Day traders (market scalper) watch daily, hourly, five-minute and 1-minute price charts.
Swing traders begin by first examining weekly price charts. Then they move to shorter interval charts in which each candle represents one day, one hour, and finally several minutes. Swing traders may finally examine a 15-minute chart to see what the price has done over the past few hours.
Long-term traders study the same charts that buy-and-hold stock traders use--typically the monthly, weekly, and daily charts.
