162-166 is between the .618
and .786 fib levels of w1.(typically a w2 will move within w1). Can it go even further down , absolutely possible. I'm not sure what exactly you are looking for? If you need an exact number I'm afraid that won't be possible as I don't know what the market is going to do.
Thanks for posting though. Any more questions u might have feel free to let me know
and I'll do my best to try to help you out " dirt"
Good trading
