The consistency rule is one of the most misunderstood and controversial rules in prop trading. Some traders hate it, others see it as a fair measure of skill. Here is what you need to know.
What Is the Consistency Rule?
The consistency rule limits how much of your total profit can come from a single trading day. Typically, no single day can account for more than 30-40% of your total profits.
Example: If you made $5,000 total profit on a $50K account:
- With a 30% consistency rule, no single day can exceed $1,500
- If one day you made $3,000 (60% of total), you would FAIL the consistency requirement
Why It Exists
Prop firms use the consistency rule to filter out:
- Lucky one-hit traders who got a single big win on news
- Gambling behavior — all-in on one trade
- Unsustainable strategies that rely on rare events
