This indicator description explains an option to calculate Trend Envelopes from smoothed or filtered prices rather than raw prices. The selected filter is a parabolic weighted moving average, presented as a fast method for filtering price data. The stated…

This expert advisor uses the magnitude and direction of price-time correlation to generate trading signals. It offers trend-following and reversal modes, and four ways to calculate correlation: Pearson, Spearman, Kendall, and Fechner. ADX, Bollinger Bands,…

This indicator plots four horizontal price levels based on a user-selected bar. The two basic levels sit above that bar’s high and below its low by a configurable shift. Two additional guide levels are placed farther outward: the upper guide adds the…

The i-ParamonWorkTime indicator marks two user-configurable intraday intervals associated with high market volatility. Inputs include the number of historical days considered, start and end times for each interval, display colors, and a range option. The…

The Volume Flow Oscillator (VFO) is presented as an indicator derived from On Balance Volume and described in a 2004 issue of Technical Analysis of Stocks & Commodities. It uses volume-related calculations to produce a reading around a zero line. Positive…

The document describes an Expert Advisor that trades from the ColorBullsGap indicator. It waits for a bar to close and generates a signal when the indicator’s histogram changes color, then uses that signal to open trades. This is a simple indicator-driven…

This indicator combines three stochastic oscillators, with configurable periods and smoothing choices for their %K and %D lines. The first oscillator uses the chart timeframe, while the second and third can use selected higher timeframes. Higher-timeframe…

Exp_Fast2 describes a MetaTrader Expert Advisor that trades signals from the Fast2 indicator. A signal is generated when the indicator’s main and signal lines cross as a bar closes. Running the advisor requires the compiled Fast2 indicator file in the…

This brief indicator description presents a way to visualize price series processed by a Kalman filter as a sequence of candlesticks. The filtered series is rendered in candle form, which the source suggests may make the resulting analysis more informative…

This document describes a version of the Slow Stochastic indicator that lets the user select the timeframe used for its data through an input parameter. The example default is a four-hour period, allowing the indicator to display a stochastic calculated on a…

The document presents DT-Pirson as a volatility indicator intended to distinguish stronger trends from flat market conditions. It says readings above 0.5 indicate an approximately strong trend, while values approaching zero correspond to a flat market. This…

This document describes an indicator built from Wilder’s double-smoothed exponential moving average, adjusted using a method attributed to Alexander Uhl. It adds floating levels around the indicator and offers several ways to display color changes: crossings…

This document explains how to build fuzzy inference systems in MQL4 with the FuzzyNet library. It covers Mamdani and Sugeno model types, fuzzy input and output variables, membership functions, terms, and rule sets. Mamdani rules map fuzzy conditions to fuzzy…

Hans_Indicator_x4 is described as an indicator that builds expanding corridors across time zones. The initial formed corridor spans four hours, and the expansion period spans sixteen hours. Its inputs let the user set the local start hour and a destination…

The range-weighted exponential moving average is defined as the exponential moving average of price multiplied by a range-based weight, divided by the exponential moving average of that weight. This construction differs from a regular range-weighted average…

This indicator is designed to help assess how spread affects the potential profitability of strategies that forecast the market one bar ahead. Its output can be treated as a unit-volume position in a custom tester, allowing a researcher to consider accuracy…
