This custom MQL5 indicator is designed to enhance trading strategies by detecting and visualizing divergences between price action and the Awesome Oscillator (AO). Divergences, often signaling potential market reversals or continuations, occur when price movements diverge from oscillator movements. This indicator incorporates several features to aid traders.

Key features include the detection of bullish and bearish divergences, identified by discrepancies between price and AO trends, such as price forming lower lows versus AO forming higher lows, or price achieving higher highs with AO forming lower highs. It visualizes these divergences on the chart using buy/sell arrows and trendlines, alongside a histogram displaying AO values.

The indicator utilizes buffers to store key data, ensuring that buy/sell signals, AO values, and aligned points for diver...

Directional Diffusion Models (DDMs) offer an innovative approach to graph representation learning by addressing the limitations of traditional diffusion models that rely on isotropic noise. DDMs incorporate data-dependent, directional noise, which slows down the signal-to-noise ratio decay, preserving crucial anisotropic structures. This leads to better feature extraction for downstream tasks like graph classification. The technique is particularly promising for financial market analysis, where asymmetric and directional patterns are prevalent. Implementing DDMs involves adding directional noise, using a novel kernel in OpenCL, and integrating it with MQL5 for practical application. The framework enhances MetaTrader 5 by facilitating the analysis of market trends and dependencies effectively.

The library in question is designed for efficient decompression of GZIP archives, useful for both *.gz files and HTTP responses compressed using GZIP. Robustly tested on files containing up to 0.5 GB of text. It can automatically determine compression type by examining the fourth-byte flag, distinguishing between a compressed file and data from a site without filename metadata. Decompression expects data input in a char array format.

The primary function for decompression is CryptDecode(CRYPT_ARCH_ZIP, tmp, key, tx). It integrates a GZIP class for initial checks to confirm if data is GZIP compressed through its first three characters. Upon verification, one might choose from various unGZIP method overloads aimed at optimizing speed and memory usage. The decompressed data fills the char array tx, facilitating immediate processing by parsers like CSV o...
