GridZilla is a fully automated EA that uses a proprietary grid algorithm based on common inherent properties of Forex cross currency pairs. The main focus while developing the EA was maximal generalisation to avoid a typical grid systems problem of overfitting to market data. To do that, the genetic annealing algorithm was used together with walk-forward optimisation on over 100 years (!) of market data
The EA was developed using a walk-forward optimisation methodology with in-sample data of only one cross currency pair (AUDCAD), using quotes for the other 5 pairs as out-of-sample data. That allowed us to use the same algorithm and the same optimisation parameters for all traded cross pairs, thus solving the overfitting problem. So, instead of using generally useless Monte Carlo tests, EA’s robustness was proven in real trading for over 100 years of market M1 data, as well as on 60+ years of real tick data with variable spreads
