Look up the syntax for addcolumn() in the Users Guide and note how the format parameter is used.

Subject: [amibroker] Incorrect rounding in Amibroker

Dear friends,
 
Amibroker seems to be rounding the results different than it should be. Below is a piece of the results.
The prices have two digits after dot. (h+l)/2 sometimes has 2 digits, sometimes 3 after dot.
 
Amibroker sometimes rounds the result up, sometimes down.
 
Ticker Date/Time H L (h+l)/2
Excel Calc.		 (h+l)/2
Amibroker Calc.

I may also send you the complete data if needed. You may also see easily with your own data with the following code:
 

MP= (H+L)/2;

Filter=1;

AddColumn

(H,"H");

AddColumn

(L,"L");

AddColumn

(mp,"mp");

 

Thanks in advance for your help.
