USDCAD - 4H - Next resistance coming up (Gartley/Butterfly)

I posted a similar idea a couple weeks back, anticipated the first retracement in this recent upmove that is the BC leg of the drawn in gartley(link below).

now we are coming into the next interesting area for this pair. this is a combination of a gartley and a butterfly that retests a prior decisionzone in the market(white box)
while both patterns are technically already active im still waiting. i wanna see the market just a little bit higher or wanna see confirmation by a break of the possible doubletop that is represented by the arch. either way, i should get into this trade.
if we go down from here and confirm the double top, then stops can go above the double top or the white box. if we go higher from here and i get filled on top, stops must go at least above the white box.

the 3 green lines represent prior decision zones in the market that can be use for targets.
