When Special Mode is activated (color_style = true), colors are chosen as follows:
• If the volume of the current bar is less than that of the previous bar, the color gray (#9E9E9E) is used. • If the volume is not less, but the MFI of the current bar is less than that of the previous bar, the color red (#E53935) is used. • If neither condition is met (i.e., the volume is not less, and the MFI is not less than the previous bar), the color dark green (#00897B) is used.
When Special Mode is deactivated (color_style = false), colors are assigned this way:
• If the volume of the current bar is less than that of the previous bar, then: • If the MFI of the current bar is less than that of the previous bar, the color brown (#795548) is used. • If the MFI is not less, the color blue (#03A9F4) is used. • If the volume is not less: • If the MFI of the current bar is less than that of the previous bar, the color pink (#E91E63) is used. • If the MFI is not less, the color light green (#8BC34A) is used.
I think it is gonna be more useful if you tell about the meaning of the colors for those who dont know.
