Hi everyone,
I was just reading up on Elliott Waves and have a simple question:
If we’re in an uptrend, the price moves up in 5 impulse waves and corrects itself with another 3 waves. How does the market change into a downtrend afterwards (not only the correction)?
The last wave of the correction should be down. If the downtrend follows right away, how can I know where it starts and where wave c ends?
Tbh, I don’t really use Elliott waves cause I also find them very confusing. 
BUT you might wanna look at these threads for additional knowledge on this. 
I think, although not exactly the answer to your question, you will have an idea from the discussions.
