DislikedThe problem is that volumes can suddenly change, so say market has low volume and you use RSI-2, place a trade and then suddenly volume picks up.
But it maybe something too look at combining volumes/volatility etc.
Personally I would combine with market sessions. i.e. trading XXXJPY pairs between 16.00GMT and 22.00GMT = RSI-2, 23.00GMT - 07.00GMT = RSI-3 or RSI-5 etc etc. Dont forget that a currency will have most volume/volatility during its normal market hours and lower outside of it.Ignored
During out of market hours for both currencies in a pair use RSI2 (eg. EURNZD @ 18GMT)
Bump up the RSI by one for each currency in the pair that is actively being traded (RSI3 for EURJPY @10GMT, AUDUSD @ 1600) (RSI4 for AUDJPY @ 1GMT, EURUSD @ 13GMT)
