This document describes an RSI candle-volume indicator that smooths both its calculated candle values and its changing overbought and oversold levels. It lists configurable inputs for the RSI period, volume type, threshold levels, gap, smoothing method,…

This indicator estimates how a symbol’s intraday range varies by hour and displays the results beside price with shaded Asian, London, and New York session windows. It groups historical bar ranges by the hour each bar closes, averages them across the…

The article describes a framework for identifying crowded trading and distinguishing a bubble’s buildup from its unwinding. It estimates asset clustering from covariance and principal components, using the concentration of sector returns in important…

The document describes a trading-platform button that closes all open positions across instruments in one action. It focuses on the control logic used when an order cannot be closed: the revised approach checks the platform’s last error and stops processing…

This note describes a variation on the Keltner channel that replaces the conventional average true range input with an adaptive ATR. It retains the classic channel’s simple moving average as its middle line, so the adaptation affects the channel width rather…

ColorRSI_X20 is an RSI indicator presentation feature that colors its lines according to their position relative to overbought and oversold areas. The description says users can adjust the style and color of the first indicator line when starting the…

The document describes a modified exponential moving average intended to change how quickly the average responds while adding implicit smoothing. EMA is presented as a first-order filter whose weights decline exponentially with age, and whose recursive…

This document describes a multiple-timeframe moving average indicator that reads values from the H4 and H1 timeframes, allowing a trader to view those readings while using a different chart timeframe. Its stated purpose is to retrieve an indicator value from…

This brief indicator description presents Kalman-filter velocity as a smoothed measure of price momentum. Its multi-timeframe version adds three higher-timeframe views beyond the standard chart intervals available in MetaTrader 5: the first, second, and…

This indicator uses Slow Stochastic values calculated on a selected symbol and timeframe to display a colored direction signal on a chart. It can also produce alerts, audio notifications, and mobile push messages. Users can configure the stochastic periods,…

This document describes an MT4 indicator intended to help traders think about positions and risk in percentage terms instead of monetary amounts. Its rationale is behavioral: traders with the same plan and market information may act differently because…

The document introduces the Laguerre Filter as a smoothing indicator based on Laguerre polynomials. It says the indicator is intended to show both short-term and long-term trend direction, and gives a simple signal rule: consider buying when the line is…

This document describes an MQL4 Expert Advisor structure for running multiple trading strategies independently or together. Each strategy is treated as a separate instance of a shared EA class and can have its own identifier, trading schedule, risk controls,…

This brief description introduces a higher-timeframe variant of a MaxminChannelWithSlope indicator. It says the chart period can be selected through an input parameter, with a four-hour period shown as the default, so the indicator can use data from a…

The document describes a script for placing a pending sell stop order at a trigger level below the current price. It sets stop-loss and take-profit distances in points from the trigger and allows the trader to set order volume through a money-management…

The document explains a MetaTrader trade function that sizes positions from a risk budget and sets stop distance using the asset’s average true range. It calculates the allowed risk as a percentage of free margin, converts an ATR multiple into stop-loss…

The MultiRVITrend_x10 indicator displays the Relative Vigor Index (RVI) state across ten timeframes. Each line represents one timeframe, with pink indicating an oscillator reading below its oversold threshold, blue indicating a reading above its overbought…

This document explains a notification utility for trading software. It describes four message controls: showing an alert in a separate window, sending a push message to configured mobile terminals, writing a message to the log, and providing the message…

This brief programming note addresses a common Expert Advisor problem: identifying whether the system itself has open orders when the platform’s total-order count also includes orders placed manually. It introduces a boolean function called Check_Open_Orders…

This indicator example smooths the OsMA time series by filtering higher-order harmonics in its spectrum. The description presents the approach as a way to smooth indicator values while introducing very little delay, and says that the same method can be…

This Expert Advisor trades breaks of the upper or lower boundary of the MA_Rounding_Channel indicator. A signal is evaluated when a bar closes, so the described trigger is a confirmed close beyond a channel edge rather than an intrabar touch. The text…

This indicator pairs the Commodity Channel Index with a moving average calculated from the CCI values. The CCI uses a configurable lookback period and applied price; its resulting series is then smoothed using a separately configurable moving-average period…

This document describes a version of the EMAPredictive3 indicator that lets a user select the chart timeframe through an input parameter. It identifies H4 as the default timeframe and notes that the indicator depends on the separate EMAPredictive3 file being…

This document explains a linear regression line fitted to closing prices over a sequence of time periods. The line has an intercept and a slope: the intercept represents the fitted starting level, while the slope describes how the fitted value changes as the…
