Strong Resistance for good Short opportunity on CPA.

CPA is in a short term downtrend and is looking like it could possibly continue this downtrend. I have marked the key resistance points for the possible short swing opportunity. I think that there is strong resistance around the zone where I put the yellow box. If price follows the yellow path and breaks the now green support line to go bearish than there could be a good short swing opportunity and the now green resistance line can be used as a S/L on a short position.
