How many contracts can you trade on a $50k prop account?

Less than the account size suggests. On a prop account, the money you can actually lose is the drawdown, not the balance.

The number that matters

A $50,000 evaluation with a $2,000 drawdown puts $2,000 at risk, not $50,000. Size against the $50,000 and the percentages mislead you:

0.5% of $50,000 = $250 a trade $250 of $2,000 = 12.5% of it

Eight full losses in a row and the account is gone. That happens to good traders.

Work it out in three steps

  1. Pick how many full losses you want to survive. Say 10. $2,000 / 10 = $200 a trade.
  2. Price one contract at your stop. Points × dollars per point.
  3. Divide and round down. Never up.

Worked examples at $200 a trade

MNQ, 20-pt stop: $40 each → 5 MNQ, 40-pt stop: $80 each → 2 MES, 8-pt stop: $40 each → 5 NQ, 20-pt stop: $400 each → 0

NQ comes out at zero. When one contract at your normal stop is over budget, the answer is micros, not a tighter stop you wouldn’t otherwise use.

Then check the three caps

  • The firm’s contract limit. Every account has a maximum. Your number can be lower; it can’t be higher.
  • The daily loss limit. If there is one, a full loss has to fit inside what is left of it today.
  • Copied accounts. Five accounts on a copier at 2 contracts is 10 contracts on the same trade. One bad trade hits all five.
