Different broking houses apply the rules differently in regards to how far you can place a trade away from last traded price. You may already know this - All platforms offer rather than a limit order you could apply a conditional order that says if FRE trades volume greater than 100,000 at 13 place sell XX units at 13.5 for example. Costs a few extra bucks. You place volume limit to prevent someone just walking the price up pip by pip feeling out for volume and only bidding 1 share . You order remains hidden from market until all your conditions are met and then goes in the market depth once triggered. You can have a 2nd conditional after that etc etc based on if it is executed etc That is the only downside that unlike now where you would be first sell order in depth at that price by the time market price has moved to your trigger others may have put orders directly in the trading depth and you will be waiting for them to be executed.

Also look at trailing orders as that may be a option to lock in profits - effectively over xx volume place order xx pips below market or xx pips from prervious day high / low and leave in place trailing last traded price by xx pips. Ie the order ratchets up for example and never comes down and for a small extra fee it can yield increased return on a trade and saves you having to manually adjust your sell / buy orders in market. .

Like with everything when using a new order strategy check how your Brokers tool works , understand it and obviously read the fine print to make sure you understand triggers just how and when a order will be seen in depth and when it will be executed.
