The Metatrader 5 Iphone app will feature a uniform design that will seamlessly fit in the Iphone interface. The app is developed from scratch and well be 100% native to the Iphone OS. Also, it will be different from the interface in Metatrader 4 Windows Mobile. The release date is not known yet. If the mobile version of Metatrader 5 is one of the reasons you will buy a smartphone, this information will help you to decide what platform to buy. I personally like the Android OS.

If you want to use Metatrader 4 on your Iphone, you can use tools that create a remote connection to your desktop, where Metatrader 4 is running. For example, you can use the TeamViewer app for Iphone, it connects to any PC around the world and you can remotely control the PC as if you were sitting right in front of it. You can also seamlessly use iPhone to login directly to your PC running MT4 using the PC2ME app. With PC2Me you can remote control of your Windows PC, using your iPhone via the Safari browser. There is also a Iphone app that allows you to monitor your Metatrader 4 accounts using myfxbook.com’s backend:

Actually, the remote connection to the desktop version of the Metatrader terminal is in some cases better than a mobile version of MT for the smartphone. On the smartphone you have always limited computing resources and not all features of the full version of Metatrader. For example, if you are using a expert advisor on your desktop, you can only control it via a remote connection. But if you want to quickly check the market quotes, the mobile version is better.

Introduction

This article is aimed at beginners who wish to learn how to write simple Expert Advisors in the new MQL5 language. We will begin first by defining what we want our EA (Expert advisor) to do, and then move on to how we want the EA to do it.

1. Trading Strategy

What our EA will do:

• It will monitor a particular indicator, and when a certain condition is met (or certain conditions are met), it will place a trade (either a Short/Sell or Long/Buy), depending on the present condition that has been met.

The above is called a trading strategy. Before you can write an EA, you must first develop the strategy that you want to automate into the EA. So in this case, let us modify the above statement so that it reflects the strategy we want to develop into an EA.

• We will use an indicator called Moving Average with a period of 8 ( You can choose any period, but for the purpose of our strategy, we will use 8 )
• We want our EA to place a Long (Buy) trade when the Moving Average-8 (for the sake of our discussion, I will refer to it as MA-8) is increasing upwards and the price is close above it and it will place a Short (Sell) when MA-8 is decreasing downwards and the price is close below it.
• We are also going to use another indicator called Average Directional Movement (ADX) with period 8 also to help us determine whether the market is trending or not. We are doing this because we only want to enter the trade when the market is trending and relax when the market is ranging (that is, not trending). To achieve this, we will only place our trade (Buy or Sell) when above conditions are met and the ADX value is greater that 22. If ADX is greater that 22 but decreasing, or ADX is less than 22, we will not trade, even though the condition B has been met.
• We want to also protect ourselves by setting a Stop loss of 30 pips, and for our Profit target; we will target a profit of 100 pips.
• We also want our EA to look for Buy/Sell opportunities only when a new bar has been formed and we will also make sure we open a Buy position if the Buy conditions are met and we do not already have one opened, and open a Sell position when the Sell conditions are met and we do not already have one opened.

We have now developed our strategy; it is now time to start writing our code.

As little as 5 years ago, the MetaTrader 4 terminal was officially presented to the traders, written completely from scratch and intending to replace the existing, and already popular, third generation terminal of MetaQuotes Software Corp. MetaTrader 4 quickly gained popularity among traders, and as a consequence, in the following years, hundreds of brokers began to provide their services on the MetaTrader 4 platform.

Despite this success, 3 years ago developers decided to create an informatory – trading platform of a new generation, and in November of 2009 the public testing of MetaTrader 5 had begun. We all tend to take a strong liking to the known and the familiar and take a cautious approach to changes. Traders are no exception to this behavior. Therefore we decided to help, all who desired, to understand the differences and advantages of the MetaTrader 5 platform in comparison to the well-known MetaTrader 4.

New markets and instruments

From the beginning, MetaTrader was intended to be a convenient and user friendly platform for trading on the Forex market. Today, it is difficult to even imagine that many years ago, in almost all other terminals, trade was conducted on demand, it was not possible to create your own technical indicators and trading robots, and opportunities for technical analysis were implemented more in words than actual actions. And so, traders who sold through other financial markets began to express a desire to sell through MetaTrader.

With the testing you can assess the qualities of your Expert Advisor on history data before launching it in real trading. Optimization allows choosing the most profitable parameters for your Expert Advisor making it a real efficient one. The Strategy Tester is an indispensable tool for developers of Expert Advisors. It is almost impossible to develop a profitable an error-free Expert Advisor without the tester.

As compared to the tester in MetaTrader 4, the new MetaTrader 5 Strategy Tester is a more powerful and accurate tool. It has obtained the new function of distributed optimization that will be useful in work with compound Expert Advisors. Besides that, the Strategy Tester offers efficient testing of multi-currency Expert Advisors.

