Wait for retracing to 84-82 then go buy

FX:CADJPY   Canadian Dollar / Japanese Yen
Spot an impulse wave for NZD/JPY.
Bullish convergence confirms III has formed which is 161.8% of I.
Now I'm expecting IV retracing lower than 84.461 but not past 82.020. (I territory) to satisfy Elliott's rule.
Would go buy around 84-82
