What pattern are you suggesting this is? Butterfly? Just an FYI, these types of patterns don't have any predictive power until the pattern has been completed at point D. Maybe there will be a turn at C. Maybe not. However, once the pattern completes at D, an opportunity to short exists as long as the pattern is not invalidated. To trade the different legs of the butterfly before it is completed is just gambling. What other criteria do you have that point to a long entry at point C?
