Break of the confirmed long term trend line; watching the retest and chop of the level. 50-EMA acting as support on the Daily, break below which would give strong confirmation of continued downtrend.
Overall the stock has bearish fundamentals and bearish momentum. I would not look for a reversal and push upwards. At best ZM might trade side-ways at this level.
Target 1 = $100
Target 2 = $75
