Maximum Position
Maximum position is the largest total exposure, measured in contracts, lots, or notional value, that a trader may hold open at one time on an evaluation or funded account. The cap applies across all open positions combined, not per trade, and is fixed to the account size or instrument chosen at signup.
Why it matters
The cap limits how much risk a trader can stack up at any single moment, which protects the firm's capital and keeps the trader's own evaluation from being wiped out by one oversized bet. Orders that would breach the limit are generally rejected automatically rather than logged as a violation, so knowing the cap in advance saves wasted order attempts and confusion during fast markets.

Example
On a futures evaluation, a firm might allow a fixed number of standard contracts, or a larger number of micro contracts, applied across every instrument combined. A trader holding contracts in one product reduces what's available elsewhere: 2 contracts in one index future plus 4 in another could use the full allowance, or the same exposure could be split as a mix of micros and standards using a fixed equivalency (commonly ten micros to one standard). Some firms instead cap exposure per instrument by notional value, so a smaller number of contracts in an expensive instrument can hit the ceiling faster than a larger number in a cheaper one.
Common misconception
Traders often assume that splitting one intended position across several instruments or firing off quick successive orders lets them dodge the cap. Firms calculate exposure across all open positions combined, so chained orders adding up to more than the allowed total are simply rejected, not executed as a workaround. Genuine scaling into a position over time is normally fine, but only when it reflects real trade management rather than an attempt to exceed the fixed limit by stealth.
