As a powerful, flexible and easy to use quantitative trading platform for the whole network, the FMZ Quant Trading Platform has very low barriers to use, and the robot program takes up few resources. But we still hope that the robot can start when it needs to run and stop when it doesn't need to run.
For example, the non-opening time accounts for the vast majority of the whole day when conducting program and quantitative trading of commodity futures. In this way, we do hope that the robot will only run at the opening time, and that it will only run at the opening time every day to save money. Isn't it exciting? To meet this requirement, we can use Python language to write a strategy robot running on the FMZ Quant Trading Platform, and let the robot control the start and stop of the robot at regular intervals through the extended API interface of the FMZ Quant Trading Platform.

If there is a need, let's do it!

In fact, the whole code is very simple. The example of calling the FMZ Quant Trading Platform extension API interface can be used directly.

Address: example

Use the function in the example directly: def api (method, *args)
The interface we need to call is also very simple. The following two interfaces are used (can be found in the FMZ document)

  • RestartRobot
    Restart the robot interface and pass in the parameters into the robot ID.
    Use specific id to call: api ('RestartRobot', id)
  • StopRobot
    To stop the robot interface, the parameters are also the robot ID.
    Robot ID:

To call the FMZ Quant Trading Platform extension API, you need to use the API KEY of the FMZ Quant Trading Platform.
You can generate your own API KEY in account management.
We pass in the API KEY as a strategy parameter.

The rest is to write timing logic, which is also very simple. Set timing parameters:

["175708,14:55:33-15:10:33", ...]

The ellipsis indicates that more settings like "175708,14:55:33-15:10:33" can be set.
The timing parameter is a JSON string, which will be parsed into a list in the strategy code. Each element in the list is a set of robot start/stop settings.


They are separated by commas. The part before the comma 175708 is the robot ID, and the part after the comma is the start time/stop time.
In the above example, the robot with ID 175708 starts at 14:55:33 and stops at 15:10:33.

Then, in the strategy, the robot will keeps rotating. Each round rotation will first obtain the current time, and then judge whether to trigger the start or stop of the robot according to the comparison between the current time and the timing time.
If triggered, call the api ('RestartRobot ', id) or api ('StopRobot', id) to start and stop the robot.

As an example, the FMZ Quant Trading Platform's extended API is still very powerful. It is no problem to build your own quantitative trading platform based on the FMZ platform with these extended APIs.
The timing robot is simple in design, it is to start at the time and stop at the time. It does not include mechanisms such as whether the startup is successful, inspection, exception retry, etc. If you are interested, you can add functions and expand them.
The strategy is for reference only.
