Option Trading Algorithm IB Script

US stock/options stop loss script on To clarify: not p&l of account instead, but in individuals trades. for example if i were to enter an aapl call position each contracts that cost 4.00 per contract. And i want the stop loss variable to be activated at specifically at -13%. So when that contract is value 3.48 (which is -13%) i want it automatically to be thrown into the bid. I understand there will be slippage. I will accept that but the idea is risk management and exit trade completely.
