I see an error in chart legend after applying an indicator or a strategy

• I see 'Order's limit (9000) was reached' error
• I see 'The study has too many output series' error
• I see 'Calculation takes too long to execute' error
• I see 'Pine cannot determine the referencing length of a series. Try using max_bars_back' error
• I see 'Memory limits exceeded. The study allocates X times more than allowed' error
• I see ‘Max depth of child study reached’ error
