Try strong increase in volume during up-move and strong increase in volume during down-move, also known as strong accumulation and strong distribution. To spot mathematically you may use VO (Volume Oscillator), PVO (Percentage Volume Oscillator) and or MVO (Market volume oscillator). The last one differentiate bullish and bearish volume surges.
