Trades a portfolio of 28 currency pairs, comprising the majors AUDUSD, EURUSD, GBPUSD, NZDUSD, USDCAD, USDCHF, USDJPY, and their respective crosses. Re-optimized, back-tested, and ranked every month over previous 13-weeks price history. Rankings determine which of the 28 currency pairs are allowed to trade based on net profit, drawdown, profit factor, etc. Seems to be working quite well.
