In order to close a position I must see and believe the trend is getting tired.I watch the tickers.The lots (amounts) of buyers and sellers give a sign if the momentum is running out of steam or not.My position close is @235 USD where my short positions are between 235 to 240 USD.

I always use stop loss, my stop loss is 250 USD. Now I risk 15 USD to win 50 to 60 USD.

My buy back target is @180 USD.
