I'm having a brain cramp here. Someone asked me this the other day and I couldn't remember the answer: Does the price of a stock have to actually have hit your price for the stop to be activated? I'm thinking no if it's a stop-market order, but I just want to be sure. For example, say you're long a stock at $10. You place a stop MARKET order at 9. The stock gets halted and opens up at 8. Would your stop be activated?
