Technical Analysis are very helpful when determining a price point of entry.

However, the market isn't just about what you know, but what everyone knows. It's key to keep up on breaking news and such. Many others could of had the same mindset as you but switched to sell with the recent unfolding of bitcoin. Spooking others and causing the turnaround that you saw in ODN.

Good analysis though and there's no such thing as a bad trade, just another learning experience!
