Hey Teruki, sorry this went unanswered!
I think this is what you are asking for, but I can't test it quite properly as the market is closed.
StopPrice=Price;DefShare=200;Price=Ask;Route=LIMIT;TIF=DAY+;BUY=Send;TriggerOrder=RT:STOP STOPTYPE:MARKET PX:StopPrice-0 ACT:SELL STOPPRICE:StopPrice QTY:Pos TIF=DAY+;
It should allow you to place a stop where you want by clicking and allow you to buy 200 shares at the ask. Of course you can change the qty of shares and ask to bid if you'd like (in bold). Also swap the orange ones if you want to use the hotkey for shorting.
Is this what you were hoping for?
