"But S&R are provided as a result of price levels created by supply and demend, not by price "touching" a homemade line."
I think that the above is splitting hairs.
No, it's the core of what is meant by support and resistance.
I totally agree about supply and demand.
When a trader decides to take a trade based on trendline s/r he is not thinking much about the price he is looking at the reaction of price to the line. If enough traders are using trend in this manner the supply and demand will react to it and become self-fulfilling.
The same could be said of dozens of other lines, but they don't provide S/R either.
The fact that so often the trendline is the turning point for a price must surely be proof that s/r is provided by the trend as much, if not more so, than it is provuded by the price.
Sorry, no. But since this "debate" with you has gone on for, what, several years now, and you still don't understand what i'm talking about with regard to support and resistance or trend, I suggest we drop the subject. This thread is, after all, not about what trendlines provide or don't provide. If you want to start a new thread about trendlines, please don't hesitate to do so.
