Yes, it looks difficult. I don’t see striking s/r price levels on D1 either. There are symmetrical wedge boundary lines above and below the current range but the range itself has wide oscillations and even though this pattern might have set up from 26/08, we still might be only half-way to the apex. Whether these pattern boundaries will be s/r and whether that suits your strategy are two further questions.
But my view might be coloured by my categorisation of both of these two currencies as weak, with CHF somewhat the weaker. So why not seek a more opposed pair, like AUD/NZD or AUD/CHF? GBP would be a good base on paper but Election/Brexit newsflow makes TA for these pairs unreliable.
Also, why not substitute JPY for CHF as the counter?
