An evaluation is a simulated test of whether a participant can reach a stated gain on a demo balance without breaching the loss limits attached to that balance. The structure exists because the firm cannot observe the participant's method directly; it can only observe outcomes against fixed constraints. A phase is therefore a bounded window in which two things are measured at once: whether the profit target is met, and whether the daily and overall drawdown limits stay intact throughout. A phase ends in one of three ways — target reached, limit breached, or, where a time constraint applies, the window closes.
A single-phase evaluation asks for one target under one set of limits. A two-phase evaluation splits the same assessment: the first phase asks for a larger gain, the second usually asks for a smaller one, while the drawdown limits stay the same in both. The reasoning is that the first phase tests whether the participant can produce a result at all, and the second tests whether that result was repeatable rather than a single fortunate sequence. Because the second phase is about consistency rather than magnitude, the target is reduced but the discipline required is not — the same daily loss rule and the same maximum drawdown end the account in phase two exactly as they would in phase one.
A shorter structure is not automatically a lighter one. Single-phase evaluations frequently carry tighter drawdown limits, stricter consistency rules, or a higher target relative to the permitted loss, because the firm is compressing two filters into one. The relevant comparison is the ratio between the target and the available loss room, not the number of phases.
What changes for the participant is elapsed time and the number of separate windows in which a breach can occur. A two-phase route requires clearing two gates; each gate is an independent opportunity to breach. What does not change is the nature of the limits themselves, which apply continuously in every phase, and the fact that the account is simulated throughout. Fee structures, reset terms and post-evaluation conditions vary independently of phase count, so the phase count alone does not describe the cost or the constraint set — those appear in the tables.
