Markets are a function of time. When watching them, end users must be positioned at one particular point in time. The system currently allows users
|
|
to position themselves at any time they like.
|
|
|
|
In the future, it will be usefull to explore markets and compare them at different times simultaneously. Anticipating that future this module exists.
|
|
All the timelineCharts that depand on a datetime are children of this object Time Machine. In the future we will allow users to have more than one Time Machine,
|
|
each one with it own timelineCharts, and each one positioned at an especific point in titme.
