Metatrader Error Codes – MQL error codes received by the trading expert in the terminal. Solutions.

Description

Error codes

GetLastError() is a function that returns error codes. Error code constants are defined in the “stderror.mqh” file. To display text messages, use the ErrorDescription() function defined in the “stdlib. mqh” file.

Error codes returned by the trade server or client terminal:

In view of the frequent requests to me, as a specialist in the field of programming advisers on MT4, with questions about errors, I will try to tell you the most common mistakes of a trader and errors of advisers, how to eliminate them, and the reasons for their occurrence.

Each Expert Advisor has its functional mode, but we will proceed from a standard set of problems and common errors of Expert Advisors.

So, let’s begin. 

A brief reference on errors is given in  Error Codes, as well as in the MetaTrader4 terminal itself.
Based on them, we will try to describe the problem and how to solve it in the style of “Guidelines for Electronic Engineering Errors”.

If your error is not in this table, or the solutions did not help, contact the author of your adviser, but before that, use the article 

Log files for detailed consideration of the problem with robots

Common errors and how to solve them

Error number	Brief  description	Possible causes	Solution method
Graph Mismatch Errors	Errors on the DC server: incoming ticks are not processed very accurately on all timeframes.	Errors on the DC server: incoming ticks are not processed very accurately on all timeframes.	Testing immediately after loading from the archive does not reveal errors because only minutes are loaded, which are converted into other TFs according to the correct algorithm. At this point, there are no mismatch errors. And then, when real quotes begin to arrive, mismatches accumulate again.
TestGenerator: unmatched data error	Error in quotes archive data	1. Incomplete quote data from your broker 2. Damaged quote base 3. You are trying to test the EA before today’s date. 4. asynchronous data of older TFs in the archive	An error occurs either when an error is not defined or when there is none.
Error 0 or 1	No error, error not known	1. Previous reasons for the error in a persistent request.	Exclude handling of errors 0 and 1 in the Expert Advisor
error 4, 146	The broker prohibits the use of the order expiration date	The trade server is busy	1. Restarting the terminal 2. Optimizing the EA code using error handling functions.

1.

The maximum lot can be 5 lots or 999 lots, and others. 4. Specify the number of bits on your Server.  If, for example, the lot size = 1, then you can open a lot 0.1, 0.5, or 1.2, and so on, with 1 decimal place. If the lot have 2 digits, then based on the minimum lot, the lot can be 0.01, 0.06, 0.17, or 1.48.  Also, in some DCs, there is an order of the degree of lots. For example, you can open 0.5 and 1 But 0.6 cannot be opened. Check wServerur broker about how to place lots.	Wrong price	1.
