for new users of footprint (volume ladder) charts, some of the features may be a little overwhelming or difficult to understand. so hopefully a brief explanation will help. in most cases I used the original description from
market delta:
- delta
displays the cumulative (net)
delta for the entire bar. It is cumulative for the entire bar
- total volume
displays the total volume that occurred for each bar. It is cumulative for the entire bar
- unfinished auction
An “unfinished auction”, sometimes called “unfinished business”, is the term used to describe when the extreme price for a bar (either high, low, or both) has both buy AND sell volume
- poc
displays the highest volume at a specific price for this specific column
- min delta
displays the lowest overall delta value achieved for the entire bar. It is cumulative for the entire bar
- max delta
displays the highest overall delta value achieved for the entire bar. It is cumulative for the entire bar
- delta finish
This is the
pullback of delta from it's last high or low. If Delta last bounced off it's high before completing bar, the finish will be negative (or zero). If Delta last bounced off it's low before completing bar, the finish will be positive (or zero)
- cot high
cumulates the delta (ask volume minus
bid volume) in the bar tick after tick (trade
after trade). But it is reset to 0 on the tick which is either a higher high (within the bar) or a repeat of the former high of the bar
- cot low
cumulates the delta (ask volume minus bid volume) in the bar tick after tick (trade after trade). But it is reset to 0 on the tick which is either a lower low (within the bar) or a repeat of the former low of the bar
the cot calculations are a little different from the original
gom volume ladder. now we have a standardized definition, showing the same data on all platforms.
I tried to show/explain the cot from the original gom volume ladder here:
and here's how it looks like with the GomOrderFlowPro version:
