Articles on trading system automation in MQL5

You must admit that it sounds alluringly - you become a fortunate possessor of a program that can develop for you a profitable automated trading system (ATC) within a few minutes. All you need is to enter desirable inputs and press Enter. And - here you are, take your ATC tested and having positive expected payoff. Where thousands of people spend thousands of hours on developing that very unique ATC, which will "wine and dine", these statements soundб to put it mildly, very hollow. On the one hand, this really looks a little larger than life... However, to my mind, this problem can be solved.

A simple concept described in the article allows those developing automated trading systems in MQL4 to simplify existing trading systems, as well as reduce time needed for development of new systems due to shorter codes.

Successful and comfortable trading using MT4 platform without detailed market analysis - is it possible? Can such trading be implemented in practice? I suppose, yes. Especially in terms of the automated trading!

The article deals with the most common errors that occur in developing and using of an Expert Advisor. An exemplary safe automated trading system is described, as well.

Requote is a scourge for many Expert Advisors, especially for those that have rather sensitive conditions of entering/exiting a trade. In the article, a way to check up the EA for the requotes stability is offered.

The article substantiates approach to building a trading system as a sequence of opening and closing the interrelated orders regarding the existing conditions - prices and the current values of each order's profit/loss, not only and not so much the conventional "alerts". We are giving an exemplary realization of such an elementary trading system.

The article compares the time and results of Expert Advisors' optimization using genetic algorithms and those obtained by simple search.

The article describes the use of technical indicators in programming on MQL4.

The article deals with programmed tracking of events in the МetaТrader 4 Client Terminal, such as opening/closing/modifying orders, and is targeted at a user who has basic skills in working with the terminal and in programming in MQL 4.

The article deals with various ways of how to control open positions and pending orders. It is devoted to simplifying of writing Expert Advisors.

All categories classifying trading strategies are fully arbitrary. The classification below is to emphasize the basic differences between possible approaches to trading.

Examined are the most frequent mistakes that lead the first-time programmers to creation of a "super-moneymaking" (when tested) trading systems. Exemplary experts that show fantastic results in tester, but result in losses during real trading are presented.

General principles of considering orders in a large and complex program are discussed.

The article deals with the problem of how to arrange pauses between trade operations when a number of experts work on one МТ 4 Client Terminal. It is intended for users who have basic skills in both working with the terminal and programming in MQL 4.

The article deals with the problem of conflict-free trading of several experts on the same МТ 4 Client Terminal. It "teaches" the expert to manage only "its own" orders without modifying or closing "someone else's" positions (opened manually or by other experts). The article was written for users who have basic skills of working with the terminal and programming in MQL 4.

25 to 30% of all crashlogs received from users appear due to errors occurring when functions imported from custom dlls are executed.

The article deals with the outlook of using MQL4 for more productive work at FOREX markets.

The article deals with realization of charts without skipped bars.

Genetic (evolutionary) algorithms are used for optimization purposes. An example of such purpose can be neuronet learning, i.e., selection of such weight values that allow reaching the minimum error. At this, the genetic algorithm is based on the random search method.

The article gives formulas and the calculation order for data shown in the Tester report.
