Using leverage responsibly
The previous lesson explained how the risk–reward ratio compares a potential loss with a potential gain. Leverage adds another dimension: it allows a relatively small amount of margin to support a larger market position. This lesson explains how to separate margin requirements from actual risk and use position sizing to keep exposure within a defined plan.
1. Understand what leverage changes
Leverage allows you to control market exposure greater than the margin required to open a position. At leverage of 1:100, a hypothetical position worth USD 10,000 requires approximately USD 100 in initial margin, assuming a straightforward calculation. Margin is collateral supporting the position; it is not a fee, and it is not the maximum amount the position can lose.
For a fixed position size, changing the leverage setting does not change the profit or loss caused by a given price movement. It changes the margin requirement. The danger arises when lower margin requirements encourage larger positions: the same market movement then produces a larger monetary result. CFDs are leveraged products and carry a high risk of loss.
2. Distinguish available and effective leverage
Available leverage describes the maximum exposure a given amount of margin can support under the applicable conditions. Xellion offers leverage up to 1:2000, depending on the account. This maximum is not a target or a measure of an appropriate position size. Using a smaller proportion of the available capacity can leave more free margin, but does not remove market risk.
Effective leverage compares your actual market exposure with your account equity: effective leverage equals total notional exposure divided by equity. For example, USD 20,000 of exposure against USD 5,000 of equity represents 4:1 effective leverage. Equity includes unrealised profits and losses, so this ratio can rise as losses reduce equity, even if you do not open any additional positions.
3. Worked example: size before margin
Consider a hypothetical USD account with USD 5,000 equity. For illustration, a trader sets a planned loss of USD 50, or 1% of equity, with a stop-loss 25 pips from entry on EURUSD. One standard lot is 100,000 euros, with a pip value of USD 10. Excluding costs and execution differences, position size is USD 50 ÷ (25 × USD 10) = 0.20 lots.
At a hypothetical EURUSD entry price of 1.1000, this position represents EUR 20,000, worth USD 22,000. Using simplified margin calculations, required margin is USD 220 at 1:100 or USD 22 at 1:1000. In either case, each pip is worth USD 2, so an adverse 25-pip move produces a USD 50 trading loss. Higher leverage reduces margin, not that loss. Costs and execution beyond the stop price can increase the actual loss.
4. Assess the whole account
A position that appears manageable alone can become significant when combined with other open trades. Several currency positions may share exposure to the same currency or react similarly to economic news. Reviewing each position separately can therefore understate the account’s combined risk. Total exposure, potential losses across positions and concentration all matter alongside the risk–reward ratio of any single trade.
Free margin is the difference between equity and used margin. It can shrink as floating losses increase, leaving less capacity to absorb further adverse movement. A large free-margin figure does not prove that exposure is safe, especially with high available leverage. In MT5, review equity, margin, free margin and margin level together rather than treating unused margin as a spending allowance.
5. Build a repeatable risk process
A structured process starts with a defined monetary risk amount and a reasoned stop-loss distance, then calculates position size. Margin is checked afterwards to assess whether the account can support that exposure. Increasing leverage merely to fit an otherwise oversized position reverses this logic. A stop-loss is useful for planning, but ordinary stop orders do not guarantee execution at the requested price.
Before placing an order, check the instrument’s contract size, pip or tick value, trading costs and margin requirements. Also consider how gaps, volatile conditions and several simultaneous losses could affect equity. These checks cannot eliminate loss, but they make the relationship between exposure and account resources clearer. The next lesson explains margin calls and stop outs, including why broker-enforced liquidation should not replace a risk plan.
- Leverage changes required margin, not profit or loss per pip at a fixed position size.
- Available leverage is a limit, not a position-sizing target.
- Calculate exposure from planned risk; check margin afterwards.
- Monitor combined exposure and equity; stop-loss execution is not guaranteed.
