Great thread - I hope you keep it up! Any chance of you posting the DU volume you are watching (for your daily Watch List) so we can compare it to what we are doing, especially since there are several different ways to calculate it?
The discussion regarding an appropriate and quantifiable method to correctly obtain DU Volume began long ago (probably before Jack began posting on Usenet) and continues even today. I use several methods currently in an attempt to determine a 'best' method. To date, no ONE method outperforms another.
Methods for my dry up volume calculations I currently use:
1. A five day average volume before price breakout.
2. A ten day average volume before price breakout.
3. A twenty day average volume before price breakout.
4. Last low volume before price breakout.
The 20 day average closely approximates the chartscript at Wealth- lab
Other methods that have been suggested:
1. 30% of 65 day average volume - suggested by dkm
2. 'eyeball' lowest volume - suggested by Jack in his teachings
3. average lowest volume in six months
Jack advised against using the 'average lowest volume in six months' method in several of his posts.
Equations used by Jack in TC2000:
3 progressive stages of dry up:
((AVGV30 - 3 * AVGV5) > 0) AND (AVGV5 > 0)
Dry Up 1
(AVGV30 > 2 * AVGV3.6 AND AVGV30 > 2 * AVGV3) AND (AVGV3.3 - AVGV3) > 0 Dry Up 2
(AVGV30 > 2 * AVGV6.3 AND AVGV30 > 2 * AVGV3) AND (AVGV6.3 - AVGV3) > 0 Dry Up 3
FRV
(AVGV5 - AVGV30) > 1000 AND (MAXC126 - MINC126) > 0.5 * MINC126
(AVGV5 - AVGV30) > 1000
Exit conditions:
Gainers Over Yesterday Between 5% and 10% Inc.
((C - C1) / C1) * 100 > 5 AND ((C - C1) / C1) * 100 < 10
Gainers Over Yesterday Greater than 10%
((C - C1) / C1) * 100 > 10
Stage 1 or Stage 3
(H30 < 1.1 * L5) AND (H5 < 1.1 * L30)
Stage 2 or Stage 4
((MAXC126 - MINC126) / MINC126) * 100
Gappers
L > H1 OR H < L1 AND V > 1000 OR (C * V) > 2500
Quote from Jack Hershey on Usenet:
Before i buy the lists of stocks comes from the following three equations:
1. ((AvgV30)-3*AvgV5))>0 AND (AvgV5>0)
2. (AvgV30>Avg3.6 AND AvgV30>2Avg3) AND (AvgV3.3 - AvgV3) > 0
3. 9AvgV30> 2*AvgV6.3 AND AvgV30 > 2* AvgV3) AND
(AvgV6.3 - AvgV)>0
the day i buy the stocks appear on the following equation lists:
5. AvgV5 - AvgV30 > 1000 AND (MaxC126 - MinC126) > .5* MinC126
6. AvgV5 - AvgV30 > 1000.
before stocks peak to me sold they appear on these two equation lists:
7. ((C - C2)/ C2)*100 > 5 AND ((C - C2)/ C2)*100 > 10
8. ((C - C2)/ C2)*100 > 10.
I think dkm sums it up best in this quote from another thread:
Quote from dkm:
I have discussed this many times with Jack. There is no formula for DU. All of the above are attempts to define it, and all are equally valid. The principle is simple - a significant reduction of volume, leading to a contraction of price bars and a subsequent breakout.
Rather than providing dry up values and posting them to the journal, I hope individuals will test out various methods for calculating dry up volume - either any of those listed, or other methods obtained from another source. The methods I use do not currently signal a trade every day. Perhaps, someone will determine a BETTER method for dry up calculation that does signal a trade each day.
I hope you find the above information useful.
