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.

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. Ilhan
