Zip Co Pre/Post Announcement Analysis (practise)

With no qualifications to do this I had a quick look at the last two Zip Co announcements - specifically the 10-11 trading days before and the 5-6 days after. Then replicated a similar scenario for the upcoming EGM and FY20 Annual results. Here is what it looks like.

Please don't jump on me; I am merely a beginner when it comes to TA. Having a go and trying to contribute value to this forum. Keen to know what you think of it.

I know the context of the upcoming announcement is very very very different to the last two and so happy to provoke conversation about how exactly it will be different
