MyRsi - indicator for MetaTrader 5

John Ehlers introduced a variation of rsi calculation (as a part of another indicator) that he decided to call MyRSi. Since it produces results different then the built in rsi, it seemed as logical step that we should have that indicator too. Kept the name, but again : that name is used by John Ehlers (not me)

MyRsi with NET - indicator for MetaTrader 5

In December 2020 issue of TASC, John Ehlers published an indicator called MyRsi with NET (MyRsi with Noise Elimination Technology) in which he uses a sort of Kendall (auto)correlation to filter out signals

DMH - indicator for MetaTrader 5

In the December 2021 issue of TASC article “The DMH: An Improved Directional Movement Indicator”, John Ehlers explores a method of modernizing directional movement with Hann windowing. Directional movement has been a mainstay in technical analysis and has been an examined concept by traders for decades. When the original directional movement indicator was created by J. Welles Wilder, technology did not easily allow for complex calculations. Ehlers proposes it is time for an upgrade. While the DMH indicator defaults to using Wilder’s 14 bars, Ehlers suggests the length should be at the discretion of the trader or can be determined by optimization if the DMH is used in a strategy.

The Hurst Coefficient Indicator - indicator for MetaTrader 5

The "The Hurst Coefficient" indicator was published by John Ehlers in Cycle Analytics For Traders, pp. 67-68.

It is an indicator that shows whether a stock is in an uptrend or a downtrend. Buy when the indicator line is green and sell when it is red.

Rsi with Hann windowing - indicator for MetaTrader 5

In his article in January 2022 issue of TASC, “(Yet Another) Improved RSI,” John Ehlers explains how he enhances the RSI by taking advantage of Hann windowing. The RSIH indicator provides a smoother calculation than the classic RSI and has a zero mean. The inherent smoothing in the computation removes the need for supplemental filtering.

Elegant oscillator - indicator for MetaTrader 5

In his article in February 2022 issue of TASC, “An Elegant Oscillator: Inverse Fisher Transform Redux,” author John Ehlers explains how he uses the inverse Fisher transform to create an indicator he calls the elegant oscillator.

In this article, we will share one of the most important topics in programming which lead to coding smoothly and easily, and help us to apply the concept of (DRY) which is the shortcut of (Do Not Repeat Yourself) as developers or programmers. In addition to raising the security of any created software, and other of features. We will talk about Object-Oriented Programming (OOP) and how we can use this concept and code it in MQL5 (MetaQuotes Language) by understanding the basics of OOP first, then understanding how to use it in MQL5 by seeing some applications.
