Fast reversal, heh?
Let's do the next. About Hydraulic bla-bla-bla and Diplomatic channels of emas.
Ema5 quickly reaches target level of ema240. Ema21 is naturally above. Well IF next target is below - the slave ema5 will call the master. IF next target is above - the master will call the slave.
And remember guru, those levels are simply floating support/resistance lines, that CAN be broken or CAN NOT be broken.
