The support is provided by the 50 percent projection level of a wave c from $3.54-1/2. This wave may end around either $3.69-1/4 or $3.78-3/4.
The wave failed three times to overcome the barrier at $3.69-1/4. Chances are it may have ended around $3.69-1/4, or its first part has ended around this level. A break below $3.66-1/2 could confirm the completion of the wave c.
A break above $3.69-1/4 could signal the extension of the wave c towards $3.78-3/4. A more realistic target will be $3.73.
