The E-Build is a sideways wedge pattern, here with staggered ABCDE notation, which presages a potential E-Breakout. Often enough the trend direction is unclear until the E-Point is determined, and it may require the B to become A, etc. Nested E-Builds, as in this example, strengthen the move significantly.
Combined with the recent shallow angle uptrend base in JNUG, this entry was both low risk and likely to finish higher than usual. A trading range peak of 22.50 is possible – maybe more.
