Typical levels for the last 5 wave would be between 0.786 and 1.0 of the size of 0 to 3 as measured from 4. These are the lower of the two white lines.
But....looking at the wave 1 of this structure it formed a similar pattern and then exploded. Other fib levels marked.
If this plays out then expect a big drop after it completes.
Remember...always do your own research. Don't just buy something because someone you don't know on the internet says it might be a good idea.
