Those looking for a simple technical analysis (TA) could revisit the use of trendline. Its one of the most basic tools. As depicted in the QCOM chart, one could find the potential move of QCOM. Trendline 1 could tell the reader its a confirmed uptrend with at least 3 point of touches by the trendline. Trendline 2 is also a confirmed uptrend with the same 3 point of touches. Trendline 3 is a unconfirmed uptrend and could be a weak one as it only have the minimum 2 point of touches by the trendline. The angle of ascend of each trendline may also tell us the sustainability of the trendline. A more upsloping (near vertical formation) would not sustained the upward move. The ideal upsloping or upward trendline angle would be around the 40 degree angle.
The use of trendline not just restrictive to price action, but it also can be used to determine Volume trend. As depicted on QCOM chart, the volume is drying up by the down sloping of the trendline. A break of the down sloping trendline could potentially pushing up the price of QCOM further high.
Beside using trendline to determine the next up or down trend move of a particular instruments, trendline could also be used as a dynamic support and resistance line. As an example depicted by QCOM chart, Trendline 3 currently supporting the upward move of QCOM price action, but if it fails the next dynamic support could be Trendline 2 and Trendline 1. A price action falls below Trendline 1 could signal a change in trend from Bullish to Bearish.
One need to update his/her trendline from time to time in order to accounts for the latest price action move.
Happy trading guys.
