For the Z9 trading system (here:
https://zorro-trader.com/manual/en/zsystems.htm ), there's a equities chart (screenshot below)
![[Linked Image]](https://zorro-trader.com/manual/images/z9perf.png)
The equities chart, blue bars, show drops in equity, but the drawdown red bars doesn't match the drops in equity.
Why is that happening? I expect the red bars to show the drawdowns when the blue bars decrease.
Thanks!
