Timeframe: H1 or H4 preferred but will work on any. If you start using some of the indicator filters, you should stick to H4 or H1.
Currency Pairs: You can trade just about any non exotic curreny pairs with reasonable spread. These have been the best performers: GBPUSD, EURUSD, USDJPY, USDCHF, USDCAD, AUDUSD, EURGBP, EURJPY, EURCHF, NZDUSD
DO NOT TRADE: EURNZD, GBPJPY, EURAUD, EURCAD, GBPCHF
I think it is one of the best EA
