In the latest discussion on OpenCL technology, an issue was identified with MetaTrader 5's inability to employ GPU via OpenCL, specifically encountering an error coded 5114. This error hinders GPU selection for processes demanding elevated computation power. The built-in OpenCL support in MetaTrader 5, while detecting the GPU, fails to initialize consistent GPU usage. This persistent issue since 2013 affects a subset of MetaTrader users across various systems.

The initial workaround involves directly referencing GPU devices by ordinal number in MetaTrader's Journal tab, rather than using the intended flags for device selection. This makeshift solution sidesteps the error but is considered a temporary fix.

The proposed long-term solution involves a series of developmental phases, starting with a basic OpenCalibri test program that confirms feasible GPU usage, progressing through crea...

In the realm of automated trading, two distinct Expert Advisors (EAs) have been developed to leverage price movements across a moving average for entry signals. However, their operational nuances differentiate their strategic approaches.

The first EA adheres to a conventional trading pattern without employing a recovery strategy. Its configuration allows for fixed input parameters including Moving Average Period (MAPeriod), lot size, take profit points (TPPoints), and stop loss points (SLPoints).

Contrarily, the second EA incorporates a Martingale strategy to increase the investment after losses. This model adjusts not only the lot size but also the profit taking and loss stopping parameters based on predefined multipliers. The rising stakes are capped at a maximum lot size to mitigate potential risks.

Both systems integrate key functionalities from the 'ImportantFunctions.mqh' fi...

Angle-based operations have long been integral to trading strategies, particularly due to the simplicity and clarity of constructing angles. Gann tools are a prime example of utilizing angles for market analysis. This approach, while traditional, can still yield refreshing insights when revisited with modernized methodologies.

In practical terms, constructing an angle-based indicator involves setting up axes—typically price versus another currency price—to compare pairs and infer overbought or oversold states. Addressing discrepancies in axis values, such as different units like meters against kilograms, is crucial as it can skew the interpretation of angles. Standardizing these values to a common unit simplifies the calculation and enhances comparability.

Additionally, incorporating mathematical concepts such as wrapped normal distribution allows for handling infinite ranges in ang...
