93% of shares traded 25% lower at .0015. That makes you 93% wrong and 7% right.
Ignoring that ZENG is thinly traded, with only a few trades per day, is a foolish way to track trading. Use a moving average to track average over several trades, a volume average, or a dollar average. These measures better fit a penny stock like ZENG.
The charts produced better lend themselves to TA than skewed "last trade" or painted charts.
