The ScaleChart provides a visual method of modify the scale prices. Use the lines and handles in the chart to set the Starting Price and bottom price and have TWS calculate the price increment.
To move the prices, grab a line in the chart.
When you move the blue Starting Price line, the other lines move in the same increment.
When you move the Bottom Price line, the Price Increment is recalculated since the distance between the starting and bottom prices have changed. If the Initial Component is higher than the Subsequent Component size, the Top Price is also recalculated.
If you move the top price, the Initial Component Size, Price Increment and Bottom Size are all recalculated.
