What is MT4 error 4051?

The MT4 error 4051 is a MetaTrader OrderSend error suggesting the trading platform is denying an order due to an invalid trading lot amount.

Whenever an MT4 receives a trade request, it thoroughly examines the parameters of the order. When an EA sends an order request, the system automatically verifies the maximum and minimum limit of trading volumes allowed for the particular entry. At any point, the platform detects an order with a trading lot that you are not permitted to execute; it denies the order request showing ERR_INVALID_FUNCTION_PARAMETER_VALUE.

An OrderSend error 4051 doesn’t necessarily mean the system rejects all the trade requests or disables your trading bot permanently. The MT4 executes an order immediately when it comes with an appropriate amount of trading lot. On the other hand, the restriction over the trading volume prevents your account from suffering unexpected losses due to the wrong parameters of an EA.

Why does MT4 error 4051 happen?

You are exceeding your trading limit

The minimum order limit in MT4 is 0.01 lots, and the maximum limit is 200 lots. If your bot determines a trading lot less than 0.01 or greater than 200, the system will reject the order and show the OrderSend error 4051.

In some cases, your broker server might fail to read the lot amount correctly. For instance, you are trying to execute an order with 0.01 volume, but the minimum order limit of the broker is 0.1. So the server will define the volume as invalid since it turns lesser than the minimum order limit.

Conversely, if you ever try to place an order with more than 200 lots at a time, the MT4 will still refuse to activate the order because it exceeds the maximum trade volume limit.

Your EA is generating inappropriate order parameters

Such problems mainly occur due to an error in EA coding. A malfunction in the programming code may tempt your bot to produce unrealistic trading lot figures which are not recognized as valid parameters by MetaTrader or the broker server.

Apart from an invalid trading lot, your trade can be disallowed for the malfunction of other parameters. For instance, you cannot place a buy order with a stop-loss limit greater than your trade entry or take profit level. These types of problems may happen for two reasons:

An error in the EA coding
The EA is not compatible with the trading system

How to fix MT4 error 4051?

How to fix OrderSend error for invalid lot amount

Use NormalizeDouble in your code

When the system confirms an invalid function parameters value, you may consider using the NormalizeDouble function:

Parameters:
value – determines a value with a floating point.
digits – determines the accuracy formate such as the number of digits after the decimal point.
Please note that you must normalize all the values calculated for stop-loss, take-profit, and pending order prices.
Adjust the value of NormalizeDouble
Sometimes a normalized number may become greater than the DoubleToString value like the following example:
Make sure normalized figures are rounded
Here is an example showing how to keep the normalized values round figured:
Broker trading limitations for lot size
f your system still shows the OrderSend error 4051, it might be an issue with your broker trading limitations. In that case, contact the broker and try to be more specific about their maximum and minimum limit of trading lots.

Я забил код в скрипт, и нормально открывает по рынку, без ошибок…

Кстати, это условие:

if (SellTicket==0)

{

}

Если это скрипт, то условие совершенно бесполезное, так как ограничивать количество ордеров в скрипте не имеющем циклов, без смысленно.

Но если этот код из експерта, то так вы тоже не ограничите количество ордеров, так как переменная int SellTicket; инициализируется(обнуляется) в функции int start(){} на каждом тике.

Нужно вынести int SellTicket; за пределы Старта, то- есть вверх!

И тогда это условие будет физически ограничивать количество устанавливаемых ордеров, так как при установке ордера переменная получит не нулевое значение.

Мэкс, спасибо за комментарии. Я внёс некоторые изменения. Сразу уточню — это часть советника. Но, ошибка 130 может возникать только в строке где OrderSend.

Почему-то в 4-хзнаке всё работает, а в пятизнаке — выдаёт по-прежнему ошибку 130.

Возможно, как опытный программист вы сможете найти неточность или роковую ошибку пятизнака.

Заранее благодарен, если подскажите.

MT4 Error 4051: How to Fix Invalid Trading Lot Amount

What is MT4 error 4051?

The MT4 error 4051 is a MetaTrader OrderSend error suggesting the trading platform is denying an order due to an invalid trading lot amount.

Why does MT4 error 4051 happen?

You are exceeding your trading limit

Conversely, if you ever try to place an order with more than 200 lots at a time, the MT4 will still refuse to activate the order because it exceeds the maximum trade volume limit.

Your EA is generating inappropriate order parameters

An error in the EA coding
The EA is not compatible with the trading system

How to fix MT4 error 4051?

How to fix OrderSend error for invalid lot amount

Use NormalizeDouble in your code

When the system confirms an invalid function parameters value, you may consider using the NormalizeDouble function:

Parameters:
value – determines a value with a floating point.
digits – determines the accuracy formate such as the number of digits after the decimal point.
Please note that you must normalize all the values calculated for stop-loss, take-profit, and pending order prices.
Adjust the value of NormalizeDouble

Sometimes a normalized number may become greater than the DoubleToString value like the following example:

Make sure normalized figures are rounded

Here is an example showing how to keep the normalized values round figured:

f your system still shows the OrderSend error 4051, it might be an issue with your broker trading limitations. In that case, contact the broker and try to be more specific about their maximum and minimum limit of trading lots.

В истории есть закрытые ордера.

Выбирать ордер нужно в цикле (в общем случае)
Например так (МТ4) —

Дело не в том, какой цикл использовать (можно хоть for, хоть while), а в том, как он построен. В коде, который Вы привели, цикла нет вообще, выбирается ордер, которого заведомо нет в списке. Проверки успешности выбора ордера тоже нет.

Параметры в функции OrderSend вообще очень странные.

