Methods other than MAX()/MIN() and HighestBar()/LowestBar() that use regular Doubles?

[jamestrader21x]

I'm looking for a Method for MAX()/MIN(), and/or HighestBar()/LowestBar() that uses regular doubles instead of ISeries<double> or will accept both. MAX()/MIN(), and HighestBar()/LowestBar() won't let you use regular doubles. I don't have that much experience with writing methods or using for loops. Does Ninja Script have a method for MAX or Highest price that will except regular doubles? Here is an example of my code. As you can see, MAX() and HighestBar will only take a ISeries<double>


if(CurrentBar < MaxLookBack)
return;

int Multiplier = 10;

double maxRange = MAX(High, MaxLookBack)[0] - MIN(Low, MaxLookBack)[0];
double tickOffSet = TickSize * Multiplier;
double theHashLine = MAX(High, MaxLookBack)[0] - maxRange - tickOffSet;


HashLine[0] = fibLine;

double highestHash0 = MAX(theHashLine, MaxLookBack)[0]; //get an error
double highestHash1 = HighestBar(theHashLine, MaxLookBack); //get an error

Hi James, thanks for posting.

The maximum and minimum need multiple values to evaluate a number to be the maximum or minimum out of all of them. If there is only one double value then there would be nothing else to compare against. There is a discussion here about getting a max value from a List<double>:

In my example, I want to compare the highest HashLine[0] (which is an MA) vs future plots that may be lower than it. What I'm trying to code is, if future plots are lower than the highest plot, then set the current plot to price of highest plot. However, I can't use regular doubles with with MAX()/MIN(), or HighestBar()/LowestBar(). They will only take ISeries<double>. So, I didn't get that far to make a comparison. Since I don't have much experience with writing code for for loops and/or methods, I wanted to know if Ninja Script 8 has any other look back Methods that will accept regular doubles.

if(CurrentBar < MaxLookBack)
return;

int Multiplier = 10;

double maxRange = MAX(High, MaxLookBack)[0] - MIN(Low, MaxLookBack)[0];
double tickOffSet = TickSize * Multiplier;
double theHashLine = MAX(High, MaxLookBack)[0] - maxRange - tickOffSet;


HashLine[0] = fibLine;

double highestHash0 = MAX(theHashLine, MaxLookBack)[0]; //get an error
double highestHash1 = HighestBar(theHashLine, MaxLookBack); //get an error

HI James, thanks for clarifying.

You can keep track of the highest value in OnBarUpdate:

private highestDouble = -1;
OnBarUpdate:
if(newDouble > highestDouble)
highestDouble = newDouble;

Since you are waiting on future values, the min or max methods can not be used and you need to monitor and save the new values as they come in.
