Parallel Backtesting Tool
This tool will run all possible simulations given your chosen time period.
For example if you choose 30 years. The first investment starts back in January 1885, the second in February 1885, the third in March 1885, and so on.
By doing it this way we can run complex statistical analysis and look at probabilities that a single backtest simply cannot deliver.
