He also looks for the M15 bollinger band crossing the 3 H2 bands (kindoff "oversold" or "overbought" indication) or candles with wicks getting out of the outer black Bollinger (StdDev 3). In this case the TP is set at the Kijun. For an extra trade confirmation, he also looks the opposite side of the M15 Bollinger, to check whether it is touching the 2H bands. Depending upon the pair, it may be worth waiting for a contact with the outer band (GBPUSD for example which is said to react when candles are touching the outer band)
I'm trying to formalize the whole concept, have to try on a demo account.
