Let's say I have Option A that I want to buy at $1.10 ($110). I want to either sell it for 100% gain at $2.20 at the minimum, or let it expire worthless. In order to do this, I would want a trailing stop order to automatically trigger once this option reaches a price of $2.20 (and have no stop loss until then), say we could put it at 5% below the current market price (of $2.20) to protect our potential loss after a 100% gain and let profits ride. How would I go about setting this up? Currently prefer/am on ThinkOrSwim, but if it can't do it, I'll go to any platform that can execute this type of order.
