EUR/JPY break and retest of countertrend trendline

Price has broken and retested the countertrend trendline, my bias was to stay long until the upper channel trendline and then see a potential fall to the downside, however I don't think this will happen.

I have closed my first long position in profit but left my recent trade open in a minor loss incase my first idea continues to play out.

I will be working on looking for a more valid target (TP) but for now my target is at the lower trendline of the original channel.
