Quote from OneFive:
I'm not a strict disciple of ACD but incorporate pieces of it in a system I am currently trading. Would like to find time to get more involved with it but you know how trying to find time goes.
I'm curious if the number lines any of you keep had been indicating index weakness prior to yesterday's 90% down day which I think is the first one of those we have seen in quite a while.
Thanks, John
Great question and the answer is yes! One of the best parts of the ACD system is the number line divergence. This is one of the areas where this really shines and where you are actually getting information that I believe other traders are NOT getting by analyzing price alone.
For example, on this last move, we saw some crazy divergences in the sector numbers lines. A few were very strong and continue to hold up really well on this sell off (healthcare, homebuilders, financials, transports) but many were getting absolutely crushed. What was odd about this last leg up was the index number lines were sharply negative while price was making higher highs.
Oct. 5th marked the previous swing high in the ES at 1466.
Here is what my 5 day lines were showing on the 5th.
SPY 0
DIA -1
QQQ -5
IWM -7
Those are NOT values you want to see when markets are making swing highs! In fact the nasdaq leading into that high had these values in reverse order: -3, -2, -5, -7
The nasdaq was already showing that it was breaking down. As I mention to Shan yesterday on the oil trade, these number lines in my opinion are giving you MORE information then the straight up weekly and monthly A values. The number lines are giving you the "health" of the market. In many ways you could say it's similar to market breath. Where technicians look at advancers vs decliners as price makes new highs.
Let me give another great example. The previous swing high in oil at at 100. Now in this case, that 100 level on 9/14 was also the failed monthly A up. But the 5 day momentum line was at -2! But they were even worse on the rally up to 100. Here are the values counting backwards going into the swing high: -2, -6,-7, -9, -9, -8
That's what the 5 day was showing you as oil was trading into par! Again, I have found these divergences to give one far more info then simply looking at the chart and drawing a trendline or making note that price is making higher highs and higher lows.
One more example. Gold. Gold traded up to it's swing high also around 10/4 and 10/5. The magical 1800 level everyone was watching. That also was right around the monthly A up. But let's look at the 5 day values leading into the 5th starting with 9/28: -3,-2, -1, 0, -2
So as Gold was trading higher and looking like it was going to break out above 1800, the number lines were telling you exactly the opposite!
One of the leading tells you have that price is bottoming is when you see the market making new lows but the 5 day number lines starting to move from negative to positive. Again, people are still panicking and trying to get short and the number lines are telling you to start buying. Same process in reverse.
