Video Walkthrough:

Configuration​

screenshot

The dropdown "Footprint Bar Type" allows selection among bar types. Settings below adjust based on the chosen bar configuration.

Time Interval Type​

"Time Interval" provides time-based bars. A new bar forms at each set interval, ranging from 30 seconds to 30 minutes.

For example, a setting of 30 seconds will overlay a footprint bar every half a minute:

Reversal Type​

Reversal Bar forms a new bar when the price reverses a set number of ticks from its extremes. A small green/red icon on the timeline marks the price for the new bar. You can select the tick count to trigger a new bar formation (a positive round number).

On the heatmap, the configuration above displays like this:

Range Type​

Range Bar sets a defined range, and a new bar forms if the price move exceeds this range. You need to specify the bar's range in ticks (a positive round number).

A 10-tick range bar is shown below:

Volume Type​

Volume Bar is based on a set traded volume. Once the volume surpasses this set limit, a new bar is created. You must define the volume for a new bar in a positive round number.

Here is an example of the above configuration:

Other Settings​

The width of each bar (or footprint column) is adjustable, catering to personal visual preferences. Moreover, if the type permits, alignment can be chosen as either left or right. A delta bar with a 160 width is shown below.

A variety of background and foreground styles are offered by the indicator. The options are:

  • None
  • Histogram (based on sum volume)
  • Histogram Delta +- (based on delta volume with coloured bars)
  • Histogram Diagonal Delta +- (based on diagonal delta volume with 2 sided coloured bars)
  • Histogram BS (buy / sell volume with 2 sided coloured bars)
  • Full Background Single Colour (single colour background for visibility)
  • Full Background Delta +- (background based on delta volume with +- colour).

The background positive and negative colours can be configured freely, their transparency can be configured numerically and shades can be used instead of single colours to indicate weight. If the background type is a histogram type, it can also be left or right aligned.

AutoScaling​

The Vertical Smart Scaling feature supports tick aggregation for all Footprint bar type. When the vertical scale is zoomed (the price axis), the Footprint automatically changes the tick aggregation and merges the price level together for better visibility.

In case of "Time Interval"; Footprint bar type, even horizontal (time axis), autoscaling can be used. If enabled, the Footprint Interval changes automatically to an Interval that can be displayed on the screen. (ex.: when zoomed out, 30 minutes footprints will be displayed, when zoomed in, 30 seconds)

Bar Statistics​

Bar statistics can be displayed for the bottom of the chart. Not only to enable or disable the statistics and their legends, but it allows you to pick one by one which statistics should be displayed and the Offset of the statistic bars from the bottom of the chart:

The statistics display:

Max Delta: The maximum delta of the bid and ask volume of the bar

Delta: The current difference of the bid and ask volume

Pullback Delta: The difference of the delta from the last extreme delta (retracement from the most recent max delta or min delta)

Min Delta: The Minimum delta of the bid and ask volume

Bar Height: The bar height in ticks

Sum Bid Volume: The sum of the bid volume

Sum Ask Volume: The sum of the ask volume

Sum Volume: The total volume

Sum Bid Trades: Sum of the bid trades

Sum Ask Trades: Sum of the ask trades

Sum Trade: Sum of all trades

For the Footprint text, you have options such as:

  • BxS (buy / sell volume with and x in between)
  • Sum (sum volume)
  • Horizontal Delta
  • Diagonal delta.

Note: The background and foreground information are decoupled and can give you a double view on the volume.The text colour can be chosen separately for positive and negative numbers and the text can be hidden. If the type allows, it can be right aligned too.

Note: The Footprint text size auto scales and as soon as the font size falls below 7, it is not displayed anymore.You can even choose the tickbox not to display texts.

Here's another configuration for reference:

Crypto markets can deliver different fraction formats, therefore prices might not be usable for building a footprint. The plugin offers a rounding feature for crypto markets to circumvent this problem:

FAQ​

Why can’t I see the Footprint when I pause in replay mode?​

For performance reasons, Footprint draws only when a replay is playing.
