Risk calculations with visible assumptions
RiskKit is a free collection of trading calculators and simulations designed to help visitors examine position size, expectancy, loss sequences and portfolio paths before taking risk.
The tools produce educational estimates from inputs you choose. They do not connect to a broker, place trades, provide signals or promise profitable results. Broker contract details and live execution can differ from the model.
How the tools are built
Each calculator states its inputs and underlying assumptions alongside the result. Position sizing depends on your account risk, price distance and the instrument's contract value. Expectancy reduces an assumed average win and loss to an average R per trade. The losing-streak tool assumes independent outcomes at a constant win rate. The Monte Carlo tools sample many possible sequences and apply a fixed-risk or fractional-Kelly sizing rule after each trade.
Those simplifications matter. A positive expectancy does not make the next 100 trades profitable. A Monte Carlo percentile is one sampled outcome, not a forecast. A calculated stop-loss amount does not guarantee the broker will fill at that price.
Read the methods before relying on a number
The Monte Carlo guide explains equity paths, percentiles and the chosen ruin floor. The losing-streak guide separates the chance of the next run of losses from the chance of a run anywhere in a trading horizon. Both include worked examples and model limits.
For prices and contract specifications, use your broker's current information as the final reference. The homepage's exchange-rate feed is a reference conversion, not an executable trading quote.
