The adjustment
Two accounts with identical trading show different balances, and only one is informative.
The nominal balance responds to three things: trading results, deposits, and withdrawals. Only the first of these is a statement about the system. An operator drawing income monthly and an operator compounding untouched can trade identically and arrive at different balances, and reading progress from the raw figure would attribute the difference to performance. Adjusted equity strips the capital movements out, which makes the comparison against a milestone a comparison of the thing the milestone was set to measure. The instruction is direct — read adjusted equity rather than nominal balance, because withdrawals or adjustments may alter true progress — and the word altering matters in both directions. A deposit flatters the rail exactly as much as a withdrawal penalises it, and an operator who tops the account up and reads the resulting milestone position as improvement has recorded a bank transfer as edge.
