It goes something like this, try it out.


No, you don't understand the task.

You need to pass either the variable name or the value of the variable, depending on the situation.

 

Can one variable be assigned to several values?


something like this

int N=(1;2;5;9;15;19)

 
abeiks:

Is it possible to can a single variable be assigned to to a single variable?


something like this

int N=(1;2;5;9;15;19)

And then how do I figure out which value to use?

Or did you mean to declare an array? Then int N[6] = {1, 2, 5, 9, 15, 19};

I don't use such arrays, if I'm wrong, I'll be corrected by a knowledgeable person...

Thanks! I'm thinking to use this in tests as a restriction trade on certain days of the month. if(Day()==N[6]) !

 

Hello! Please help me...

How can you create a box on a graph, in which you can place a segment of the same graph, knowing the start and end times of the segment.

Thank you...

 

Hello, can you help me add a martingale advisor, so that in case of a losing trade, the next one will open with double lot compared to the previous one.

Please advise - there are two custom indicators, both are histogram indicators, both are displayed in a separate window. I think there is no code for this indicator. I think there may be a template (skeleton) in which we can paste the names of indicators or their codes to get an indicator showing their division (fraction). Anybody know anything?

int N[6] = {1, 2, 5, 9, 15, 19};

if(Day()==N[6])!

However, this suggestion did not work - array out of range. ..Testing pass stopped due to acritical error in the EA.

If you read a little bit about arrays, you would understand that indexing of arrays starts with zero and goes up to dimension-1, i.e. in your case from 0 to 5.

int N[5] = {1, 2, 5, 9, 15, 19} - too many initializers
