong in the same equation

Spread and commission are deducted from equity the moment a trade opens, so they reduce free
margin from the first second. For a high-volume trader that is enough to change how many positions
can be open at once.

Which is why cost management and margin management are one problem, not two.
