Kelly Strategy Pro app for iPhone and iPad

Widely used in the gambling community for sizing bets, the Kelly Strategy has proven to be an effective money-management tool for trading stocks.

Developing a viable trading strategy requires an effective money-management technique to maximize the long-term geometric wealth of a trading strategy. The strategy must have positive risk-adjusted expectancy for any money management to be additive. Kelly Criterion, a strategy has a positive expectancy will maximize the geometric growth in returns through the re-investment of profits or trade-to-trade compounding of returns. The Strategy defines a fixed fraction of capital to invest in each trade and is based on the
expectation (probability) of long-term capital growth.

Additional controls incorporated into the Kelly Calculator allow the user to vary the degrees of risk and return with built-in filters. Each strategy is automatically backtested to determine the best equity curve.
