In МТ3, management of open positions was rather time-taking. Traders had at their disposal a rather limited tool set to work with the list of open and closed positions. The problem of distinguishing between "own" and "someone else's" positions was solved in rather complicated ways. In МТ4, the situation has cardinally changed.
Now, trader can use a great variety of mql4 magic number and fully manage all open positions and placed orders and get access to information about any closed positions. A special parameter mql4 magic number MagicNumber was added to identify orders. This is the parameter our article will deal with. May be used as user defined identifier.
This number will consequently be used to distinguish the above order from others, mql4 magic number. There is no use or even possibility applying this feature when trading manually, but it is really unexpendable when trading using an expert automated trading.
Example 1: A human trader and an expert are trading in the client terminal at the same time. Task: The expert must trade according to its algorithm and may not do anything with positions opened manually. Solution: The mql4 magic number must assign a unique, non-zero MagicNumber to the position being opened.
In future, it must manage only positions, the MagicNumber of which is equal to the preset one. Example 2: Two experts with different algorithms are trading in the client terminal at the same time.
Task: The expert must manage only "their" orders. Solution: Each expert must use its unique non-zero MagicNumber when opening positions. In future, they must manage only positions, the MagicNumber of which is equal to the preset one. Example 3: Several experts, a human trader and an assisting expert realizing a non-standard Trailing Stop are operating mql4 magic number the client terminal simultaneously.
Task: Trading experts must work according to their algorithms and may not do anything with positions opened mql4 magic number. The assisting expert that realizes Trailing Stop may modify only positions opened manually, but not those opened by other experts. Solution: The trading experts must use unique MagicNumbers and manage only "their" positions. The assisting expert must modify only those positions having MagicNumber equal to 0. All three examples are quite realistic, and the users could probably have set such problems for themselves.
In all three cases, the MagicNumber is used to solve it, mql4 magic number. This way is not the unique one, mql4 magic number, but mql4 magic number easiest. Now let us solve the specific task: create an expert that could work only with its "own" positions without paying attention to positions opened manually or by other experts.
Let us first write a simple expert, for which the signal to open a position will be when the MACD indicator meets zero line.
The expert mql4 magic number look like this:. Everything is ok, but there is one problem here, mql4 magic number. If we mql4 magic number a position during the expert's operation, it will consider this position as its "own" and act accordingly. This is not what we want. Now, when the expert is working, the user can open positions manually. The expert will not touch them. There are cases where the same EA must trade on the charts of the same symbol, but with different timeframes, for instance.
If mql4 magic number try to attach our expert to the chart EURUSD, H1, and mql4 magic number the EURUSD, M30, simultaneously, they will interfere each other: each will "consider" the open position to be "its" position and modify it at its discretion.
But this is not very convenient. If there are many experts used, one can just get entangled among their IDs. We can meet this problem using the chart period as MagicNumber. How shall we do it? Similarly, using the above code, the user can improve his or her EAs and "teach" them to distinguish "their" positions from the "foreign" ones. Translated from Russian by MetaQuotes Software Corp. Andrey have you considered having the EA generate its own ID at start up and have the ability to not only see its own orders but to be able to track each of its orders even if it has orders open.
It would have to have the ability to recover its ID or restates as well. With that you can create a function to be called in the int function at start up. Example: there are two open orders with magic numbers "1" and "3", mql4 magic number, so the minimal available is "2", mql4 magic number. You agree to website policy and terms of use.
