Trail of Intentions (TINT) is an RTX Extension indicator designed to display historical snapshots of the depth of market. TINT provides a wealth of options to visually identify relative size and changes in sizes among prices within same snapshot or from snapshot to snapshot over time. Users may customize the shading of the background of each price to reflect size or change in size of each price. Optional text may be displayed at each price showing size, change in size, size inside, or size outside (sum of size at or outside any given price). Key prices such as Ask, Bid, Last, and Average (size-weighted average) may be highlighted within each snapshot. Snapshots may be taken at a variety of rates driven by periodicity (Every Bar), trades (Every X Trades), time (Every X Seconds), and volume (Every X Volume). Snapshots may overlay bars, or be positioned on the right or left edge of the chart and users have the option to limit the number of snapshots displayed.
