In depth
An AMO does not trade after hours — nothing does, in the Indian cash market — it simply queues an instruction for the morning. Because many AMOs are released into the pre-open or the first minutes, they can arrive together into a book that is still thin, and market-type AMOs are the classic way to get a bad fill on the open. Most brokers therefore restrict AMOs to limit orders. Treating an AMO as a way to trade on overnight news is a misunderstanding: the news is already in the opening auction price by the time the order arrives.
Worked example
An AMO market buy is placed at 22:00 after strong results. The pre-open auction sets the open at ₹436 against the previous close of ₹400, and the AMO fills there — 9% higher, because the auction had already priced the news.
