Yepp.  But it is kinda glitchy.  It wont pop immediately after hitting the stop loss.  Feels like it gets queued up and then hangs there for a few minutes, in which case the price could have changed a great deal

A stop loss just sends an order when it hits the stop it doesn't guarantee execution which historically caused people to lose a lot more money than expected in rapid declines.
