求翻译：当然，不要忘记，如果股票价格上涨而不是下跌，你将必须以较高的价格补进股票，因而损失卖出价和补进价之间的差额。所以，卖空的做法可能是很危险的。是什么意思？

Of course , do not forget , if the stock price rises rather than falls, you will have a higher up into the stock price , and therefore the loss of the difference between the selling price and the purchase price up .

Of course, we must not forget that if the stock price increases, rather than decreases, you will be at a higher price premium for stocks, and to the loss sell at a price and the price gap. Therefore, selling practices may be very dangerous.

Certainly, do not have to forget, but if the stock rise in price will not be falls, you will have to make up the stock by the high price, thus the loss selling rate and will make up between the price the difference.Therefore, the oversell procedure is possibly very dangerous.

Of course, do not forget that if the stock price rises rather than falls, you will have to cover stock at a higher price, thus the losses for the difference between the selling price and cover price. So, short selling practices can be very dangerous.
