Atom made a leading diagonal for wave 1 or A, followed by a WXY correction for wave 2 or B. It can go bullish, corrective for an ABC or impulsive with a long 3rd wave. Now It bounced 0.854 fib support level. Stop lose below 21.40 at invalidation level. If you enter now it has a good risk reward 1:5 at least if it is a corrective move. Good luck!
