The support is provided by the 138.2 percent projection levels of the wave C, the part of which from the March 4 high of $3.77-3/4 consists of five smaller waves.
The bounce triggered by the support has been driven by a wave 4, which may end around $3.66-3/4, to be then reversed by a downward wave 5.
On the daily chart, the bounce is regarded as a pullback towards a resistance at $3.67-3/4, the 38.2 percent projection level of a downward wave C from $3.97-3/4. This wave is capable of travelling to $3.49-1/2.
A further gain may be limited to $3.68-3/4 (first chart).
