Whose SL-M order trigger first

If Someone bought an stock or option at 100 and his stoploss is at 98 and there are many ppls with same stop, whose will trigger first. Is it based on order time or something else

Hi Nandha,

The exchanges are open to a lot of investors/traders/speculators, so the orders that go to the exchange is based on price and time priority, so if there are other people who had placed the order at the same price as you, but before you, their orders will get executed first and you will move up the queue.
