Simultaneously holding both mini and micro futures contracts in the same account. Some prop firms restrict this, requiring traders to use only one contract type at a time.
Why It Matters
- 1Mixed contracts can affect margin requirements, risk calculations, and eligibility under prop firm rules.
- 2Using multiple contract types without permission may violate account rules or cause disqualification.
Example
- 1A trader holds a mini S&P 500 futures contract and a micro S&P 500 contract at the same time.
- 2If the firm’s rules prohibit mixed contracts, the trader could be flagged for rule violation.
Common Mistakes
- ✖Ignoring firm restrictions on mixed contracts
- ✖Failing to account for combined margin requirements
- ✖Confusing contract sizes when calculating risk
- ✖Overcomplicating trades without a clear compliance check
