Feeling grim

Felt like a touch of 'flu this morning so entered a trade and went back to bed!
Trade was a combo and not thinking straight but eager not to miss out after a few misses recently, I took the trade for a credit of 2 and market dropped enough for me to close out for credit of 4, so no damage done.
Trade was -sell 4450 call buy 4150 put- a combo known as risk reversal or 'synthetic short' (mentioned that before and it sounds like that awful cycling gear).
Here's the painful bit -could have entered the trade at R1,( for credit of 10 or more) even though price went through it, and closed out for about 6, so could have made 16.
We fight to live another day. (joke!)
