open
The first price of a candle: where price started when that stretch of time began.
The fuller meaning
The first traded price of a period. A candle's colour compares its close with its own open; the session open often brings a gap from the previous close and the busiest, jumpiest trading, so many traders note the opening gap before trading.
open, also called opening price.
