To add to what Alt Tab said, the various threads in the ATT stream evolved over several years depending on the audience, questions and participants.
Support and Resistance was a core part of the beginning comments and the most important take-away from the discussion was that location was a key part of the template. Taking a trade through or from a level presented better risk and return opportunities than playing the middle of a range, at least for those who were using that template.
3 Ducks in its purest form doesn’t consider location or S+R but if you find adding it into the template gives you a positive outcome that meets your risk criteria and trade objectives then go for it. Like all filters or elements you add to a template, there will be trade off which you need to assess in line with how you intend to approach the market - short visits or multi-handle trend plays, close or loose risk, etc. There’s no right answer or magic bullet here or in the threads, as what suits one person may not have a positive outcome for another.
Certainly both the pure S+R plays and 3 Ducks continue to be profitable templates to use for me.
