Looks good o I have a slightly diff view. Above I have targets for W5 if GBP has the steam to get there
Nice Wolfe Wave not sure if you did the 1-3-5 2-4 lines for that reason but the target would be an alternate. If you are expecting the low to be hit then its a property of a wedge for price to retest the low of where it formed even though you call it some upward diagonal something or other...
See chart for my 2 cents.
