What is the docker?

The docker is a program that runs on your own Internet Server, which in charge of the data request, data reception, network link, Log review etc.You can treat it like your strategy’s executor. Even if the FMZ server offline (breakdown, etc.),it will have no influence on your robot that is running.The Manager can run on variety of operating system.Such as Windows, Linux, Mac OS, Android, Raspbian, etc.

What is backtest system? What it uses for?

When you completed a quantitative strategy, how do you know that the logic, amount and direction of profit of this strategy goes? Does it work? Apparently, we wouldn’t use the real money to test our strategies on the real market. But we could use the historical data to test it, see how it works out on the time, profit, and asset management in the past. It is winning or losing? How to use the Backtest System?

Does the number from the backtest system accurate? The results can be trusted?

FMZ divides the backtest system into real market level and simulation level.The real market level contains the whole completed historical data back testing.

The simulation level contains the k-lines data at regular intervals.Both level are based on the real market historical data. Only the real market level is more accurate and the results are more reliable.

The simulation level Backtest System explanation.

Notice that backtesting is the strategy only preform in the past. Historical data doesn’t represent the future. History may replay, it also may lead to the black swan. Please treat the backtest results reasonable and objectively.

If you are new to trading, you need to understand a few basic concepts:

1.3.1 A quick look of the main page¶

After learning the most basic concepts, let’s start using FMZ to explore the quantitative world.(Building your own quantitative trading system is a very large project, you need to have considerable computer knowledge and skills, fortunately, FMZ has done this for you!)

Register your FMZ account,Log in to https://www.fmz.com.

First time to log in the website, it looks like this:

  • 1.Your main control page
  • 2.Manage all your bots (start,stop,delete,open,etc)
  • 3.Manage all your strategies’ code
  • 4.Deploy and manage your docker

  • 19.Your account information.

1.3.2 Deploy the docker¶

First of all, FMZ’s framework is very advanced,the user’s robot program (that is, the automated trading program) is running on the user’s own computer (of course, it can also be run on the cloud server),So, it’s very safe (don’t need worry about the FMZ website breakdown etc.), the user has direct control over the program.

Docker is a program that run your robots and communicate with FMZ website. You need to run a Docker first before start a real market robot.

Note

It is highly recommended to use the cloud server for runing program stably, such as Amazon or Google Cloud Server.

In the Dashboard page–Adddocker button, you can link to the download page https://www.fmz.com/m/add-node.

Here are steps to deploy the dockr in a Linux server(centOS 6):

  • Buy a cloud server (VPS) from Amazon or Google, the lowest and cheapest configuration is enough. you may often has a free try for a long time.
  • Login your server, fellow the instruction from your server provider or Google.
  • Chose the docker that statisty your system version, most of the time, it is 64Bit.
  • For centos, run wget'http://q.fmz.net/dist/robot_linux_amd64.tar.gz', command not found? install first yuminstallwget-y.
  • Run tar-xzvfrobot_linux_amd64.tar.gz to unzip.
  • Run ./robot-srpcs@node.fmz.com:9902/xxxxxx-pyourFMZpassword,you should see something like 2018/07/0505:04:10LoginOK,SID:62086,PID:7226,Name:host.localdomain, which means everything is worked.
  • rpcs@node.fmz.com:9902/xxxxxx is unique to every users, find your own on https://www.fmz.com/m/add-node.
  • Now the docker isn’t run in the background, if you close the SHH client, the docker will stop.
  • Press ctrl+C to stop the docker.
  • Run nohup./robot-srpcs@node.fmz.com:9902/xxxxxx-pyourFMZpassword& to run in the background. this step can also be done by Screen command.
  • Check on https://www.fmz.com/m/dashboard, if everything is OK , you can find the docker deployed.

Steps to update the docker:

Note

If you want to keep the old docker, one server can run many dockers, just create a new folder and repeate the deploy steps.

