Structs offer a fundamental bridge between object-oriented and conventional programming. They simplify data management, yet demand careful handling, especially when passing values to functions or procedures. Historical constraints of languages like C have given way to safer data transfer mechanisms. Effective use involves minimizing the knowledge functions require about structures.

Understanding structures as special data types enriches programming flexibility. Global struct declarations allow smoother data transfer, a common practice in languages like Python and JavaScript. This aids in reducing function overloads, enhancing code efficiency. Employing structures in this way allows for clearer code organization, data encapsulation, and easier management of complex datasets. Proper implementation ensures a clean, efficient codebase ready for future expa...

An effective signal indicator for MetaTrader 5 combines RSI and Moving Average to identify trend-following signals. Designed as a clean visual tool, it aids manual trading or provides signals for Expert Advisors. The strategy draws arrows based on specific conditions. For a buy signal, a blue arrow appears when the closing price is outside the Moving Average, and the RSI value exceeds 50, indicating an uptrend with bullish momentum. For a sell signal, a red arrow is drawn when the closing price falls below the Moving Average, and the RSI is below 50, confirming a downtrend with bearish momentum.

Features include clean, commented code and customizable parameters for RSI and MA periods. The indicator utilizes standard MT5 buffers, making it ideal for iCustom() function use in Expert Advisors.

The Dynamic Gaussian Channel indicator constructs dynamic support and resistance levels by utilizing smoothed price data through a Gaussian filter. It consists of three main lines: resistance, median, and support. The algorithm applies Gaussian smoothing to the high and low prices to identify extrema over a specified period and creates a channel based on the smoothed values.

It offers customizable parameters, allowing users to adjust the calculation period and line colors/styles. During initialization, the Gaussian filter weights are calculated for smoothing. The smoothing process applies this filter to high and low prices. Resistance is determined by the maximum smoothed high, support by the minimum smoothed low, and the median by the average of these two.

Implementation uses indicator buffers, the Gaussian filter with a 5-bar window, and is opt...