“The Strategy Tester is the last component from the set of required tools for efficient development of Expert Advisors. This set also includes the MQL5, MetaEditor, debugger and execution module in the MetaTrader 5 Client Terminal. The absence of a tester was the last obstacle to the wide possibilities provided by the MQL5 environment. We hope that together with the release of MetaTrader 5 Strategy Tester, the number of new MQL5 Expert Advisors will sharply increase”, – Stanislav Starikov, the senior developer of MetaTrader 4/5 terminals and MQL4/5, said.

Introduction

Many developers have accumulated a lot of indicators and trading strategies written in MQL4. To use them in Metatrader 5, they should be converted to MQL5. It’s not so easy to rewrite all programs in MQL5. It would be much easier to convert them, if there were a translation-reference, and better with examples.

In this article I would like to suggest my version of a guide to migrate from MQL4 to MQL5.

Introduction

An Expert Advisor or indicator that doesn’t use standard technical indicators in its code is rare. They are popular both for the beginners and advanced developers of trading strategies. It isn’t difficult to understand the details of indicator creation; the aim of this article is to help with it. We will consider the use of the functions for working with built-in standard technical indicators.

Fundamentals of Using Functions of Standard Technical Indicators

When being called, each function of a technical indicator creates a handle of the object created (indicator’s instance) with specified input parameters. The purpose of the handle is to assign it with this object. It’s quite sufficient to get the data from the indicator buffer and use it in your own calculations.

Creating a source file

To begin with our expert, let’s create it’s source file. We’ll do this pretty much as in the MetaEditor4 by calling the MQL5 Wizard from File -> New menu. On the first step select the Expert Advisor and press Next.

Across this article I’ll use the article ‘error’ as a reference to the conceptual code errors such as wrongly written conditions or wrongly written calculus expressions… Warning: don’t mistake them with the errors signaled by the compiler.

For the ones that don’t know , the purpose of the debugger is to run line by line to code in order to find conceptual programming errors, and to watch the values of the variables realtime.

In MT4, that lacked a debugger, the programmers were using the Print function to find the errors in the code, this being the single method available. This method is difficult to use and the time needed to find the error is way larger compared to using a debugger, because Prin needed a recompilation every time, re-attaching the EA and reading in logs. If we were calling functions giving a wrong result , because they were badly written, we had to go inside that function and attach Print lines to see where were the errors. After repairs, the code had to be cleaned up of redundant Print lines used to find the error.

Right now the debugger works only to test scripts, but we think it will be integrated with the Strategy Tester to work with experts. This is needed also because several buggy EA modules may be run only in rare market conditions, that will not appear while forward testing, but will be revealed while backtesting.

Now the things got simpler, from the same window you can follow the program being run line by line.

In order to use the debugger we have to call the DebugBreak() function where we want the normal execution stopped in order to start execution line by line. If we attach such a script to a chart, this will not stop running, as it will be stopped only if it’s started with the debug mode of the MetaEditor.

To start the script for debugging we have to press Debug->Start or F5 key or it’s dedicated button in the special bar dedicated to the debugger, bar which contains other 3 buttons for passing thru the code.

The group of buttons from the rectangle labeled 1 are the 6 buttons used at debugging. The first 3 buttons are getting in and out from the debug mode, but also to pause. The last 3 buttons are for passing the code in other manners, in the debug mode:

- passing thru the code by Step Into (F11) we go line by line but we enter the functions referred. For instance if we are with the cursor on the line ‘p=prod(a,b)’ and we push Step Into then the cursor will go into the ‘prod’ function and we will be be able to go line by line thru the code of this function;

- passing thru the code by Step Over (F10) we go line by line thru the code but the debugger will jump over called functions (these will be executed, but not line by line in a debug mode).

- Step Out should make the debugger get out of the function where the cursor is, and not close the debug mode, thing which is happening now.

The green arrow labeled with 2 is the current line. If we push F10 (Step Over), the arrow will move to the next line.

Running a code in the Debug mode a new page opens within the Toolbox pageframe, which is divided in two (areas 3 and 4).

In area 3 we see the name of the file that’s being run, the name of the function and the number of the line where we are in the debug mode.

Area 4 is similar to the Watch window from Borland C++ / Borland Pascal or other older IDEs , where can be watched realtime the values and types of variables.

In picture above in area 4 we have 3 variables which we follow : a, s and p. The variable ‘a’ has the value of 5 because we passed the line ‘a=5? where we are initializing it. The variable ‘p’ has the value 0, because this is the default value taken by the integer variables when they are defined, while ’s’ is undefined, because that’s the stop where the execution is stopped, right before it being declared.

These being said I wish you luck writing codes and debugging them.
