Amount at risk: $100.00
Position size: 0.40 lots; 40,000 units

Rounded down to 0.01 lots so the real risk never exceeds your target. Slippage and gaps can cause losses larger than planned; check the contract specification on your broker's platform.

Trading foreign exchange, gold and other leveraged products such as CFDs carries a high level of risk and may not be suitable for all investors. You could lose some or all of your invested capital. Nothing on this website is financial, investment or tax advice, and past performance is not indicative of future results. Only trade with money you can afford to lose and consider seeking independent advice.
