Chart type
Most common: candlestick (OHLC), line (close only), bar (OHLC). Heikin-Ashi smooths for trend clarity.
Candlestick is default for good reason - it encodes OHLC + direction at a glance. Line charts hide intraday info. Heikin-Ashi paints trends that didn't actually happen - use for bias confirmation, never for entries.
