Study the log of Zorro and compare to indicator/price values in MC; search the manual for possible explanation. If smth is not clear, then ask specific questions.

Top of mind, two possible sources of difference:
- bar construction in Zorro (how are sessions set up in MC? Weekends/incomplete weeks in Zorro) and
- Zorro's RSI is based on an exponential average while MC's RSI - on a simple average.