Mac
  • Stop all robots that run on the docker.
  • Delete the docker from FMZ website. the docker will stop on your server too(don’t have to, you can run two dockers on one server, just create a new folder)
  • Run rm-rfrobot_linux_amd64.tar.gz in your dokcer files to delete the old docker.
  • Run wgethttp://q.fmz.net/dist/robot_linux_amd64.tar.gz to download the lastest docker.
  • Repeate the steps above.
  • Change robot’s config to use the new docker, restart robots.

Note

One docker can run many robots, however, you can deploy more than one dockers on different server for speed or request-rate-limit consideration.the docker can be specified or auto-distributed when start a robot.

Warning

There are two public dockers for testing. don’t use them to run your robot on real market.

1.3.3 Add exchanges¶

Add your exchanges at this page: https://www.fmz.com/m/add-platform.

Now support:

AccessKey and SecretKey is needed, you should apply on your exchange first.

Once the exchange is added, you can find it on Dashboard https://www.fmz.com/m/dashboard.

Note

New exchange supported is keep being added. you need to update the lastest docker to support new exchange.

1.3.4 Write or copy a strategy¶

Note

There are lots of details this docs doesn’t cover, you can explore by yourself, most of them are simple and clear.You can always post on our forum if you have any question.

Write your own strategy by clicking AddStrategy.

You can choose different code languages and backtesting

For beginners, copy this strategy to begain: https://www.fmz.com/strategy/103070, which can be found on https://www.fmz.com/square.

Some of the most common waveforms needed in simulating voltage and current sources are sine, square, triangular and sawtooth shapes.

LTspice® simulation software has a built-in pulse, sine, exponential, single frequency FM and an arbitrary piece-wise linear functions available in the source component editor. Although it may not look like it, LTspice does have a triangular and sawtooth functions available but they need to be created from either a PULSE or PWL function.

PULSE Function

PULSE fuction is often used in transient circuit simulation where we want the source to behave like a square wave. You can omit Ncycles if you need a free-running square waveform.

PULSE(Voff Von Tdelay Trise Tfall Ton Tperiod Ncycles)

A simple approach to creating a triangular and sawtooth waveform is using the PULSE fuction using the source component editor shown above. For the triangular waveform you can set the rise and fall time equal to 1/2 of your desired period in your pulse function. Likewise, to create a sawtooth fuction you cab set the rise time equal to the period and the fall time to zero. The PULSE function can be further modify to best match your simulation needs. Waveforms for these two fuctions are show on the top of the page.

PWL Function

For any arbitrary or complex waveform, you can always rely on the piece-wise linear function. The arbitrary piece-wise linear fuction is defined by a sequence of time and voltage pairs.

PWL(t1 v1 t2 v2 t3 v3...)

This specifies that for time before t1, the voltage is v1. For times between t1 and t2, the voltage varies linearly between v1 and v2. There can be any number of time, voltage points given and for times after the last time, the voltage is the last voltage.

To implement a triangular or sawtooth waveform you could use the following piece-wise linear functions. Waveforms for these two fuctions are show on the top of the page.

These two examples use an undocumented repeat feature of PWL function. To explore these features you will need to directly edit by right-clicking on the source symbol's text in the schematic editor rather than using the source component editor.

Here are some highlights of the undocumented features for the PWL fuction:

  • Repeat date pairs forever

PWL REPEAT FOREVER (0 0 .5 1 1 0) ENDREPEAT

  • Repeat data pairs for 5 cycles

PWL REPEAT 5 (0 0 .5 1 1 0) ENDREPEAT

  • A trigger expression that turns the source on as long as the expression is true

PWL (0 0 .5 1 1 0) TRIGGER V(node)>1

  • Scaled the time or source values

PWL TIME_SCALE_FACTOR=0.5 VALUE_SCALE_FACTOR=2 (0 0 .5 1 1 0)

More information on the pulse, sine, exponential, single frequency FM and an arbitrary piece-wise linear functions is available in the LTspice help file (F1). An example LTspice simulation is also provided below for your reference.
