Amwoga Khalwale Time Series Analysis is a statistical approach to studying and modeling data points collected sequentially over time. It’s used to understand patterns, trends, and behaviors in the data, and often to forecast future values based on those insights. Unlike random data sets, time series data has a natural temporal ordering—think stock prices, weather measurements, or … Read more
The Discrete Fourier Transform (DFT) is a version of the Fourier Transform specifically designed for finite, discrete data sets—like a sequence of numbers you might get from sampling a signal (e.g., audio recordings, stock prices, or sensor readings). Unlike the continuous Fourier Transform, which works with infinite, continuous functions, the DFT takes a fixed number … Read more
The Fourier Transform is a mathematical tool used to break down a function—typically a time-based signal—into its constituent frequencies. It transforms a signal from the time domain (where it’s expressed as amplitude over time) into the frequency domain (where it’s expressed as amplitude across different frequencies). This allows you to see the frequency components that … Read more
Drummond Geometry is a technical analysis trading method developed by Canadian trader Charles Drummond, beginning in the 1970s and evolving over decades. It focuses on identifying high-probability trading areas by establishing support and resistance zones across multiple time periods. The approach combines geometric patterns, short-term trend lines, and moving averages to predict market behavior and … Read more
Bitcoin is the original cryptocurrency, launched in 2009 as a decentralized digital currency, operating on blockchain technology. It’s widely recognized for its security, anonymity, and potential as both an investment and a medium of exchange, with a fixed supply cap of 21 million coins. Trump Coin, on the other hand, refers to various meme cryptocurrencies … Read more
The Fidelity Low Duration Bond Factor ETF (ticker symbol: FLDR ) is an exchange-traded fund (ETF) designed to provide exposure to a diversified portfolio of U.S. investment-grade bonds with relatively low duration, meaning they are less sensitive to interest rate fluctuations compared to longer-duration bonds. This makes the fund particularly attractive for investors seeking lower … Read more
Libertarianism and anarchism share some common ground in their skepticism towards state power, but they diverge significantly in their philosophies, goals, and methods: Libertarianism: Anarchism: Key Differences:
The Goertzel Algorithm is a digital signal processing (DSP) algorithm used to efficiently compute individual terms of the Discrete Fourier Transform (DFT), particularly when only a few frequency components are of interest. It is widely used in applications such as tone detection (e.g., DTMF tones in telecommunication) and other spectral analysis tasks. Applications The Goertzel … Read more
What Is Classical Economics? Classical economics school of thought flourished primarily in Britain in the late 18th and early-to-mid 19th century. Its main thinkers are held to be Adam smith, Jean-Baptiste Say, David Ricardo, Thomas Roberto Malthus and John Stuart Mill. The value and distribution theory of classical economics states that the value of a … Read more
Stock markets around the world have different trading hours, depending on your current geographic location. Stock market opening times vary in each country, depending on the local working hours and culture. Most stock markets around the world will be open for trading from Monday to Friday, and will be closed on the weekends. Some stock exchanges … Read more
