Hi Nagzu..thanks for the kind words...now it's your turn to come in and take charge of things here soon!
When we speak of a breakout here, we are concerned with the dynamic processes that play out at the verge of the breakout itself.
In your example of D-Link, this action would have taken place at 128 where the consolidation and breakout occured. Later in the new uptrend, 142-145 are points of short term divergance, as there is a double bottom here. Similarly 155 too is a divergance level as twice there the price moved down, including forming a double top here. The current price action is the continuation of the intermediate uptrend that started at 128.
The point of the breakout is not necessarily a stop loss should the breakout seem to be failing. The previous weekly high or low would act as immediate supports in most conditions.
Also, a key level at times is not a singular exact point. It can often be a bit of an orb on either side of the point. Say, if 128 is a long term resistance, during critical price action this could stretch to 125-128-130.
Hope I was clear? Do comment.
Regards.
