MQL5: Create Your Own Indicator
MQL5: Create Your Own Indicator
What is an indicator? It is a set of calculated values that we want to be displayed on the screen in a convenient way. Sets of values are represented in programs as arrays. Thus, creation of an indicator means writing an algorithm that handles some arrays (price arrays) and records results of handling to other arrays (indicator values). By describing creation of True Strength Index, the author shows how to write indicators in MQL5.
Drawing Channels - Inside and Outside View
Drawing Channels - Inside and Outside View
I guess it won't be an exaggeration, if I say the channels are the most popular tool for the analysis of market and making trade decisions after the moving averages. Without diving deeply into the mass of trade strategies that use channels and their components, we are going to discuss the mathematical basis and the practical implementation of an indicator, which draws a channel determined by three extremums on the screen of the client terminal.
Testing Performance of Moving Averages Calculation in MQL5
Testing Performance of Moving Averages Calculation in MQL5
A number of indicators have appeared since the time of first Moving Average indicator creation. Many of them use the similar smoothing methods, but the performances of different moving averages algorithms have not been studied. In this article, we will consider possible ways of use the Moving Averages in MQL5 and compare their performance.
The ZigZag Indicator: Fresh Approach and New Solutions
The ZigZag Indicator: Fresh Approach and New Solutions
The article examines the possibility of creating an advanced ZigZag indicator. The idea of identifying nodes is based on the use of the Envelopes indicator. We assume that we can find a certain combination of input parameters for a series of Envelopes, whereby all ZigZag nodes lie within the confines of the Envelopes bands. Consequently, we can try to predict the coordinates of the new node.

The opportunity to implement a full fledged multi-currency regime became possible only with the public release of MetaTrader 5 and the MQL5 programming language. In this article we propose a way to analyze and process all incoming ticks for several symbols. As an illustration, let's consider a multi-currency RSI indicator of the USDx dollar index.
Event handling in MQL5: Changing MA period on-the-fly
Event handling in MQL5: Changing MA period on-the-fly
Suppose that simple MA (Moving Average) indicator with period 13 is applied to a chart. And we want to change the period to 20, but we do not want to go to indicator properties dialog box and edit the number 13 to 20: simply tired of these tedious actions with mouse and keyboard. And especially we don't want to open indicator code and modify it. We want to do all this with a single press of a button - "up arrows" next to the numeric keypad. In this article I'll describe how to do it.

Auto detection of extreme points based on a specified price variation
Auto detection of extreme points based on a specified price variation
Automation of trading strategies involving graphical patterns requires the ability to search for extreme points on the charts for further processing and interpretation. Existing tools do not always provide such an ability. The algorithms described in the article allow finding all extreme points on charts. The tools discussed here are equally efficient both during trends and flat movements. The obtained results are not strongly affected by a selected timeframe and are only defined by a specified scale.
