Floating point invalid operation?

September 16th, 2014, 03:34 AM

Hi,

I am trying to convert some code from mq4 to Easylanguage which uses a "better" Heiken Ashi close value. The following code gives me a floating point error and I am not sure why? It plots but when a new tick comes in it gives me the error. This is with RC 9.0

Thanks in advance,

Alex

Code

value1 = ((Open+Close) * 0.5) + ((Close-Open) / (High-Low)) * AbsValue((Close-Open) * 0.5);
Plot1 (value1,"BetterHaClose");

hughesfleming,

you will run into this error when the study attempts to divide by 0. In your case when High and Low are the same your code will try to divide by zero. This produces the error message.
You can overcome this by adding a check like this and a good practice would be to set an alternative result in case High = Low.

Code

if (High-Low) <> 0 then
value1 = ((Open+Close) * 0.5) + ((Close-Open) / (High-Low)) * AbsValue((Close-Open) * 0.5)
else
value1 = your alternative in here

I'm getting the same error message with this code:

Code

inputs: Length( 14 ), XMA_Avg(14);
variables: BMP( 0 );
BMP =  ( Close - Open ) / ( High - Low );
Plot1( Average( BMP, Length ) ) ;
Plot2( XAverage(plot1, XMA_Avg));
Plot3(0);

How can I fix this? Thanks in advance.

olobay,

the solution is the same (your divisor is even the same, so you can use the same check) as described in #2 of this thread:
