Comparing Strings or Formatting Ints

[setardiff]

*ignore the title, they are not ints I'm looking to format.

I'm working on a strategy and I have two questions.

First, I'm trying to figure out how to compare two different strings.

As of now, I have:

string1 == string2

which results as a bool and works properly, but I would like to know if string1 is greater/less than string2. The values are converted into strings because I am looking to retrieve a number with 0.00 formatting and that was the only way I know how to. So maybe my problems could be solved with some kind of decimal formatting that I'm missing.

Secondly, I would like for string2 (if possible) to be a range of numbers. For instance, 0.00 - 0.20.

So ultimately, I would like to know if something like this:

string1 < (0.00 through 0.20)

is possible or even something like:

string1 > 0.00
&& string1 < 0.20


Here is the specific line, if it makes a difference:

((((((((Close[0] - Low[1])*4)+8)*RiskReward))/35).ToString("F2")) == 0.20.ToString("F2"))


I'm very much a beginner if you couldn't tell.
Thanks in advance.

Hello setardiff,

To round a number to a certain decimal place you can use Math.Round(yourNumber, 2)

It is not possible to compare strings as numbers without converting them into numbers, if the value started as a number its better to just round it as a number and then compare it as a number.

To make a condition that is a range of numbers you would need to use 2 conditions checking if the value is greater or equal to the lower value and less or equal to the greater value.

Thanks Jesse.

When I try:

((((((((Close[0] - Low[1])*4)+8)*RiskReward))/StopLoss))) > .2;

I get another cs0019 error, saying '>' cannot be applied to type 'void' and 'double'.

Is there a way to convert 'void' to 'double' or is there another way to achieve a comparison of these two values?
I'm assuming I can use Math.Round once I figure out the appropriate values.

Thanks again.

Hello setardiff,

From this code I don't see that you are using a void. Are you certain that is the line having the error? Void is a method that does not return a value.

Its likely best if you simplify the code into individual values and then do a comparison as the last step, for example:

double unrounded = ((((((((Close[0] - Low[1])*4)+8)*RiskReward))/StopLoss)));
double rounded = Math.Round(unrounded, 2);
bool isTrue = rounded > .2;

[setardiff]

Yes, I am certain that line was the problem, as it was highlighted when double clicking the error code.

As stated, I'm very much a beginner. so forgive me for these seemingly simple questions.

To clarify, I put:

double unrounded = ((((((((Close[0] - Low[1])*4)+8)*RiskReward))/StopLoss)));
double rounded = Math.Round(unrounded, 2);

in the DataLoaded section and use:

bool isTrue = rounded > .2;

as the comparison within the OnBarUpdate/conditions section?

I tried that and am attempting to Print (bool isTrue = rounded > .2); within the actions and it will not compile.

I assume I am just misplacing these lines.

I appreciate your help.

Hello setardiff,

That code cannot go in State.DataLoaded, bars have not processed in DataLoaded. To use bar data you need to put that code inside OnBarUpdate. All 3 lines would go in OnBarUpdate.

All set, thanks again, much appreciated.
