Futures Order Stairs
Contents
FOS is designed to place orders on futures and options automatically and to make profit on price fluctuations in the specified range. The idea of FOS is to create a grid of bids and asks. When an order is filled, the system places an opposite order at the neighboring price.
To open the FOS Manager window, click the 
button.
Right-click on the desired stair to open a commands list, where you can:
- Open the stair settings window;
- Start FOS;
- Stop FOS; and
- Delete FOS.
Some commands might be unavailable. To activate them, open the settings window by double-clicking on the stair name.
General operations

Any number of order stairs can work on the same trading account, but on different strategies.
Select a strategy or enter a strategy name in the text field. If a strategy with the specified name does not exist in the selected account and portfolio, then it will be created.
Note that you cannot create one on actual strategy.

The new Order stairs will appear in the FOS list.
Start FOS
To start FOS you need, double-click on the stair’s name.

When an order is filled, the midmarket is set to the order price. An opposite order is placed at the previous midmarket. The fills generated by FOS are accumulated in the FOS strategy. A process of automatic trading is determined by the set of parameters (see FOS parameters).

button.
Delete FOS
To delete FOS, click the

FOS parameters
FOS is configured using the following parameters:
Midmarket – base price to place orders from. The Take market button sets the midmarket to current market price
Orders number– number of orders of each direction in the grid
Quantity – order size
Price step – step in the order grid
Upper stop price – upper price to stop FOS at
Lower stop price – lower price to stop FOS at
To deactivate Upper stop price / Lower stop price parameters you need to specify
0value.Slippage – order price offset to the best price. This parameter affects orders placed to close current position. The position is closed when FOS is stopped at any of the stop prices
Position – current position
When you enter parameters, an order stairs is created.
The scale shows the current price 
,
orders to buy 
and to sell 
,
and the stop price 
.
When an order is filled, the system places an opposite order at the neighboring price.
When the Upper/Lower stop price is reached, FOS will be stopped and the current position will be closed at the market price (with respect to the Slippage parameter). All the fills generated by close position order will be displayed in the FOS strategy.
