Pavel Kolchin: very little information, or very limited functionality?how can I offer the user a set of input parameters more flexibly?for example, I need if the user selects p1 = true, then allow to specify p2 and p3 and p4, if the user selects p1 = false, then prohibit filling in other fieldsWhy iRead more
Why in input?
Just set global variables and subtract data from your file.

Write what you want to do (for how long to set the order)?
A value of 10 means that this symbol supports 2 types of expiration
SYMBOL_EXPIRATION_DAY and SYMBOL_EXPIRATION_SPECIFIED_DAY
Added
Ie EXPIRATION_SPECIFIED_DAY You can place an order before the first clearing on the day you set,
and SYMBOL_EXPIRATION_DAY – to the nearest clearing

a18psrock: Hello, I have been developing robots on MQL5 for a long time. I want to move some of my robes to QUICK. I don't like this platform at all and have never written for it. How to start learning? Are there any professionals here who also program for QUICK and were engaged in translating expeRead more
Give up this idea, because even if you write something on QLUA, you will not be able to test it.
The only way out is data output via the DDE server and transactions via trans2quik.dll

Fredrixon: Hello, good people. I'm a complete beginner in writing robots, but I'm a bit of a trader and now I want to robotize my strategy. I don't want to hire freelancers, but I need to get into this kitchen of programmers myself. Can you tell me what language I should learn?(mql4 or mql5) In whatRead more
It’s very simple.
Every programming language has procedures and functions.
Procedures do not return anything, but simply perform a set of any operations,
and functions return the results of operations. A program (adviser) consists of a set of procedures and functions.
An example of a function:
int TestFunction(const int param_1, const int param_2 ){
return(param_1+param_2);
}
Sample procedure:
void TestProcedure(){
c=a+b;
}
Both functions and procedures are passed parameters that can be operated on
procedures and functions. Parameters can be return values.
They can be returned by both functions and procedures.
You just need to learn the syntax of the language and the types of variables.

Aliaksandr Hryshyn: I wonder how you control the operation of the strategy in the expert Advisor, I mean program control in the expert Advisor itself.TS is the algorithm that the expert Advisor uses, as "you will harness, so you will go".
