$SOON Down 6.4% in 15 minutes, trading at 0.3214, with a 24h range of 0.2995 ~ 0.3463.
A valid breakout is usually accompanied by increased volume, while a false breakout often lacks volume. This is the method I use most often to assess them.
The selling pressure came in a concentrated wave. Whether it continues will be clear from the volume over the next few candlesticks.
