Bitcoin easy definition dictionary

Bitcoin is a decentralized digital currency created in January It follows the ideas set out in a white paper by the mysterious and pseudonymous Satoshi Nakamoto. The identity of the person or persons who created the technology is still a mystery. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms do, and unlike government-issued currencies, it is operated by a decentralized authority. Bitcoin is known as a type of cryptocurrency because it uses cryptography to keep it secure. There are no physical bitcoins, only balances kept on a public ledger that everyone has transparent access to although each record is encrypted.

Jump to navigation. Cheat sheet: Python 3. There are a lot of commercial solutions available, but I wanted an open source option, so I created the crypto-trading bot Pythonic. As I wrote in an introductory article last year, "Pythonic is a graphical programming tool that makes it easy for users to create Python applications using ready-made function modules. This hands-on tutorial teaches you how to get started with Pythonic for automated trading.

It uses the example of trading Tron against Bitcoin on the Binance exchange platform. I choose these coins because of their volatility against each other, rather than any personal preference. The bot will make decisions based on exponential moving averages EMAs. The EMA indicator is, in general, a weighted moving average that gives more weight to recent price data.

Although a moving average may be a simple indicator, I've had good experiences using it. The purple line in the chart above shows an EMA indicator meaning the last 25 values were taken into account. If the pitch exceeds a certain value, it signals rising prices, and the bot will place a buy order. If the pitch falls below a certain value, the bot will place a sell order.

The pitch will be the main indicator for making decisions about trading. For this tutorial, it will be called the trade factor.

For a crypto trading bot to make good decisions, it's essential to get open-high-low-close OHLC data for your asset in a reliable way. You can use Pythonic's built-in elements and extend them with your own logic. This workflow may be a bit overkill, but it makes this solution very robust against downtime and disconnections. The output of this element is a Pandas DataFrame. You can access the DataFrame with the input variable in the Basic Operation element. Here, the Basic Operation element is set up to use Vim as the default code editor.

First, check whether the input is the DataFrame type. If it is present, then open it, concatenate new rows the code in the try section , and drop overlapping duplicates.

If the file doesn't exist, trigger an exception and execute the code in the except section, creating a new file. As long as the checkbox log output is enabled, you can follow the logging with the command-line tool tail :.

For development purposes, skip the synchronization with Binance time and regular scheduling for now. This will be implemented below. The next step is to handle the evaluation logic in a separate grid; therefore, you have to pass over the DataFrame from Grid 1 to the first element of Grid 2 with the help of the Return element. When you run the whole setup and activate the debug output of the Technical Analysis element, you will realize that the values of the EMA column all seem to be the same.

This is because the EMA values in the debug output include just six decimal places, even though the output retains the full precision of an 8-byte float value. Developing the evaluation logic inside Juypter Notebook enables you to access the code in a more direct way. To load the DataFrame, you need the following lines:. You can access the latest EMA values by using iloc and the column name.

This keeps all of the decimal places. You already know how to get the latest value. The last line of the example above shows only the value. To copy the value to a separate variable, you have to access it with the. As you can see in the code above, I chose 0. But how do I know if 0. Actually, this factor is really bad, so instead, you can brute-force the best-performing trade factor. So extend the logic to brute-force the best performing values. This has 81 loops to process 9x9 , which takes a couple of minutes on my machine a Core i7 QM.

Sort the list by profit in descending order. When I wrote this in March , the prices were not volatile enough to present more promising results. I got much better results in February, but even then, the best-performing trading factors were also around 0.

Start a new grid now to maintain clarity. In Grid 3, add a Basic Operation element to execute the evaluation logic. Here is the code of that element:. The element outputs a 1 if you should buy or a -1 if you should sell. An output of 0 means there's nothing to do right now. Use a Branch element to control the execution path.

Due to the fact that both 0 and -1 are processed the same way, you need an additional Branch element on the right-most execution path to decide whether or not you should sell. Since you cannot buy twice, you must keep a persistent variable between the cycles that indicates whether you have already bought.

You can do this with a Stack element. The Stack element is, as the name suggests, a representation of a file-based stack that can be filled with any Python data type. You need to define that the stack contains only one Boolean element, which determines if you bought True or not False. As a consequence, you have to preset the stack with one False.

You can set this up, for example, in Grid 4 by simply passing a False to the stack. Forward a False variable to the subsequent Stack element. In the Stack element configuration, set Do this with input to Nothing. Otherwise, the Boolean value will be overwritten by a 1 or 0. This configuration ensures that only one value is ever saved in the stack True or False , and only one value can ever be read for clarity.

Right after the Stack element, you need an additional Branch element to evaluate the stack value before you place the Binance Order elements. Append the Binance Order element to the True path of the Branch element. The workflow on Grid 3 should now look like this:. For the purposes of this tutorial, I am demonstrating the overall process by using a Market Order. Because of that, I recommend using at least a Limit order.

The subsequent element is not triggered if the order was not executed properly e. Therefore, you can assume that if the subsequent element is triggered, the order was placed. This behavior makes subsequent steps more comfortable: You can always assume that as long the output is proper, the order was placed.

Therefore, you can append a Basic Operation element that simply writes the output to True and writes this value on the stack to indicate whether the order was placed or not.

If something went wrong, you can find the details in the logging message if logging is enabled. For regular scheduling and synchronization, prepend the entire workflow in Grid 1 with the Binance Scheduler element. The Binance Scheduler element executes only once, so split the execution path on the end of Grid 1 and force it to re-synchronize itself by passing the output back to the Binance Scheduler element.

If you want to take advantage of these low-cost clouds, you can use PythonicDaemon, which runs completely inside the terminal.

PythonicDaemon is part of the basic installation. To use it, save your complete workflow, transfer it to the remote running system e. As I wrote at the beginning, this tutorial is just a starting point into automated trading. When it comes to letting your bot trade with your money, you will definitely think thrice about the code you program. So I advise you to keep your code as simple and easy to understand as you can.

You can download the whole example on GitHub. Thanks for quite well-developed piece, Stephan. It was very resourceful for me. How to automate your cryptocurrency trades with Python Opensource.
