ZM is in the 1% of stocks that showed green today, in the worst market decline since 1987. If it can hold up in a market that tanked like this, then it can easily rally and rally hard on a relief bounce, which the market is due for. This is showing a rounding formation in the chart and in the volume. The volume went from decreasing to increasing following a same type of rounding formation. The 30 ema is right under the bottom of the formation as support. IF the bottom falls out of the rounding pattern and closes below the 30ema, the setup failed and will exit.
