Why AMO executed during PreMarket?

I had expected the AMO to be executed at 9:15AM but it executed at 9:08AM, I suffered loss as it had less liquidity.

Hi @athma_prathisti
Can you share the orderId so we can investigate this further.

Thank you!

Loss is huge as you can see

@athma_prathisti It seems your order executed in pre open session which is expected.

Please review below document for market timings

and below document for AMO timing

Hope this helps, Thanks

But other leading broker discount broker with more than 1 crore customers execute at 9:15AM, I thought it will be same across all brokers, how this differs ?
is there not a guideline from exchange or SEBI.

Hi @athma_prathisti You have placed an order in the IRCON-EQ instrument, which is a pre-open eligible as per the exchange contract file.

  • Pre-open eligible instrument in the CASH segment are triggered at 09:00 AM (Monday to Friday).
  • CASH AMO instrument that are not pre-open eligible are triggered at 09:15 AM (Monday to Friday).

ok now it makes sense where can we see the list, or how to find if a stock is Pre-Open eligible

@athma_prathisti You can check the NSE website for pre-open stocks at the following link:

But in the link that you given just shows the pre-open price, that will be applicable for all stocks, what i am interested in knowing is the pre open eligible stock where if I place the AMO order they get executed at 9:07AM instead of 9:15AM. it can gives opportunity as well as big loss.

Hi @athma_prathisti

This is interesting! Let me check if we can host a file with a list of all stocks where AMOs can be placed during pre-open sessions!
