Price of single future unit is 1000
and margin required is 100000
how can i define the point value .


Have a look at "Symbol Information" from AB's "Window" menu item - you should be able to enter the info you need to.

Also do a search in the "AmiBroker User's Guide" for "Information Window", which shows and explain how to enter the info.

If your query is more complicated than that, please follow the guidelines here:
