Yes, once your order got activated. Before that just your Broker who can see it or exactly if you prefer your Broker's computer, not your Broker's personnel. Market Maker has no interest to see trailing stops order in the queue.
Any expert who can confirm the above statement is not true? I'm interest to know as well.
To clarify my question, I'm not talking about putting in a normal stop, I know these can be seen. I'm talking about some brokers have a feature now where you set a trailing stop, for example .50 cents under the rising stock price. Basically set it and forget it, check if it got filled at the end of day.
