Full position - buy all the money used for stock trading into stocks. Or the money used to speculate in futures was bought into futures contracts. The risk of a full position operation is greater.

Clear position——Sell all stocks.

Short position——When the stock price of a stock rises all the way, it is judged that the stock price will rise in the future market. The stock price fell back, so I sold the stock and wanted to buy back the sold stock at a low price. Unexpectedly, the stock price did not fall back and continued to rise. In this way, this "sell high and catch low" move is considered " "Short position".

Full position means using all the funds in the account to build a position, leaving no room for maneuver. The stock market can be full of positions without causing too much loss. However, if the margin market is full, a slight unfavorable fluctuation may cause big losses. So try not to overfill your position.
