About the candle not touching part, i had asked the same question to SH in other thread and honestly i was still confused after reading his reply. These are unpredictable like the markets you cannot tell what is next but it serves as a good signal.
If you take the base ema i.e. 15 in 315 and 34 in 534 consider its direction as a trend. If its angle is quiet steep then you can chuck the current non touching candle.
Or you can always wait and watch if the second day candle open's above or below the first one.
