The fractal indicator requires a specific number of bars to determine a fractal formation. Typically, a total of five bars are analyzed, where the middle one is the extremum being evaluated—either a potential high or low. When customizing fractal indicators, the distance between the price and the fractal arrows can be adjusted through input parameters, offering flexibility according to user requirements.

Customization options extend to the use of Wingdings characters for arrows, allowing users to select preferred symbols. Arrow size is another customizable feature, easily adjustable via input parameters to enhance visibility and effectiveness on charts.

The underlying principle is to identify local high highs (hh) or low lows (ll), which can indicate potential market direction changes when the fractal is broken. These features allow for more organize...

The Commodity Channel Index (CCI), developed by Donald Lambert in 1980, has become a staple for traders, particularly within MetaTrader platforms. This indicator calculates price deviation from the mean relative to the mean absolute deviation, where the traditional correction factor is set at 0.015.

Advancements in computation allow the use of standard deviation for a more accurate indicator calculation. A classical CCI recommends a period of 14 samples. When periods are shorter, robust statistical methods are valuable for reliable parameter estimates.

Implementing Theil-Sen estimations, robust methods produce stable results. Variants of CCI—classical, using standard deviation, and robust—show differences in market performance. These insights provide utility for trend estimation in trading strategies.

Static variables in MQL5 present a powerful yet challenging concept for programmers, addressing global variable management issues. Unlike Python, MQL5 allows variables to retain values across function calls, enhancing control within code blocks. Static variables avoid inadvertent value loss, crucial in maintaining algorithmic consistency. However, misuse can lead to unexpected outcomes, like turning factorial calculations into power-of-two results. Careful initialization and understanding of lifetime are key. Embracing static variables empowers developers to streamline code without compromising control, benefiting both algorithmic trading efficiency and code integrity in the MetaTrader 5 environment. Understanding these concepts elevates programming precision in financial trading systems.

The Negative Volume Index (NVI) is a technical analysis tool for MT4 and MT5 that relies on tick volume, with MT5 also supporting real volume. Developed in the early 20th century and refined in 1976, the NVI functions by adjusting only when the current bar’s volume is less than the previous bar's. Its design includes a solitary oscillating line visible in a distinct chart window, independent of other indicators.

MTF support allows users to display data across different timeframes. It can be switched to display the Positive Volume Index (PVI), highlighting price changes tied to increased volume. However, PVI is often seen as less informative.

The NVI's classical strategy involves confirming trends by observing the NVI's movements, acknowledging susceptibility to false signals similar to other MA crossover strategies. Divergence between price moveme...
