How do prop firms afford to pay funded traders?

The arithmetic works like insurance:

• Many traders pay fees.
• A smaller group passes.
• A smaller group again withdraws profit.
• The fees from the whole group fund the payouts of the successful few.

This only works if the assumptions are realistic. Problems start when rules are loosened for marketing, when a promotion sells many cheap challenges, or when a group of traders uses an abusive strategy that passes more often than skill alone would. A reserve covers the gap between expected and actual payouts.

Accurate rule enforcement protects the model. If loss limits are checked late, traders can lose past them and still dispute the breach, or exploit gaps between checks. PropExecutor evaluates each account's rules on every price tick as it arrives, so limits hold at the moment they are crossed.

The role of the reserve

Revenue and payouts do not arrive at the same time. A reserve held separately bridges the gap, so a strong month for traders never depends on that month's sales.
