This script distinguishes up/down volume based on lower resolution.
It's important to set correct input "Detailed Resolution" — it affects detalization/loading speed. If equal to chart resolution, should match builtin "volume". The lower it is, the more detalized up/down border.

added `lookahead=true`, because sum was one bar off,
rewrite slow loop, 100ms error should disappear.
リリースノート
`lookahead=false` was correct. But there may still be some weird bug in some cases.
リリースノート
added another style of border between up and down volume (PlusMinus),
fixed some errors (mismatches in volume), like on the first bar of the day,
added option to autofix or highlight any mismatches in volume,
show separate up/down sma's and removed input 'show ma', use styles if needed.
