About the site โDanFin is a free set of tools and honest guides for prop firm traders. Instead of signals or "get funded fast" promises, it gives you the maths: the real probability of passing a challenge, the right size to trade, and the odds behind the decisions most people make on gut feeling.
The pass rate simulator runs a Monte Carlo model over thousands of possible trade sequences to estimate how likely your strategy is to pass a specific firm's rules. The payout simulator does the same for the funded phase, estimating the cash a funded account could realistically pay out. The position size, Kelly criterion and drawdown recovery calculators turn your own numbers into concrete decisions: how much to risk, what a drawdown really costs, and what it takes to recover. Every tool shows its method and its assumptions, so you can check the reasoning instead of taking it on faith.
The prop firm space runs on hype and survivorship bias: the winners get amplified, the losers go quiet, and the gap fills with people selling certainty they do not have. DanFin is built to do the opposite, show the real odds before you pay, be honest about the risks and the limits of every model, and treat you as someone capable of deciding for yourself once you can see the numbers. The guides and articles are grounded in research, statistics and primary sources rather than opinion.
