1)什么是Money Flow/Up Tick/Down Tick?
The volume of shares of a security that are traded when the price is increasing. Uptick volume is used in trading strategies based on trends, with the difference between uptick volume and downtick volume referred to as the money flow. Stocks with positive momentum will trade at an increasing uptick volume as current trading prices are above the average price.

2)Money flow可以理解为入场/出场资金(accumulation/distribution)
Let's break this down into a language that we can all understand. The first thing is to explain accumulation/distribution, which is the momentum indicator that determines money flow. Chaikin understood that if a stock closed above its midpoint for a given session, the stock exhibited accumulation that day. Conversely, distribution is the order of the day if the stock closed below its midpoint.

这个可以从WSJ网站上的数据直接算出来。
