There are two fields: "price stop$" and "limit price $"
Do you put 66 in both of them? What is the difference?
You know what a limit order is, right? The stop is the price the stock needs to trade through before your limit order is entered for execution.
If you put 66 in both fields, your order might or might not get filled at your limit price. I.e., if the stock drops to 60, then you won't be able to get filled at a 66 limit.
What you put in for your limit depends on what you are willing to accept for a sales price. If you don't want to hold the stock under any circumstances under 66, then a stop-limit order is probably not what you want to do.
As an example: if the stock trades at 66, both a stop-loss and a stop-limit order would be triggered. If the next trade is at 60, after that stop is hit, a stop-loss would be filled at 60, while a stop-limit (with a limit at 66) would not be filled until and unless the stock comes back up to 66 within the period the order is in effect.
