For both traders, the optimal course of action must be the same. Now this may sound simple, but human nature causes most people, when faced with a similar situation, to react differently. They tend to outthink the situation, figuring there must be some unique value that they alone can add to make it even better.
Dennis and Eckhardt demanded that the Turtles respond the same or they were out of the program and they did end up cutting people. You are not smarter than the market. So follow the rules. Hesitate and they would be toast in the zero-sum market game. Those were simply facts that everyone could see plain as day. Eckhardt was most interested in the last three questions, which addressed the equity level, the systems, and the risk aversion.
They were subjective questions all grounded in the present. It did not make a difference what the answers to these three questions were a month ago or last week.
Put another way, the Turtles could control only how much money they had now, how they decided to enter and exit a trade now, and how much to risk on each trade right now.
For example, if Google is trading at today, Google is trading at A trader who trades differentially because of swings in confidence is focusing on his or her own past rather than on current realities. How to handle profits properly is a separation point between winners and losers. Great traders adjust their trading to the money they have at any one time. Learn the exact rules used by Richard Dennis and his Turtles here :.

You can find the USB setup manual in the webshop right side menu. This may be an option for you if you want to use low Render values. You loose a bit of control but gain smoother paths. Set the number of subdivisions of the rendered paths the value is a power of 2. You should set this value carefully, because if you increase the render value by two you need four times more memory to render. Also the rendering is faster if you use low render values sometimes drastically.
But how low you can go with this value depends on the waviness of the hair the value is a power of 2. The objects that belong to a collection are instanced sequentially in the place of the particles. Only thusly registered shapes can be used by issuing the command shape shapename. Bind bye method to mouse clicks on the Screen. Set the size and position of the main window.
Default values of arguments are stored in the configuration dictionary and can be changed via a turtle. Canvas , a ScrolledCanvas or a TurtleScreen. Subclass of RawTurtle, has the same interface but draws on a default Screen object created automatically when needed for the first time. Provides screen oriented methods like setbg etc.
Subclass of TurtleScreen, with four methods added. Used by class Screen, which thus automatically provides a ScrolledCanvas as playground for the turtles. Data structure modeling shapes. None a compound shape has to be constructed using the addcomponent method. See Compound shapes. A two-dimensional vector class, used as a helper class for implementing turtle graphics. May be useful for turtle graphics programs too. Derived from tuple, so a vector is a tuple! The public methods of the Screen and Turtle classes are documented extensively via docstrings.
So these can be used as online-help via the Python help facilities:. Calling help on methods or functions displays the docstrings:. These modified docstrings are created automatically together with the function definitions that are derived from the methods at import time. There is a utility to create a dictionary the keys of which are the method names and the values of which are the docstrings of the public methods of the classes Screen and Turtle.
Create and write docstring-dictionary to a Python script with the given filename. This function has to be called explicitly it is not used by the turtle graphics classes. The docstring dictionary will be written to the Python script filename. It is intended to serve as a template for translation of the docstrings into different languages. If you or your students want to use turtle with online help in your native language, you have to translate the docstrings and save the resulting file as e.
If you have an appropriate entry in your turtle. At the time of this writing there are docstring dictionaries in German and in Italian. Requests please to glingl aon.
The built-in default configuration mimics the appearance and behaviour of the old turtle module in order to retain best possible compatibility with it. If you want to use a different configuration which better reflects the features of this module or which better fits to your needs, e.
The first four lines correspond to the arguments of the Screen. Line 5 and 6 correspond to the arguments of the method Screen. For more info try help shape. If you want to use no fillcolor i. If you set e. The entries exampleturtle and examplescreen define the names of these objects as they occur in the docstrings.
The transformation of method-docstrings to function-docstrings will delete these names from the docstrings. This will prevent exitonclick to enter the mainloop.
There can be a turtle. The latter will override the settings of the first one. You can study it as an example and see its effects when running the demos preferably not from within the demo-viewer. The turtledemo package includes a set of demo scripts.
These scripts can be run and viewed using the supplied demo viewer as follows:. The turtledemo package directory contains:. Multiple scripts demonstrating different features of the turtle module. Examples can be accessed via the Examples menu.
They can also be run standalone. A turtle. The methods Turtle. Methods with these names and functionality are now available only as methods of Screen. The functions derived from these remain available.
In fact already in Python 2. The method Turtle. A method Turtle. It returns a boolean value: True if a filling process is under way, False otherwise. This behaviour corresponds to a fill call without arguments in Python 2. Thus the full range of regular linear transforms is now available for transforming turtle shapes. The method Screen. Accordingly the latter has got an alias: Screen. So when working only with Screen and Turtle objects one must not additionally import mainloop anymore.
Two input methods has been added Screen. These popup input dialogs and return strings and numbers respectively. Navigation index modules next previous Python ». Turtle star Turtle can draw intricate shapes using programs that repeat simple moves.
