Indicator Community Enhancements

• Admin Review System: Administrators can now review, approve, reject, unpublish, and delete community indicators
• Purchase & Rating System: Users can buy indicators, leave ratings and comments
• Statistics Tracking: Purchase count, average rating, rating count, view count for each indicator

Trading Assistant Improvements
