An advanced indicator offers key configuration features for precise candle analysis. Users can define the SelectedWeek parameter to specify which week's candles are numbered. When set to 0, all candles are included, while a non-zero value limits it to the chosen week. The NumberFirstCandle option dictates whether numbering begins at the day's first or last candle. Dynamic filtering ensures only candles from the designated week are evaluated. Text positioning is adaptive, placing numbers above bullish candles and below bearish ones, with spacing adjusted via the PriceOffsetFactor. Visual elements like color, font, text size, and anchor type can be tailored for clarity. The indicator maintains efficiency by deleting obsolete chart objects before anything new is created, minimizing resource usage. Input parameters allow customization in text position,... 👉 Read | CodeBase | @mql5dev #MQL5 #MT5 #Indicator

The indicator is compatible with all symbols, functioning effectively across multiple time frames. It utilizes color-coded signals to clearly represent the prevailing market trend, distinguishing upward from downward movements. Users can customize several settings including time-frame, moving average (MA) period, shift, method, and price type for tailored analysis. An example demonstrates the application of three MA lines over 5, 10, and 15-minute intervals displayed on a 5-minute chart. It's important to note that while the indicator plots the MA line, it does not display Heiken-Ashi candles. However, it computes Heiken-Ashi candle data, and the CalculateHeikenAshi function can be modified for new OHLC calculations. Heiken-Ashi smoothed calculations deliver a robust trend-following tool, advantageous for swing trading and entry filtering. Alternativ... 👉 Read | Signals | @mql5dev #MQL5 #MT5 #Indicator

Vector Autoregression (VAR) models are crucial for analyzing time series data involving multiple variables. Unlike ARIMA, which focuses on univariate series, VAR models capture the relationships among several time series by considering their interdependencies. These models were introduced by Clive Granger in the 1960s and have since become significant in econometrics. The key feature of VAR is its ability to model each variable as a function of its lagged values and those of other variables. This multivariate approach is beneficial in systems where variables influence each other. Implementation in Python involves ensuring data meets assumptions like linearity, stationarity, and no multicollinearity. When applying VAR to financial data, particularly OHLC values, ensuring data stationarity is paramount. This typically requires differencing to stabilize me... 👉 Read | AlgoBook | @mql5dev #MQL5 #MT5 #VAR
