Finally we have a couple of versions of the CDR tool. These are not in the league of the above and are not really in my personal toolkit but I developed them to make them easy to study and evaluate. My research found the CDR is no more accurate or reliable than other tools I already use and I don't need it to support my methods but it may prove very useful to those attempting to closely emulate ICT. Note that ICT regularly refers to this tool quite incorrectly as showing standard deviation. Anyone who understands mathematics or statistics knows that he must be understood as talking colloquially. ICT has proven himself to be a good enough technician and trader (not to mention all round good bloke) to be forgiven his few peculiarities. There is a version that cannot cope with bridging days but is evidently useful on some index charts. A second version handles crossing over zero hour UTC with no problems
