Position Size Calculator Mt5 Free Download

This position size calculator for MetaTrader 5 (MT5) helps traders determine the optimal number of lots to trade based on their account balance, risk tolerance, and stop-loss distance. Proper position sizing is essential for effective risk management in forex and CFD trading.

What is Position Size?

Position size refers to the number of units (lots) you trade in a single transaction. Proper position sizing ensures that each trade represents a small percentage of your trading account, helping to manage risk effectively. The key principle is that no single trade should risk more than 1-2% of your account balance.

In MetaTrader 5, one standard lot equals 100,000 units of the base currency. For example, trading EUR/USD with 0.1 lots means you're trading 10,000 EUR.

Why Position Sizing Matters

Effective position sizing helps traders:

Control risk on each trade
Preserve capital during losing streaks
Follow a consistent trading plan
Avoid overleveraging your account

Common Mistakes

Avoid these common errors when determining position size:

Trading too many lots on a single trade
Ignoring stop-loss levels
Not adjusting position size with changing account balance
Emotional trading based on recent wins

Formula Used

The position size is calculated using this formula:

Position Size (lots) = (Account Balance × Risk Percentage) / (Stop-Loss Distance × Pip Value × Contract Size)

Where:

Account Balance = Your trading account balance
Risk Percentage = Your acceptable risk per trade (e.g., 1%)
Stop-Loss Distance = The distance between entry and stop-loss in pips
Pip Value = The value of one pip in your base currency
Contract Size = Typically 100,000 units per lot

Worked Example

Let's calculate the position size for a EUR/USD trade with these parameters:

Account Balance: $10,000
Risk Percentage: 1%
Stop-Loss Distance: 50 pips
Pip Value: $0.0001 (for EUR/USD)
Contract Size: 100,000 units per lot

Position Size = ($10,000 × 0.01) / (50 × $0.0001 × 100,000)

= $100 / ($0.05 × 100,000)

= $100 / $5,000

= 0.02 lots (or 20,000 units)

This means you should trade no more than 0.02 lots (20,000 units) for this EUR/USD trade to risk only 1% of your account balance.
