There is a big difference between overbought and overpriced.
Traders concern themselves with overbought and investors concern themselves with overpriced (for sell decisions).
Tyhee running from $.45 to $.55, a 20% move can become slightly and temporarily overbought causing a pause or minor sell-off.
But take care, Tyhee can about double and not be overpriced based on current evaluation metrics.
