Three months ago I was introduced to the book "DeMarks Indicators" by Jason Perl. In particular I was interested in TD Sequential and searched the internet for source code that I could copy, adapt and translate into afl. This was not very successful and the best code I could find already existed in the afl library as "TD Sequential" by Abdul Kareem (25/07/2007). Whilst that was very good and I hasten to add, much more efficiently coded than my own version, I concluded perhaps it was not always following the logic laid out in Perl's book. Thus, without much planning and thought I decided to write my own version based on the rules in Perl's book. I have been using my version for a few months now and run it as an indicator/explorer on end of day data. My database is small containing just 150 shares and 5 years of data for each share. I would like to emphasise before anyone considers using this version it is very slow as indicated by afl's 'Code check and profile option'. It is also very long and contains very little 'true' afl code which I suspect may provoke some unfavourable comment. However, that said the code runs fine on my machine and fits my purpose. My reasons for making this code generally available are two fold:- 1) I hope one or two of the better programmers on here will perhaps review the code and improve the overall efficiency making those amendments readily available, and 2) Those that own the above mentioned book and are familiar with Perl's logic may wish to use the program and comment as to whether my interpretation of Perl's logic is correct or not. Finally, a few points to note. The 'R' is displayed as it arises ie. on the eighteenth bar and not the CD thirteenth bar. I also use the old amibroker colour scheme and the colour white is used for both support and resistance lines. Thank you in anticipation of your help in these matters. Chris B
