What Happens When Strong Uptrends Meet Bullish Sentiment?

Is there anything prettier than a consistently uptrending stock price chart? I'm drawn to these types of charts. I've always thought a consistent uptrend is an indication of strong buying power for a stock. However, while I can tell you if a chart looks like a consistent, methodical trend, it's hard to define it using data, which is necessary to create an indicator. That's why, until now, I've never put numbers behind my theory.
