DeMark Sequential (work in progress)

Here you can post and download custom indicators. PLEASE: Do not start topics unless you are posting your own indicator, they will be moved to appropriate section even if you do.

Is it possible for someone to fix this indicator (demark.lua) to function properly with the new TSII platform update? It does not stay up to date with current time. Any of the versions would be great, please! Thank you in advance.

hello all
if your were interested, you could also check my first post
"Adaptive TD Sequential" the TDI indicator.

With regards to recycling, I believe the requirement is that a completed set up inside the countdown goes on to form a clear run of 18 successive closes which all exceed the close 4 bars ago - in other words, two setups, back to back, in the same direction, which start inside the countdown. I think the countdown then starts from bar 9 of the first of these setups. Hope this is of some use to you coding guys.

With regards to Combo, I wouldn't worry about it here as it is an indicator in its own right, and will probably confuse things. Also it doesn't use the recycle, which would further complicate any attempt to create a unified indicator from these two distinct ones.

Re: Version 1.4 with Countdown

Hope i unsterstand the Countdown correct.
A Countdown ist start , if perfect buy or sell setup occur.
A buy Countdown stops, if a new perfect sell setup occur and reverse for sell countdown.

please check the code and let me know.


Countdown is a bit complicated. It can start any time after a completed setup (perfect or not). The rules for cancelling or re-cycling a countdown are quite complicated so I have only included the most basic ones here: The countdown is cancelled if a setup occurs in the opposite direction (marked with 'X'). Countdown returns to 1 if a setup occurs in the same direction (for programming simplicity).

The code for version 1.4 is shown below. This is more or less a complete basic DeMark sequential indicator. As mentioned above, the real DeMark indicators have a lot of extra, subtle rules. This indicator is very similar to a DeMark sequential indicator, but it is not a proper TD Sequential indicator. Please use with caution.

In particular, remember that the purpose of the indicator is to try to predict trend exhaustion (reversal), which means you're trying to pick the top or bottom. This is always going to be a risky business. For best results, use this indicator together with any momentum indicator that you trust. Do not enter a trade if the current move clearly still has momentum. This indicator can quite brilliantly pick a top or bottom sometimes, but it can also really stupidly keep telling you to get in against a strong trend.

Enjoy using it, and please post your experiences in this forum for us all to share.

Tortoise.

   This indicator is a work in progress.
   It is a collaborative effort being written by users on the FXCodebase.com forum,
   based on chapter 1 of Jason Perl's book 'DeMark Indicators' (Bloomberg 2008).

   All users are welcome to use and modify the code, but please would you be kind enough
   to post your improvements and experiences on the FXCodebase.com forum so that we can
   all benefit from your experience.

   TRADEMARK NOTE:  All the DeMark indicator names consisting of "TD" are registered trademarks.
   Would users modifying the code please be careful to avoid using these trademarks, unless you
   have written permission from Market Studies or Thomas DeMark.
   Our intent is to use the ~logic~ behind Tom DeMark's indicators, not necessarily to exactly
   replicate the real DeMark indicators.

   This is version 1.4
   Version 1.2 was the first shared version.  It contained the 1-9 setup count and setup trend levels.
   Version 1.3 included 'perfected' setup.
   Version 1.4 includes the 1-13 countdown.  A completed buy or sell countdown results in a basic
   buy or sell signal.  The countdown is cancelled if a setup completes in the opposite direction,
   and it starts back at 1 if a new setup completes in the same direction.

After finish reading both books by him and Tom Demark as well, I realize that there is a big different btw them. Tom said the countdown not begin if set up not finish And INTERSECTION NOT OCCURS (The new science of Technical Analysis,TD, p.151). I recommend to read straight to Demark's books rather than the one by another author trying to interpret what Demark truly saying

Hope someone notice that and code accordingly.Thanks

Great work on this so far, I was wondering if we could get a mt4 version of DEMARK_V1.lua it would be greatly appreciated. I am very interested in the tdst lines as they appear in trading station
