jj,
I've managed, I think, to reproduce your chart from permalink #973. It's a five minute chart, right?
Many pages ago on this thread, I recommended an enhancement to VSA in which volume would be broken down into volume up vs volume down. The "experts" on the thread didn't like my idea, but here's an example where it is valuable (in fact, invaluable). See attached chart. On your putative upthrust, the total volume is too high, but just as importantly, the upvolume nearly matches the downvolume (upvolume is seen as a green line inside the wider red line which is downvolume). This clearly shows that there was significant buying on this bar, hence it was not an upthrust. The total volume itself would have been a clue, but the picture is clearer if you separate the up from the down. |

Please correct me if I'm wrong, isn't the volume shown there just at bid or ask? Red if at bid or green if at ask? And if that's correct how reliable do you think it is to expect that an order at bid was a sale and at ask was a buy?
Thanks
