System Description: Cayman is a mean-reversion (countertrend) swing trading system that recognizes high-probability reversal points in up and down trends. Cayman enters the market long or short with one contract and exits after pre-determined criteria are met. Only very high-probability setups are used to enter the market, which is reflected in the high winning rate of the system. Cayman works on other indices markets with the same basic code and logic, which makes it a very robust system. Our system development process utilizes (amongst others) industry-standard walk-forward, distribution and in-depth Monte Carlo analyses.
