The time frame for scalping in forex can be short and range from one minute to fifteen minutes. Traders generally deploy technical indicators of shorter duration to make the indicator more responsive. Most traders, however, prefer the range between 1 minute and 5 minutes for scalping in the forex market. Cutting down on the duration ensures that the trader is not exposed to higher volatility in these markets. Generally, scalping using short-duration timeframes works well for liquid currency pairs like EUR/USD and GBP/USD.
