A time frame is the main parameter of the chart, which helps to better understand what is happening in the market. It means the time interval covered by each candle or bar on the Japanese candlestick, bar, and Heiken Ashi charts. For example, if you monitor a Japanese candlestick chart and set a 1-minute time frame, each candle will represent the price dynamics in 1 minute. If you analyze a line chart, the time frame shows the period of time displayed in the chart window.
You can set the time frame you need in the time frame selection menu. Several time frames can be used with the Japanese candlestick, bar, and Heiken Ashi charts: 15 seconds, 1 minute, 5 minutes, 10 minutes, 15 minutes, 30 minutes, 1 hour, 4 hours, 1 day, 7 days, 1 month. You can change periods on the line chart by zooming using the "+" (plus) and "-" (minus) buttons.
Short-term traders tend to use short periods of up to 1 hour. Long-term investors analyze charts on 4-hour and higher time frames when making their forecasts.
