The answer to the question below is;
"It is a parallel trendline drawn from an intermediate peak parallel to the primary trendline. It's kind of a Measured Move."
To understand trendline one must first understand support/resistance level represented by a horizontal line. The line is no magic line. It is not the memory of the Market. It needs not be drawn and publicized to through the media to the mass. It is in the memory of the Market participants. Why?
Support/resistance level is usually the turning point of the Market, whether a peak or a trough. Why participants remember peak and trough price? It is at that price that they lose money or opportunity. They buy at the top or sell at the bottom. So they remember the price. Buyer at the top will wait until the market returns to the top near their buying price and sell. Thus the resistance level. Top with large volume will have significant resistance. Seller at the bottom will be waiting at the bottom to buy hence the support. Bottom with large volume will be a great support.
Why resistance trendline trends downward?
Because some top buyers average down, so they can sell at lower and lower price as time goes by.
Why support trendline trends upward?
Because as time goes by more and more bottom sellers decide to buy above their selling price because they are afraid the price would not come down to their break even price.
No magic.
If the rate of change of break even price is constant we can use trendline. If not we may have to use moving average instead.
