New trader looking for insight

I am new to the stock trading game and I picked the absolute wrong time to get in on Atlassian shares, so if anyone has information on what's going on or what to expect, it would put me at ease to know. To my inexperienced eye, it appears that recent rises in share price occurred due to a speculative bubble which burst when the company reported average sales and it was undervalued by Morgan Stanley. Should I expect the trend to return to its original form, outlined by the green line, or will it keep going down?
