I want to declare a variable

[Jah Luv]

I just want to do a simple thing that can be easily done in any programming language. I want to declare a variable, for example

def Val = 0;

and then I want to, further down, increment it. You'd think that

Val = Val + 1;

would do it but it doesn't. Can somebody help out.

Thanks in advance.

It may sound simple, but its not.

The biggest obstacle between traditional programming languages and thinkscript is the iterated nature of the language. ThinkScript is iterated on a bar by bar basis, and each variable is an array of sorts. This would depend on whether you're trying to increment the variable on the same iteration, or among different iterations.

Among different iterations, it would be

def Val = Val[1] + 1;

However, it can not be incremented within the same iteration. This is not to say that it can not be done, just that the structure of how this could be accomplished is different than what you might be used to. I could show you more easily if you could give me a more fleshed out version of what you're trying to accomplish.

Thanks for responding. I guess I could. Let's say

def out1 = (ohlc4>EMA1);

and then

out1 = out1 + (EMA1>EMA1[1])

If thinkscript accepted variable reassignment, which unfortunately it doesn't, that would result in a 2 if both Boolean expressions returned True.

Are you trying to tabulate some type of score?

If so, it would be:

def out1 = (ohlc4>EMA1) + (EMA1>EMA1[1]);

If just you're trying to determine whether or not both are true, it would be:

def out1 = (ohlc4>EMA1) and (EMA1>EMA1[1]);

This results in a single Boolean value.

You may still need to be more specific.
