"OR" clause in NT strategy?

January 9th, 2015, 02:29 PM

OK, this could just be me losing my mind...it's been a while since I donned my programmer's cap, and I just can't remember....

I am coding a strategy and one of my conditions really wants an OR clause:

"if the Stoch is here and either this CCI is here or this one is, then do this."

Code

if
((Stochastics(7, 14, 3).K[2] > 80)
&&
((CCI(3)[2] > 95) OR (CCI(3)[3] > 95)))
{ action };

(not my exact code, just a simplified example of what I'm trying to do)

But, of course, NT7 doesn't like that. It doesn't like anything close to that.

Is there a form of an OR clause? You know, like one that serves as the partner/opposite of the && clause? I'm kind of starting to use a bunch of nested if/else statements in place of a simple OR, but it's getting very messy...

Thanks in advance,
Gary

In C#

&& = "and"
|| = "or"

|| Operator (C# Reference)

@shodson,

Hello,

i`m also struggling to buils conditions using || operator.

I have this line to begin with:

Code

(this.super.Values[0][1] == this.super.Values[3][1] || this.super.Values[1][1] == this.super.Values[3][1] || this.super.Values[2][1] == this.super.Values[3][1])

that one i need for the Bar[1] to compare the equality of either of two :

this.super.Values[0][1]

this.super.Values[1][1]

this.super.Values[2][1]

to this one:

this.super.Values[3][1]

Now for the Bar[0] i need to know which set was greater or less(< or >) to the this.super.Values[3][1]

I try this:

&& this.super.Values[3][0] > (this.super.Values[0][0] || this.super.Values[0][1] || this.super.Values[0][2])

But,get compile error that says "Operator || cannot be applied to ''double"....

Can you please suggets a corrcet way to get those conditions,please?

|| is a boolean operator. It ORs two boolean expressions like true OR false OR true

you have align your logic into boolean expressions and to think of it like this:

Code

the sky is white OR the sky is blue OR the sky is black

not

Code

the sky is (white OR blue OR black)

because the things between the ORs are not boolean expressions, they are colors

so what you need to do is

Code

&& (this.super.Values[3][0] > this.super.Values[0][0] ||
    this.super.Values[3][0] > this.super.Values[0][1] ||
    this.super.Values[3][0] > this.super.Values[0][2])

Seems working that way.

Thank you,sir!Appreciate your help and effort.

Have a fantastic weekend!

@shodson,

a little problem here.

Now that i have those conditions for the entry in place:

Code

If (this.super.Values[0][1] == this.super.Values[3][1] || this.super.Values[1][1] == this.super.Values[3][1] || this.super.Values[2][1] == this.super.Values[3][1])

&& (this.super.Values[3][0] > this.super.Values[0][0] ||  this.super.Values[3][0] > this.super.Values[0][1] || this.super.Values[3][0] > this.super.Values[0][2])

i often have the issue,depicted on the image attached.Could you please take a look and suggest what is happening?

Thank you!

It's hard for me to say what's wrong without seeing the entire code and knowing what the rules of the strategy are. I suggest you look for more significant help here or here. You really need more Ninjascript/C# programming training and experience.

@shodson,

and yet,it`s still not what i wanted.Sorry if i didn`t put it clear.

For the Bar[0], i need EXACTLY the comparison - <or> ,for the this.super.Values[3][0] and the ONE,that this exact this.super.Values[3][0] was matched at the Bar[1].For now,the conditions you`ve added just do an arbitrary comparison - which one is grater/lesser another,not for the particular set.
