Order types can be specified in the "Update Trading System" form by updating the fields just above buy, sell, short and cover rules controls.
Example:
Buy using limit order at tomorrow (limit = close)
Here are the trading order types that are available in QuantShare:
Market at open
Market at close
Limit order
Stop order
Stop limit order
To change an order type using QL (QuantShare Language):
- Select "Create trading system using the formula editor" tab
- Type the next lines to associate a limit order to buy signals
SetSimTiming(_Buy, _Limit, 0);
BuyPrice(close * 0.99, 10);
The "SetSimTiming" function allows you to specify an order type to associate with a signal type. Here, we associate limit order type to buy signals. We set "0" in the third parameter to indicate that we want to execute the order tomorrow (signal date + 1).
The "BuyPrice" function allows you to specify the limit or/and stop price of an order. Here, we indicate that the limit price is 1% below the close price and that the order is valid for 10 days only. After this period, the order is automatically removed.
To get the list of available fields in a parameter, click on this parameter then use the CONTROL+SPACE shortcut.
