Minor uptrend (and possible reversal)

I think the price moviment can have little uptrend in the 15 minutes chart (green line). I think that next week this short uptrend will reach another lower high and so it will touch the major downtrend line. I will expect a huge sell if this analisys is correct as suggested by the red arrow pointing at 35pence price target and then a major trend reversal on that 35pence price target.
(Im not an expert and Im not a professionist so i will not assume any responsability of any use of this analisys and this is not an investment advise, I said that becouse it is my first chart analisys ever and I just started studing)
