Part 1: A Better OBV
In the classical OBV (On-Balance Volume) indicator, it simply takes the idea from traditional tape reading - treat the "up tick" as Buy, "down tick" as Sell, and it assumes no change in price as neutral* (*which is not the case in tape reading).
When it comes to interpret the daily volume as such, errors will add up cumulatively. For example, there are days when a Doji Star with high volume just merely one cent higher than yesterday price and the whole day volume would be taken as a BUY Volume....
Here is a gentlemen, William C. Garrett, attempted to break down the daily volume into two parts in his book - "Torque Analysis of Stock Market Cycle". And, I think it makes sense.

William showed his method in Fig. 4.3 in his book, and we can derive the formula from it as ...
