This code example shows how to retrieve the highest high and lowest low across a specified time interval for the current symbol and chart timeframe. It maps the start and end times to bar indexes, then uses the platform's highest- and lowest-value functions…

This brief note describes a chart indicator that displays the length of drawn trend lines in points. It adds a point count to existing trend lines and to lines drawn later, allowing users to compare or measure trend distances by moving a line on the chart.…

The Glitch Index is a technical indicator designed to express how far an applied price deviates from a moving average adjusted by the moving average’s rate of change. Its inputs are the moving average period and method, the ROC lookback period, and the price…

The indicator tracks one active support level and one active resistance level near the current price. It identifies swing highs and lows using configurable bars on both sides for confirmation, then projects the selected levels forward. A level counts as…

The indicator uses a five-period simple moving average to classify the current trend as upward, downward, or weak. It compares the current average with its previous value: a ratio above one signals an uptrend, while a ratio below one signals a downtrend. The…

This note describes an Ultra Trend indicator that estimates trend direction from the slopes of moving averages across different periods. It says the indicator commonly uses JMA averages, while this version substitutes a Zero-Lag Double Exponential Moving…

The document explains a basic price-channel indicator calculated over a selected number of bars. Its default channel uses the minimum Low and maximum High across the lookback, marking the observed price range. It also describes an alternative construction in…

The document outlines a set-and-forget trading approach implemented as an MT4 expert advisor. The user supplies the number of pending stop-limit orders, an initial entry price, a stop loss, a take profit, and a position size. The stated idea is to place…

The document describes an indicator that averages several moving-average values calculated from one applied price and moving-average method. Users set a base period, the number of averages, and a period increment scheme. Under additive increments, each…

This brief describes an UltraWPR indicator that lets the user choose the chart period from its input settings. The example setting uses a four-hour timeframe, allowing the indicator to display Williams %R calculations based on a period different from the…

This document presents a library of trading functions for opening and closing positions and calculating trade size. Its sizing routine estimates the loss budget from account equity or balance and a user-specified risk percentage, then divides that budget by…

This document describes a standalone implementation of the Quantitative Qualitative Estimator (QQE) indicator for MetaTrader 5. It supports the platform’s available chart timeframes and adds automatic second- and third-higher-timeframe options, which adjust…

The document describes ColorBulls, a chart indicator based on the Bulls Power measure. It presents the result as a colored histogram and allows the user to choose which price series—open, close, high, or low—feeds the calculation. The resulting indicator is…

The document introduces a version of the Blau Stochastic indicator that lets the user select the timeframe used for its calculation through an input parameter. This allows the indicator to draw information from a chosen chart period, such as a higher…

The document describes a position-size calculator that uses a trader’s chosen percentage risk and stop-loss distance to determine lot size. The stop can be specified as a fixed number of points or as a multiple of Average True Range, linking the size of a…

The Weighted CCI is described as a two-line oscillator with fast and slow Commodity Channel Index components. Its calculations incorporate the relationship between fast and slow Average True Range values, with a weighting input intended to control ATR…

This note explains how to use an indicator to display labeled trade levels on MetaTrader 5 charts. It can replace the platform’s native trade-level display on a standard chart, or add levels to custom charts where native levels are unavailable. The note says…

This document describes a MetaTrader indicator that detects bullish and bearish pinbar candlesticks from price action and marks them on the chart. It can issue platform, email, and push notifications, and is offered for both MT4 and MT5. The indicator does…

Delta WPR compares fast and slow Williams %R (WPR) oscillators to classify market conditions. Its histogram uses the slow oscillator’s position relative to a configurable level and the fast oscillator’s position relative to the slow one. When the slow…

This document describes an Expert Advisor that trades from signals produced by the iWPRSign indicator. A signal is acted on when a colored indicator icon appears at the close of a bar. The system depends on a separately compiled indicator file, so it cannot…

The document introduces an implementation of the simple moving average intended to address shortcomings the author sees in existing versions. It argues that some implementations become slower as the lookback period grows because they repeatedly loop over…
