      Because of the uptick rule, getting short is harder to do than goinglong. When you find a short opportunity that is available through yourbroker, you will need to anticipate the top, and get in early. Many timesyou will wind up getting short before the top, and will have to withstandlarger movements against your entry point in order to capitalize on theanticipated movement. You should pick a maximum loss that you are willingto withstand before calling it quits and exiting the position. As a rule ofthumb, this level should be greater than the maximum loss that you arewilling to withstand in long positions, given the nature of short trading.
