Why do round numbers matter in trading?

Round numbers are common psychological anchor points where traders place stops, targets, and mental exit levels, whether or not that level matches the trade's actual technical structure. Tracking how often your exits cluster at round numbers can reveal whether your exits are plan-driven or anchor-driven.

How often am I exiting at round numbers instead of my planned price?

Q: How often am I exiting at round numbers instead of my planned price?

Log your planned exit price against your actual exit price for each trade. The tracker flags any actual exit ending in .00 or .50 as a round-number exit and totals the cost of deviating from your plan across all logged trades.

The traders who last aren't the ones who never lose. They're the ones who never guess.

How this is calculated

A round-number exit is flagged whenever your actual exit price ends in .00 or .50, a well-documented anchor point where traders tend to place mental exit targets regardless of what the trade's actual structure calls for.
Deviation cost for a long trade equals your planned exit price minus your actual exit price, multiplied by shares. A positive number means you exited worse than planned. For a short trade, it's your actual exit minus your planned exit, multiplied by shares.
A single round-number exit isn't automatically a mistake, sometimes a round number and your actual planned level genuinely line up. What matters is whether a pattern shows up: consistently exiting at round numbers that are worse than the level your plan called for.
