So the question is; which came first, the chicken or the egg?
Jokes aside, charting is partly a self-fulfilling prophecy (enough people following the same rules based on charts will end up causing the expected outcome), partly a mathematical expression of peoples/market sentiment and how to take advantage of this (game theory).
RE question about announcements: My interpretation of the charts is that the market is anticipating something (e.g. an announcement). Consequently, volume has dropped over the past couple months and buyers have been sitting at the support around 0.46-0.48 where the risk/reward calculus becomes appealing. The price has bounced off this line twice. To me the chart appears more like a double bottom pattern (https://stockcharts.com/school/doku...nalysis:chart_patterns:double_bottom_reversal).
