Correlation – A statistic measuring how closely the equity curve follows a straight line. In MT5, “LR Correlation” is the correlation coefficient between the balance line and its linear regression trend. Values close to 1.0 indicate a steady trend (few big drawdowns or spikes), while values near 0 imply a very jagged equity curve. It gauges consistency: a strategy with consistent incremental gains will have a higher LR correlation (smoother equity).
