WRB move is reversed only in following three conditions.
1) We get a WRB after a sustained long and strong move,low volumes and we get a resting bar after WRB and cracking of this resting bar low is a signal to reverse.
2) WRB after a consolidation could be reversed only if its low is cracked in subsequent bars.
3 ) WRB after consolidation and the next bar is a resting bar which closes below 50 % of WRB ( we are talking of bullish WRB here ) and the low of this resting bar is cracked subsequently.Then we reverse.
