Definition of, and how to attach a bracket to an order.

1. Total Order Size (TOS) – the total number of shares the trader is willing to purchase (sell) as the price falls (increases);
2. Initial Component Size (ICS) – the number of shares to be purchased (sold) at the Starting Price;
3. Subsequent Component Size (SCS) – the additional number of shares to be purchased (sold) at each Price Increment (at successively lower prices in the case of a purchase and higher in the case of a sale). If a SCS is not entered, the ICS will be used for all component orders.
4. Starting Price (SP) – the price at which you are willing to purchase (sell) the Initial Component Size
5. Price Increment (PI) – in the case of a purchase (sale), this is the decrease (increase) in price at which each successive component order is to be executed.

1. TP = (((ICS/SCS) -1) * PI) + SP
2. BP = SP – (((TOS - ICS)/SCS) * PI

1. TOS = 4,000;
2. ICS = 1,000;
3. SCS = 500;
4. SP = $20.00
5. PI = $0.05

1. Profit taking orders – the Scale Trader may be set to send an offsetting order to take advantage of periodic price surges or if the trader has reached a specified profit objective. This feature may be enabled by checking the box titled “Create profit taking order” and specifying the Profit Offset. Using the example above and a Profit Offset of $1.00, once the ICS was filled at $20.00 and an SCS submitted at $19.95, two profit orders would also be submitted, one for 500 shares at $21.00 and another for 500 shares at $21.05. It should be noted that profit orders are scaled to the SCS regardless of the size of the ICS and that if the ICS > SCS then the profit order price is determined using the PI along with the Profit Offset. 
2. Restore size after taking profit – if using the profit taking orders feature, the trader can enable the repurchase of shares sold at a profit at the price they were originally bought at by checking the box titled “Restore size after taking profit”. This feature remains active whenever the price is within the range of TP + Profit Offset and BP. Using the example above, if order to sell 500 shares at $21.00 was executed this fill quantity would be put back into the original order at $20.00 and the order submitted at $19.95 would be cancelled.
3. Restart Scale Trader & Restart Scale Trader with Filled Component Size – these features allow traders using the profit taking order and restore size features to restart the algorithm if stopped, helping to resume the order starting from the point at which the scaled sequence left off.
4. Auto Price Adjustment – selecting this check box allows for an increase or decrease in the starting price automatically at stated time intervals (e.g., increase $0.01 every hour)
5. Scale Trader Page – provides a view of the real-time status of scale orders, including filled and total quantity, filled, remaining, and total value, and the percent filled for each scale. Accessible via the Page and then Create Scale Trader Page menu options.
6. View Scale Progress - right-click on the scale order line and select View Scale Progress. This will open a window displaying the complete scale price ladder, the Open/Filled component list for the parent scale order, and the Open/Filled component list for the child profit orders.

1. Products – any product offered by IB other than mutual funds (e.g., stocks, options, ETFs, bonds, futures, Forex);
2. Order Type - limit or relative (relative not offered for combination orders)
3. Time in Force – Day, Good-til-Cancel or Day-til-Cancel. May also specify if order is allowed to be filled outside of regular trading hours, if executions may be routed and executed during pre-open session and whether to ignore opening auction.
