Although the average trader is unlikely to ever approach them, exchanges and the CFTC establish limits on the maximum speculative position that any one person can have at one time in any one futures contract. The purpose is to prevent one buyer or seller from being able to exert undue influence on the price in either the establishment or liquidation of positions. Position limits are stated in number of contracts or total units of the commodity. The easiest way to obtain the types of information just discussed is to ask your broker or other advisor to provide you with a copy of the contract specifications for the specific futures contracts you are thinking about trading. Or you can obtain the information from the exchange where the contract is traded.
