NEW Advisory Sell S17.     EDITED 8/24/2013
         Rules: 
                       1)   5 straight DJI down-days
                       2)  June - September
                       3)   DJI within 10% of 12 mo high.

           This
was a powerful and reliable signal before 1948 and mostly before 1990. 
           But it has lost much of its special potency in more recent cases. 
It seems that
           five or 6 consecutive down-days NOW sets up an oversold condition which
           computerized traders cannot resist playing for a short-term bounce.
First see
           how well the signal worked before computerized trading became dominant:

                        September 1929 
9/25/1929 Completed H/S     Extreme bear market followed. ,
                        August 1937
8/20/1937 Extreme bear market followed.
                        August 1941
8/4/1941   Completed H/S. Bear market followed.   ,
                        June 1946
6/6/1946   Almost perfect.  22% decline followed.   
                       
July 1948 
6/22/1948
                        August 1957, 
                        July 1981,
                        September 1987 and
                        August 1990. 

            The same idea - 5 straight DJI down days - should also be watched
            for early in the year.   Mostly this leads to big declines
            1/16/1948 
            2/8/1949 - weak rebound for a month and then down for two months
            1/14/1960
            1/10/1962
            1/19/1973
            1/30/1990 - DJI was already down 9.5%.  This was an intermediate-term bottom.
                                   There were multiple Buy signals here.
             1/25/2000
             1/18/2008 This was intermediate-term bottom DJI was down 15% from high.
               

            This Advisory Sell S17 has caused too many whipsaws since 2000
             to trust as a Sell Signal.   If one studies these cases closely, it is
             sometimes helpful to suppress a Buy B2 in its aftermath (15 trading days)
             because that signal produces only a limited rally when there has been
            an Advisory S17.   That is not true when there is an additional Buy signal. 
            Here are the relevant cases to study:

               
8/12/1938 This was also a B2/B7/B17 and DJI quickly rallies to upper band. 
               
6/22/1948 Head/Shoulders followed. 5-month decline 
                     See how the later Buy B2s might usefully be cancelled by this signal.
 
                6/22/1951 Only Gained +2.1% as Buy B17 given on 6.19/1951
                6/5/1959  Failed DJI fell 2% and rallied 10%.  This shows how hard it is too stop a
                    market with powerful momentum behind it.
                9/8/1987 DJI rose from 2541.12 to 2640 on 10/5/1987 and then crashed.
                   This was a case of a simultaneous Buy B17 with this S17.

   1929-2013:
         44 older cases: 
        
20 declines of 5% or more
          8 declines of 2% to 4.9%
          6 declines of  0.1% to 1.9%

         
10 losses

   Since 2000:
          4 of 11 cases brought declines of more than 5%.
          4 of 11 cases brought modest losses.

9/25/1929 Completed H/S     Extreme bear market followed.
8/20/1937  Extreme bear market followed.
8/12/1938 This was also a B2/B7/B17 and DJI quickly rallies to upper band. 
8/4/1941   Completed H/S. Bear market followed. 
7/21/1943 About to complete H/S. 3 1/2 month shallow decline followed. 

7/19/1944 About to be H/S. New reversing Sell.  DJI declined 2.4% when reversed on 9/6/1944. 
6/6/1945  DJI declined slowly for 2 months only to LB.
6/6/1946   Almost perfect.  22% decline followed.  
6/22/1948 Head/Shoulders followed. 5-month decline  But see how the Buy B2s might usefully be cancelled by this signal.  
6/22/1951 Gain +2.1% as Buy B17 given on 6.19/1951

9/20/1951 Gain  +5.0% upon B17 reversal on 10/29/1951
8/18/1952 DJI fell for 2 months from 274.3 to 263.1

8/14/1957  Big Gain DJI collapsed. 

6/5/1959  Failed DJI fell 2% and rallied 10%.  Best way to have seen that the rally would be bigger than
                expected was to see how the DJI aborted its head/shoulders pattern by going above 640 on its way to 680.
                The NYSED A/D Line downtrend was also broken at this time.
8/10/1959 Gain +2.5%
7/16/1963 Bad but 65-day-up-pct (-.01) was too close to 0.   This is a whipsaw-prone value.
                 The breaking of NYSE A/D Line downtrend and the aborting of the H/D pattern would have limited loss here.
8/25/1964 Bad. DJI broke out and rose from 832.2 to 890 in mid November.
                Best way to have seen that the rally would be bigger than expected was to see how the DJI
                aborted its head/shoulders pattern by going above 850 on its way to 890.

6/30/1967 Bad.  DJI rose from 860.26 to 943.08 before declining.
