Glad to read your emphasis on the importance of ‘Relative Volume’ in determining how trustworthy market moves really are.

It’s the bedrock of much of our analysis at Trade-Ideas as you know. We express the concept as a ratio, placing the current accumulated volume up to any given point in the day over the historical average volume of the same period. A reading such as 1.5 means therefore that a particular issue is 50% above its normal volume. A reading of 7 means its trading 7x more than usual; and so on for readings of 0.6, etc.

Full definition of Relative (aka Current) Volume.
