\\\"input\\\" field). Interactive commands are ultimately captured by the ```GetCommand()``` function. The difference is that it uses the ```\\\"group\\\"``` field for configuration. When clicking the button triggers an interaction, the dialog box that pops up on the page contains a **group** of configured input controls, allowing you to input a set of data at once.\\n\\nRegarding the ```\\\"group\\\"``` field in status bar button controls and group button control structures, note the following:\\n- The ```type``` attribute in group only supports the following 4 types, and the ```defValue``` attribute is the default value.\\n \\\"selected\\\": Dropdown control, use the ```|``` symbol to separate each option in the dropdown.\\n \\\"number\\\": Numeric input box control.\\n \\\"string\\\": String input box control.\\n \\\"boolean\\\": Checkbox control, checked is boolean true, unchecked is boolean false.\\n- Interactive input controls support dependency settings:\\n For example, in the following example: ```\\\"name\\\": \\\"tradePrice@orderType==1\\\"``` setting, this makes the **trade price** (```tradePrice```) input control only available when the **order type** (orderType) dropdown control is set to **limit order**.\\n- Interactive input control names support bilingual settings:\\n For example, in the following example: \\\"description\\\": \\\"下单方式|order type\\\" setting, use the ```|``` symbol to separate Chinese and English descriptions.\\n- Although the ```name``` and ```description``` fields in group have the same field names as those in the button structure, their definitions are different.\\n The ```name``` in group also has a different definition from the ```name``` in input.\\n- After a group button control is triggered, the format of the sent interactive content is: the button's cmd field value, and group field related data. For example, when testing the following example, the content output by the ```Log(\\\"cmd:\\\", cmd)``` statement:\\n ```cmd: open:{\\\"orderType\\\":1,\\\"tradePrice\\\":99,\\\"orderAmount\\\":\\\"99\\\",\\\"boolean\\\":true}```, which is the content returned by the ```GetCommand()``` function when an interactive operation occurs: ```open:{\\\"orderType\\\":1,\\\"tradePrice\\\":99,\\\"orderAmount\\\":\\\"99\\\",\\\"boolean\\\":true}```.\\n- The ```type``` attribute of button controls only supports: ```\\\"button\\\"```:\\n Button controls that support input data, i.e., controls with the ```input``` attribute set, the ```type``` attribute in the ```input``` field configuration supports multiple control types.\\n\\nRefer to the following example:\"}, {\"examples\": [{\"code\": \"function main() {\\n // The dropdown control in the page triggered by the status bar button control (implemented by setting the input field) testBtn1 button uses the options field to set options and the defValue field to set the default option.

On the FMZ platform, set the trading pair to ```HMSTR_USDT```, then use ```exchange.SetContractType(\\\"HMSTR-USDT-250207\\\")``` to set this contract.\\n For functions that support the ```symbol``` parameter, such as: ```exchange.GetTicker()```, ```exchange.CreateOrder()```, etc., you can specify the ```symbol``` parameter as: ```HMSTR_USDT.HMSTR-USDT-250207``` to get market data for this contract or execute orders.\\n- Futures_HuobiDM (Huobi Futures)\\n Set to current week contract: ```exchange.SetContractType(\\\"this_week\\\")```.\\n Set to next week contract: ```exchange.SetContractType(\\\"next_week\\\")```.\\n Set to quarterly contract: ```exchange.SetContractType(\\\"quarter\\\")```.\\n Set to next quarter contract: ```exchange.SetContractType(\\\"next_quarter\\\")```.\\n Set to perpetual contract: ```exchange.SetContractType(\\\"swap\\\")```.\\n Supports contracts with ```USDT``` as margin. Taking ```BTC``` contract as an example: use ```exchange.IO(\\\"currency\\\", \\\"BTC_USDT\\\")``` to switch to contracts with ```USDT``` as margin,\\n or directly set the current trading pair to ```BTC_USDT``` when configuring live trading parameters and adding exchange objects. After switching trading pairs, you need to call the ```exchange.SetContractType()``` function again to set the contract.\\n- Futures_BitMEX (BitMEX)\\n Set to perpetual contract: ```exchange.SetContractType(\\\"swap\\\")```.\\n Futures_BitMEX exchange's delivery contracts are monthly contracts, with contract codes as follows (January to December):\\n ```code\\n \\\"January\\\", \\\"February\\\", \\\"March\\\", \\\"April\\\", \\\"May\\\", \\\"June\\\", \\\"July\\\", \\\"August\\\", \\\"September\\\", \\\"October\\\", \\\"November\\\", \\\"December\\\"\\n ```\\n Set delivery contract: ```exchange.SetContractType(\\\"December\\\")```.
