File separator - special symbol; the entry that is written to a file to separate the information lines. We have put a lot of effort into development and would like to move on with traders and abandon the older builds.

I was wondering if anybody knows how to change the labeling on the y-axis of an indicator? In order to allow the program to differentiate one file from another the file descriptor is set in accordance to every opened file. It is the first step to program my own divergence-indicator. The IndicatorCounted function returns the number of bars unchanged since the last indicator call.

The descriptors of the files that are opened in the module cannot be passed to other modules libraries. This mode is used, if you need to add some information to the file that already contains some other information.

File Operations

Errors "unknown symbol" and "semicolon expected" To fix this error, you need to use correct function or variable names. The easiest way is to check the divisor before the division operation and report an incorrect parameter value: So, values of timeseries elements with indexes from 0 to 29, i.

The line 1 and column 1 as shown on other attached pict. The second entry is the text description of the event. Compiler Warnings Compiler Warnings are informative and are not error messages, but they indicate possible error sources.

Therefore, you should assign the file extension considering the program if necessary that will usually be used to view the file. This article is intended for developers who would be interested in using SQL in their projects.

File Names and Directories The name of a working file must be composed according to the requirements of the operating system. Names of global and local variables coincide If variables on the global and local levels have similar names: There is a simple and reliable way to do this - analyzing the opening time of a zero bar.

Data Structure in MetaTrader 4 Build and Higher MetaTarder 4 build features the new structure and location of the client terminal files.


Each line contains two entries. Conclusions The article describes common problems that may occur during compilation of old programs that contain errors. A try to open a file in this mode results in opening a file of a zero length.

Indicator values on previously calculated bars do not need recalculation, so for faster calculations you only need to process the last few bars.

Even if there was some information in the file before opening, it will be erased.FileWriteArray. The function writes arrays of any type except for string to a BIN file (can be an array of structures not containing strings or dynamic arrays). The function requires obligatory combination of FILE_READ, FILE_WRITE or FILE_READ|FILE_WRITE modes with the FILE_BIN or FILE_CSV mode.

For example: it is necessary to use the combination of FILE_CSV|FILE_READ to read the information from a text file, and it is necessary to use the FILE_BIN|FILE_READ|FILE_WRITE. File sharing. In the new MQL4, FILE_SHARE_WRITE and FILE_SHARE_READ flags should explicitly be specified for shared use when opening files.

If the flags are absent, the file is opened in exclusive mode and cannot be opened by anyone else till it is closed by the user who opened it. FileWrite.

The function is intended for writing of data into a CSV file, delimiter being inserted automatically unless it is equal to 0. After writing into the file, the line end character "\r\n" will be added.

Sample double num_array[15]={ int ArrayMinimum(double array[] else { Print("Series array cannot be initialized!"). double value) Sets all elements of numeric array to same value. Print("Max value = ".1 double myarray[10] Arrays.

A large part of information processed by application programs is contained in arrays. Concept of Arrays. Array is an arranged set of values of one-type variables that have a common name.

Arrays can be one-dimensional and multidimensional. The maximum admissible amount of dimensions in an array is four.
