Trendline

Hi Pat, I just became a VIP member. I am very new to technical analysis and am studying your past videos to get upto speed. The videos and info is great and I am learning a lot. Thanks. I have few questions about your video -  https://missionwinners.com/chart-study/clean-simple-downtrending-pattern-provides-clean-entry/ I have created a trendline in yellow. https://goo.gl/vqBweo https://goo.gl/316M3B 1. At point B, I see pickup in volume and it crossing the MA. Would I be wrong in buying at point B? If so, why? 2. To someone as new as me, the trendline in Yellow looks similar to the trendline in White, was there a reason to ignore the one in yellow and trade using the one in white. 3. Also, is trading using a patterns like cup with handle, flat base less \"risky\" for a new trader than trading using descending trendline? Or it does not matter. 4. I was reviewing this video and I see the keylist is divided into long base and short base - https://youtu.be/Ki7uGeJCj2g Do you still upload the keylist and mark the stocks as long base and short base? Thanks Danny
