Weighted OBV by BB

Original from tradingview.com/u/JeroenHouttuin/ I just added BB

Cumulative Force Indicator. Can also be seen as an OBV indicator that takes the price differences into account. In a regular OBV, a high volume bar can make a huge difference, even if the price went up only 0.01, and it it goes down 0.01 instead, that volume makes the OBV go down big time, even though in both cases hardly anything really happened. cForce is a more realistic view on where the money is flowing.
