This dataset was created for research on blockchain anomaly and fraud detection. And donated to IEEE data port online community. The dataset contains transaction hashes of all bitcoin Heists, Thefts, Hacks, Scams, and Losses from BLK files.

Using this dataset one can create a directed acyclic graph DAG of bitcoin transaction network as mentioned in references. A directed-acyclic graph is created from the bitcoin transaction data and metadata is extracted to create this dataset.

This method prints a concise summary of the data frame, including the column names and their data types, the number of non-null values, the amount of memory used by the data frame. As shown above, the data sets do not contain null values but some of the columns where I expected numerical or float values, instead contain object Dtype like the 'market cap' column.

A simple moving average, also called a rolling or running average is formed by computing the average price of a security over a specific number of periods. Most moving averages are based on closing prices; for example, a 5-day simple moving average is the five-day sum of closing prices divided by five. As its name implies, a moving average is an average that moves. Old data is dropped as new data becomes available, causing the average to move along the time scale.

The example below shows a 5-day moving average evolving over three days. The first day of the moving average simply covers the last five days. The second day of the moving average drops the first data point 11 and adds the new data point So the simple moving average is the unweighted mean of the previous M data points. The selection of M sliding window depends on the amount of smoothing desired since increasing the value of M improves the smoothing at the expense of accuracy.

The moving average is used to analyze the time-series data by calculating averages of different subsets of the complete dataset. Since it involves taking the average of the dataset over time, it is also called a moving mean MM or rolling mean. Moving averages are widely used in finance to determine trends in the market and in environmental engineering to evaluate standards for environmental quality such as the concentration of pollutants. The easiest way to calculate the simple moving average is by using the pandas.

This method provides rolling windows over the data. On the resulting windows, we can perform calculations using a statistical function in this case the mean. The size of the window number of periods is specified in the argument window. The accuracy of this model depends largely on your choice of weighting factors.

If the time series pattern changes, you must also adapt the weighting factors. When creating a weighting group, you enter the weighting factors as percentages. The formula states that the value of the moving average S at time t is a mix between the value of raw signal x at time t and the previous value of the moving average itself i.

It is basically a value between the previous EMA and the current price The degree of mixing is controlled by the parameter a value between 0—1. Therefore, a day EMA will have a smoothing factor:. So the above Formulae can also be written as by simpley re-arranging the terms in the above formulae.

By looking at the documentation, we can note that the. This parameter adjusts the weights to account for the imbalance in the beginning periods if you need more detail, see the Exponentially weighted windows section in the pandas documentation. Exponential smoothing is a time series forecasting method for univariate data. Exponential smoothing forecasting is a weighted sum of past observations, but the model explicitly uses an exponentially decreasing weight for past observations.

Specifically, past observations are weighted with a geometrically decreasing ratio. The underlying idea of an exponential smoothing model is that, at each period, the model will learn a bit from the most recent demand observation and remember a bit of the last forecast it did. The smoothing parameter or learning rate alpha will determine how much importance is given to the most recent demand observation.

There are quite a few very popular strategies that Traders regularly executes based on Moving Averages. Lets checkout couple of them. And also the assumption that when a change in the long term behaviour of the asset occurs, the actual price timeseries will react faster than the EMA one.

Therefore, we will consider the crossing of the two as potential trading signals. When the price of an asset crosses the EMA timeseries of the same from below, we will close any existing short position and go long buy one unit of the asset. And when the price crosses the EMA timeseries from above, we will close any existing long position and go short sell one unit of the asset.

For some more of these strategies have a look at this article. Skip to content. Star 2. Permalink main.

Also, please drop me a line so I know that you found the data useful. The recordings are trimmed so that they have near minimal silence at the beginnings and ends. Download dataset. Sentiment :This dataset contains 16 lakhs tweets that are labelled as positive or negative with each class having 8 lakh tweets. This dataset was made by the students at Stanford. Their approach was unique because the training data was automatically created, as opposed to having humans manual annotate tweets.

This is described in their paper. Note: This dataset is not open-source. In case you use this dataset, please cite Sentiment as your source. Save my name, email, and website in this browser for the next time I comment.
