Position limits

From MarketsWiki

Position limits are the predetermined position level (number of contracts allowable for holding) set by regulatory bodies -- such as the Securities and Exchange Commission and the Commodity Futures Trading Commission -- for a specific futures or options contract. Each option and futures contract will have varying position limits.

Position limits are created for the purpose of maintaining stable and fair markets. Contracts held by one individual investor with different brokers may be combined in order to gauge accurately the level of control held by one party.
