Hi Euan,
Thanks for posting your analysis here it is always interesting to see what others are looking at.
As for the wedge, while I can see where you are coming from I probably wouldn't focus on that particular pattern, even though technically I think you could say that is a wedge. My reasoning here is that it is not well defined enough yet.
One thing that I think you will find about technical analysis is that different people are going to have different opinions about the same chart, which is one of the good things about posting your charts here so you can here multiple people's opinions.
If I can give you a general piece of educational advice, the first step I think most successful traders take, before even thinking about a potential trade in an instrument, is to get a big picture overview of the market. They do this so they have an understanding of where the major levels are in the market that others are watching, so they can anticipate what the market is likely to do around those levels. As an example, lets say I was daytrading the EUR/USD and thinking about a short position off of a pattern that I see on the 5 minute chart. Although it may not show up on the 5 minute chart, there is a major trendline support level which is on the daily chart just below where the market is right now. So even though I am day trading and not picking trades off of a daily chart, it is still important to know what is going on in the longer term timeframes and what the major levels are that people are watching.
Once a trader understands this, then he or she can make trading decision with the full picture, instead of just one piece. There is a video below on this, which I encourage you to check out if you have not done so already.

Lastly, there is a thread below where we focus on the EUR/USD specifically, so if you would like to post any analysis or questions relating to the EUR/USD there in the future feel free to do so.
