Many pattern fail and you have to be prepared to take controlled affordable losses when engaging them. But when they do fall in your favour, they could be big earners.
As always, these patterns do not 'predict' - they create probabilities. For every estimate on probability in one direction there is a residual probability that it won't work for you. That's where the stop-loss comes in.
Strang things can happen with these - based on experience.
1 - the pattern fails completely.
2 - a second right shoulder develops (usually in markets).
3 - price stalls in a range for a long time.
