How is the correlation of the meta strategies calculated? Probably based on the equity curve, but how exact and what interval (per trade, daily, weekly, etc.)?

Correlation coefficient: when strategies get close to -1, they cancel each other out, don't they? One System - hypothetically - increases by 1%, the other falls by 1%.

Is this really "excellent diversification"? Shouldn't one aim for a correlation that is close to 0?

Equity curve, yes. It's the result of the Corr (Correlation Coefficient, CC) indicator on the entire curve in the base scale. A CC is found for each combination of strategies, summed and averaged.

Example:
Equity curves of 4 Strategies: A, B, C, D. The correlation of A to the others is:
( Corr(A, B) + Corr(A, C) + Corr(A, D) ) / 3

Thank you, @Cone

Is it a) the equity curve "as is" or b) the daily/weekly changes in the equity curve?

With a) two profitable strategies with low drawdown also have an r close to 1.0 even if the fluctuations are not correlated. (This is the ideal combination)....

a) "as is" (but synchronized) using Corr.ComputeCoeff()

A perfect negative correlation (-1) doesn't guarantee a neutral return since correlation is just directional. Example: If you buy equal dollar amounts of QQQ and QID (2x inverse of QQQ), the correlation is -1, but the return will positive if the market is trending higher.
