Consistency
Consistency evaluates whether results repeated through time instead of relying on a few rare jumps.
Consistency looks at monthly regularity and dispersion of monthly returns. The idea is simple: two accounts can reach similar total return, but one does it through a smoother series while the other gets there through chaotic jumps.
A high score means profitable months appear often and the monthly curve is not too jagged. A low score means the result may depend on isolated months and repeatability is still weak. This metric does not require every month to be profitable; it looks for stability, not a perfect line.
Example: Consistency 78/100 means 8 of 10 non-zero months were profitable and return dispersion was moderate. Consistency 34/100 means only 4 of 10 months were profitable or monthly results were too unstable, even if the total result is positive.
How we compute it
We take the share of profitable non-zero months and map it to 0-100: around 40% profitable months is near the low end, around 90% near the high end. If monthly TWR returns are too unstable, a separate penalty is applied.
