In your subject title...you implied you shorted ES/NQ. Also, you implied you're looking for a 10% retracement (down) from the area of your Short position. Shouldn't you be able to answer your own question that explains why you Shorted the Emini futures and looking for a 10% profit target ? If you can't answer your own question, you shouldn't be trading the Emini futures.
Don't gamble; take all your savings and buy some good stock and hold it till it goes up, then sell it. If it don't go up, don't buy it. Will Rogers
