This indicator improves upon the normal OBV indicator by including Moving Averages of OBV. Additionally clouds have been created between the MAs if desired as well as a selection of MAs and the choice of MA lengths for personal preference. Lastly it can also plot the lowest and highest values of OBV for x bars back so one can clearly see the movement of volume increasing or decreasing. For timing both price and volume, it is good to use the same MA lengths and type for both price and volume. This helps keep timing in sync and show a strong correlation between price and volume. Volume from Market Makers are the catalysts that drive the price up and down. Patience and timing are crucial for joining the volume created by the Market Makers.
If you are new to charting and technical indicators, pick up my Trade Archer - Moving Averages - v1 script as well. The defaults for both scripts have the same moving average type and lengths so timing is the same between Price and OBV moving averages.
