Interactive Lot Sizing from a Chart Price Line
Summary
LotLine is a chart utility that displays a horizontal price line and calculates the trade volume, expressed in lots, needed to move a position to the price represented by that line. The user can drag the line to a different chart level, and the displayed required lot size updates accordingly. This makes the relationship between a chosen price level and position volume visible while adjusting the chart.
The description does not explain the calculation, specify which account or instrument properties it uses, or distinguish between different trade directions or order types. It also provides no examples, risk limits, or evidence that the displayed size controls exposure appropriately. The tool is therefore presented as a sizing aid rather than a full position-management method; users would need to understand its assumptions and verify how it handles contract specifications and account settings before applying its output.
Key ideas
- The script places a movable horizontal line on a price chart.
- It displays the lot volume needed to move a position to the selected line level.
- Dragging the line causes the displayed lot size to update.
- The description does not disclose calculation assumptions or risk controls, so the output needs contextual verification.
