Whether you are managing a high-value personal account or passing a Prop Firm challenge (FTMO, Funded Next, etc.), one single lot size error can blow your account. Trader Pro eliminates the guesswork, allowing you to calculate your exact position size, risk-to-reward ratio, and margin requirements in under 2 seconds.

Keep your funded accounts safe. Track and monitor your daily drawdown limits in real-time to ensure you never violate prop firm rules.
