Metatrader 4 custom indicator switch
EAs are coded by users. There are no built-in EAs in the client terminal. A script is a program coded in MQL4 and executed by the client terminal only once.
Scripts switcn intended to perform operations that should be executed only once. Swith are coded by users. They are not delivered with the client terminal as built-in programs. A custom indicator is a program coded in MQL4 and called by the client terminal to be executed at every tick. It is basically intended for graphical displaying of preliminarily calculated data, such as lines. Indicators cannot trade. There are two types of indicators: Indicators are considered in detail in Usage of technical indicators and Creation of custom indicators.
You choose the type of the program to write depending on the purpose of the specific program and on the properties and limitations of the different types of programs. Properties of programs Launching a program for execution There is a criterion that distinguishes EAs and custom indicators from scripts. This is their run duration. In Some basic conceptswe mentioned already that programs are launched as often as there is a tick.
How to Toggle Indicators On and Off
This statement is true for EAs and custom indicators, but it indicztor false for scripts. EA and custom indicator. Once you have attached a program EA or Metatrafer indicator to the symbol window, Meatrader program makes some preparations and switches to the tick-waiting mode. As soon as a new tick comes, the program will be launched by the client terminal for execution, then it makes all necessary operations prescribed by its algorithm. Upon completion, the program passes the control to the client terminal, that is it switches to the tick-waiting mode.
This is why not all the ticks result in launching an EA or a custom indicator. Only those ticks that come in when the control is in the client terminal and when the program is in the tick-waiting mode call the EA or custom indicator.
That statement is also for EAs and corporate indicators, but it is left for scripts. the differential makes some preparations and edits to the tick-waiting skip.

The new tick launches the program for execution. Thus, an EA or a custom indicator can operate within a long period of time, being attached to the symbol window and starting to run from time to time as often as a new tick comes in while the program is in tick-waiting mode. Besides, an EA differs from an indicator by the execution order at the first launch of the program. This difference is determined by the specific properties of special functions in the program of a certain type see Special functions. Once attached to the symbol window, an EA makes the necessary preparations contained within init function. Then, it switches to the tick-waiting mode, calling the start function only upon the first incoming tick.
Unlike EAs, a custom indicator both executes init function and calls start function one time to make the first calculation of the indicator value. Later on, at a new tick, the program is launched by calling only start function.
That is, operators are executed according to the algorithm of start function. Unlike EAs or indicators, a script will be launched for execution immediately after it has been attached to a symbol window, without waiting for a new tick. The entire code of the script will be executed once. After all program lines have been executed, the script finishes its operations and is unloaded from the symbol window.
