Re-read carefully. Read the computer analogy. You just said, "I'm not sure how to sell". When you short an asset, you are selling it high and buying it low. You already sold your HERO at a high price and now you must wait for BTS to appreciate in value, which has the intended effect of decreasing the value of the HERO. After this happens to a degree that is acceptable to you (your desired profit), you will be able to buy back your hero at a value less than you originally sold it for. Read through my example until it sticks. Get a whiteboard and draw pictures to help you frame it in your mind.
Glad it helped.
I managed to short two hero's. But now I am a bit stuck as I am not sure now how to sell.
