Multiple Moving Averages [clean]

Very simple indicator script to display multiple simple moving averages. I know others have made this but they often are too feature-rich and can get cluttered.
Can optionally show a cross when MA 1 crosses MA 3. These are colors such that when MA 1 crosses BELOW MA 3 a red cross is shown, and green when crossing above.

릴리즈 노트:

minor tweaks for better UI. I recommend changing the visual order and bringing this to the front on most layouts.

릴리즈 노트:

- added ability to use custom resolutions for MAs (i.e. using 1 day for MA periods while viewing a chart that is set to 1 week resolution).
- cosmetic tweaks
- added comment lines to code for anyone interested
