Yes. For one, that wasn't even a trendline before it crossed through the price action. It was above the candles before. What makes you think lines drawn over the tops of candles can act as support later?
expirience. Isn't it obvious that price is reacting to these trendlines (or call it what you want) rightnow. you are probably thinking about classic trendlines that are drawn from low to low or high to high only. what I'm doing is obviously a bit different which doesn't make it wrong as there is no right or wrong. if it makes you money it's right.
