Tools for independent thinking.
Market History Lab is a free, independent educational website maintained by an individual in Romania, not a registered company. It is built around transparent mathematics, accessible explanations and practical financial-risk tools.
Explore the site
Use calculators for acquisition cost, position sizing, risk/reward, P&L and hypothetical recurring investments. Explore the Risk Lab for modeled equity paths and conditional first-passage probabilities, or read our original illustrated learning guides.
Our approach
Show the inputs. Explain the formula. Make limits visible. Differentiate synthetic teaching diagrams from verified market observations. See Methodology and Data Sources.
What this website does not do
Market History Lab is not a broker, adviser or exchange, does not custody user funds, does not provide trade signals or promise investment outcomes. We do not currently publish a licensed live market quote feed or historical backtesting dataset.
Everything here is general educational information, not personalized investment advice. Financial trading, especially with leverage, involves risks beyond those in simplified examples.
