blackbelt, who anticipated the 20w low in Dec-04???? - certainly not me - 112 tradings days (which is the upper limit for 20w cycle since 10w cycle is 48-56 trading days) from Aug-13-04 low (which was 80w and all smaller cycle low) was Jan-24-05 - exactly where that big low is.
Futhermore, if you read my posts from Jan-05, you will see that in ealy Jan I was saying that the drop is not done yet, and that we needed more downside into End of January.
