Conclusion:
- Choose the instruments with high correlation for positive results. First of all, take note of the indices and futures contracts. Also good pairs are some of the stocks and their privileged variants.
- The higher the costs and less the correlation, the higher the timeframe should be used. For most cases, the optimal timeframe is M30-H4.
- You can not rely on the tester results completely, as the live trading by this strategy often comes with large commission costs. They must be taken into account. For testing use the M30 timeframe or higher, to speed up the process, OHLC can be set to M1
