Hello, Yes they do start from zero, but this "zero" refers to AFL ARRAY index. AFL ARRAY by default represents VISIBLE part (i.e. SUBset) of all available data. If you use setbarsrequired you CHANGE how many quotations are in the AFL array. Specifically when you use sbrAll you say, "give me ALL quotations instead of just visible" Read this: http://www.amibroker.com/kb/2008/07/03/quickafl/
