The power of correct volume analysis cannot be overlooked. Unfortunately the ability to read volume correctly is not readily discussed or freely available. Off-the-cuff remarks such as, “increased volume on advances is bullish and increased volume on declines is bearish” are bantered around but that’s as far as it goes. The correct use and application of volume can make for some quite startling insights into price action, especially when one is swing trading or leaning against support and resistance points or zones of confluence.
I set up my charts with a couple of extra volume measures. I use a normal volume histogram that can be found with almost all software packages. However, if there is a larger volume spike skewing the ability to read the volume properly I will edit the data accordingly. Next, I add a 10-day moving average of the volume.