Не нужно рассчитывать на историю счета. В МТ4 пользователь может изменить глубину отображения истории, чем собьет с толку любой алгоритм, ориентирующийся на нее. Лучше отслеживать наличие ордеров, открытых советником, в списке рабочих ордеров. И только тогда, когда ордер исчез из этого списка (был закрыт), открывать следующий ордер.

Эксперт работает не с одним ордером? Тогда все усложняется. При открытии каждого ордера нужно запомнить его тикет в собственном массиве. А потом на каждом тике проверять, существует ли этот ордер.

Функция OrderClose — Error 4051

Решил начать программировать на mql. Написал советник , проверяя как открываются и закрываются ордера. Открывается ордер при соответствующих условиях нормально, а при закррытии появляется Error 4051 — Invalid ticket to OrderClose Function. Помогите пожалуйста разобраться, что я делаю не так. Код советника ниже.

double MA;
MA=iMA(NULL,0,MA_Period,0,MODE_SMA,0,0);
int T;
T=OrdersTotal();
int ticket;
bool a;

После открытия позиции тикет у Вас не сохраняется. И при следующем запуске start переменная ticket инициализируется нулём. Нужно объявить ею как статическую или глобальную чтобы её значение сохранялось. Также полезно контролировать выполнение функции OrderSelect , например:

Что я не так зделал, подскажите плиз

выбираю ордер, узнаю тип, узнаю тиккет, пытаюсь удалить отложенный ордер — выдаёт ошибка 4051

Недопустимое значение параметра функции

if (a2>1)
OrderDelete(ticket2);
Alert (GetLastError()); // Сообщение об ошибке 4051

Error 4051 occurred deleting an object

I use a routine to create an entire table as a summary of all my active trades and each object has a name created by using its x and y positions.

The table maybe 10 columns by 10 lines — i.e. 100 objects created in the same routine — but all very similar

I noticed the following error 4051 and created some additional ‘FileWrite’ statements to try and track the error.

It is only COD330_130 that appears to generate this problem.

The next line would be — say — COD345_130 and no problem

There don’t appear to be any other problems and the EA continues to work

The ‘FileWrite’ generated the following

1 ObjName = COD330_130, Object_label = EURCHF colour = clrMidnightBlue xd = 330 yd = 130, 4051 invalid function parameter value

Any ideas appreciated.

[. ] Any ideas appreciated.

Are you sure that the error 4051 is generated during the code which you have posted, rather than before it?

It seems far more likely that the sequence of events, and the issue, is as follows:

Block of code earlier to that which you have posted, which does something leading to error 4051
Then the code which you have posted, which doesn’t generate an error
Checking GetLastError() then gives you the earlier error, which happened before the block of code which you are querying here.

Error Code 4051 Incorrect Params only on Sell Orders

This is my first posting on this forum, so please excuse any formatting/procedural errors. I am having difficulty with the Order Modify function. I use an ECN, so I must send the order with 0’s in the SL and TP fields and then use the Order Modify function.

The stop loss and take profit values are inserted perfectly with the buy order code, but fail when a sell order is input, resulting in the 4051 error code. This refers to invalid parameters on the take profit field, but I am using the same approach (not the calcs) on my buy order.

There is obviously something pretty basic that I am missing. I would really appreciate some help/insight on the extent of my error.

Thanks very much

Always check your return codes. What are Function return values ? How do I use them ? — MQL4 forum
What is the value of OpenPrice ?

RaptorUK :
Open price for a Buy is Ask, for a Sell it is Bid, how far has price moved between placing your Buy and your Sell ? Don’t use OpenPrice use Ask if you must or use OrderOpenPrice(). Why don’t you print OpenPrice when your OrdrModify() fails ? why don’t you Print Ask, Bid, etc ? don’t you think they are relevant to finding thee cause of your issue ?

I always print values to my journal, but the answer was not obvious until I read the thread on function return values and trapped them. Result was a mod to my code that corrected the problem.

Not sure about your reference to using Ask and Bid. My Order Send uses Ask and Bid as you suggest, and OrderOpenPrice() was used to set the TP and SL. Anyway, the mod to my code was successful.

Thank you both for your time.

For anyone reading this thread, here is the change I made to make the Stop Loss and Take Profit modification. My problem was based on the value of 0 being returned as the Ticket No. Code replaced in pink and code deleted in yellow .

What is MT4 error 4051?

The MT4 error 4051 is a MetaTrader OrderSend error suggesting the trading platform is denying an order due to an invalid trading lot amount.

Why does MT4 error 4051 happen?

You are exceeding your trading limit

Conversely, if you ever try to place an order with more than 200 lots at a time, the MT4 will still refuse to activate the order because it exceeds the maximum trade volume limit.

Your EA is generating inappropriate order parameters

An error in the EA coding
The EA is not compatible with the trading system

How to fix MT4 error 4051?

How to fix OrderSend error for invalid lot amount

Use NormalizeDouble in your code

When the system confirms an invalid function parameters value, you may consider using the NormalizeDouble function:

Parameters:
value – determines a value with a floating point.
digits – determines the accuracy formate such as the number of digits after the decimal point.
Please note that you must normalize all the values calculated for stop-loss, take-profit, and pending order prices.
Adjust the value of NormalizeDouble
Sometimes a normalized number may become greater than the DoubleToString value like the following example:
Make sure normalized figures are rounded
Here is an example showing how to keep the normalized values round figured:
Broker trading limitations for lot size
f your system still shows the OrderSend error 4051, it might be an issue with your broker trading limitations. In that case, contact the broker and try to be more specific about their maximum and minimum limit of trading lots.
