A High Time Frame refers to any time frame above 12 hours and is commonly utilized by Swing Traders. Trades based on these higher time frames can last anywhere from a week to months, depending on the strength of the underlying trend and the specific Trade Plan implemented by the trader.
Moreover, evaluating a trade on a Higher Time Frame than your Trigger Time Frame (TTF) when analyzing trades is always recommended. For instance, if you are examining a Breakout Trade setup on the 4-hour time frame, it is also advisable to check the 12-hour and Daily time frames. This helps to ensure that there are no technical reasons not to take the trade that was not easily identified in the 4-hour time frame.
