Scale Order Columns

Column Name

Description

Scale Orders

Scale Incr.

This amount is used to calculate the per-unit price of each component in the scale ladder. Note that the price increment cannot be negative.

Scale Init

Set the initial component size for the scaled order.

Scale Profit Offset

A value in this field instructs TWS to submit profit-taking orders, and defines the minimum amount of profitability you will accept to exit a position. ScaleTrader will submit an opposite-side profit order against the original order, using the limit price of the parent component plus/minus the profit offset. For example, if you submit a 10,000 share BUY limit order at $65.00 with a component size of 1000, and enter $15.00 as the Scale Profit Offset, as soon as the first component executes, TWSwill submit a 1000 share SELL limit order at $80.00.

Scale Sub

Set the subsequent component size for the scaled order. If you leave this field blank, ScaleTrader uses the initial component size.
