Januson Function Library · **Released**: 11-28-2008

This is a collection of small and usefull functions from my library. I'll just post them as I write or review old ones

I'm using MultiCharts, but I'm almost sure that tradestation users can compile them without any problems as both supports EasyLanguage.

************************* **
Function: JK_Math_RoundToNearest
Just a small function from my library. I've discovered that RangeBars can give some funny open and closing values that needs to be comformed correct in order to write a pattern recognizer.

Code:

//FunctionName: JK_Math_RoundToNearest 
//Summary: A small function invented for rounding numbers to nearest precision i.e. round 100.27 to 100.25 or 95.86 to 95.75
//Author: Januson Nov2008, rev.0

//Example: JK_Math_RoundToNearest(100.58, 0.25) -> 100.50

 inputs:
 	valueToRound(NumericSimple),
 	nearestFraction(NumericSimple);
 	
 
begin
 
var:
 	double PRECISION(10000); //constant
 	

 	
 	JK_Math_RoundToNearest = IntPortion(valueToRound) + (round((fracportion(valueToRound)* PRECISION) /(nearestFraction * PRECISION), 0) * (nearestFraction * PRECISION))/PRECISION;
 	
end;

Bump: When I develop indicators I need to have quick and easy access to debug information, i.e. Why is this value that at this point? I therefore insert JK_BarDateTime in the if-then or other points of interest.

Example from indicator:
if condition1 and condition5 then
begin
... yada yada
print(JK_BarDateTime, condition1, valueXX);
end;

I can then use the output window to track debug info quite easily

Code:

//FunctionName: JK_BarDateTime
//Summary: A function to convert the EasyLanguage datetime information from current bar
//Author: Januson Oct2008, rev.0

//Example: Print(JK_BarDateTime);

JK_BarDateTime = DateTimeToString(datetojulian(date) + ELTimeToDateTime_s(Time_s)) ;
