Or conditional

[Faspomy]

if (CrossAbove|CrossBelow(blahblah))
{
do this
}


I receive the following error;
"Operator "|" cannot be aplied to the operands of type 'method group' and 'bool'. CS0019


Is there any other way to ensure that, when a value crosses a certain point (travelling either up or down), that either way it triggers a condition ?

"or" operator in NinjaScript/C# would be '||' and not '|'.

"and" operator would be "&&".

Dierk,

thank you. Sorry for that error-- I was programming late (2:30AM here).


I tried '||', and still receive the same error.

I can't really use >= or <= or < or > for this Strategy, since it contains many values which must be kept separate.


Or, does '==' work if a bar contains that value (if open and close are not exactly equal to that value) ? For example; open is .8112 and close is .8124. Will an "if (value== .8120)" work ?

the logical or "||" should work for what you're doing. I'm sure after using || rather than | you receive a different error message; what does it say now.

In addition, "==" will work for the logical comparison you're attempting with value == .8120

To reiterate logical statements
x < y means "If X is Less Than Y"
x <= y means "If X is Less Than or Equal to Y"
x > y means "If Y is Less Than X"
x >= y means "If Y is Less Than or Equal to X"
x == y means "If X is Equal to Y"

x = y means set X to Y value

BitWise logical statements
x | y
x & y
Both of these would be used generally for masking or something to that affect. They are usually cryptic, and can be written out with a bit more to make more sense. I don't recommend using them.

Hope this helps.

Mr Logik,

Thank you for the information.

The error is actually the same using '||' as using '|'. I will try '==' for this strategy.

[mrlogik]

if you can please post the line of code which is causing the error.

if (CrossAbove|CrossBelow(blahblah))

Your attempt to call CrossAbove is missing the parenthesis and parameters. You need to call it like using something closer to this, so NT knows what indicators are supposed to be crossing and how far back to look:

CrossAbove(EMA(ShortPeriod), EMA(LongPeriod), 1)

[Faspomy]

just an example;

     if (CrossAbove||CrossBelow(High, Open, 1))
            {
                EnterLong(1,"");
            } 

I receive the same error no matter what I place into the (XX, XX, 1) brackets. '1' signifies the lookback period. Other than that, I receive an error regarding the use of '||' every time.


EDIT; when I change the code to 'CrossAbove' or 'CrossBelow' (without "||"), the strategy compiles without issue.

Faspomy try it like this.

if (CrossAbove(High, Open, 1) || CrossBelow(High, Open, 1))
{
     EnterLong(1, "");
}

Perfect Josh !

Thank you.
