Question About "If" and "else if"

[GLFX005]

Hello Staff,

I am puzzled when trying to understand the concept of "If" and "else if".
To do this correctly, do I need to place both the "If" and "else if" in the same bracket like this?

{
if (X=true)
{
//Do Something
}
else if (X=false)
{
//Do Something Else
}
}

Or will the "else if" work with whichever "if" is placed above it no matter the brackets, and ignore the "if" that is placed below it?

I'm looking forward to your reply.

Hello GLFX005,

Try the following:

bool myBoolA = false;
bool myBoolB = true;

if (myBoolA == true)
{
Print("myBoolA is true");
}
else if (myBoolB == true)
{
Print("myBoolB is true");
}

The curly braces outside of the if statement (branching command) would be related to another object such as the method the if statement is in, or if this is nested in another if statement.
In the code you have suggested, the outer brackets would nothing at all as there is no method declaration or if statement above it.

This would fall under general C# education and is not specific to NinjaTrader.

Hello Chelsea, thank you for your answer.

Is the "else if" ignored when the "if" above it is true?

Hello GLFX005,

That is correct. When the 'if' is true, the 'else' will not be evaluated. The 'else' means that the first 'if' didn't happen similar to using the english word otherwise.

As an example if you were to say to someone if you have a red ball i would like to buy it, else if you have a green ball i'll buy that.
