About this app

Enter your balance, your risk and your stop, and the lot size comes straight back. Every calculator does that much. What happens next is the difference: the same screen shows the risk you have already spent today and how far the account sits below its peak. It sizes the account, not just the trade.
Your lot size, today's risk budget, and the prop firm limit that binds it.
