Here's a suggested time frame for trade confirmation for different types of traders:

Swing Traders:
Primary Time Frame: 4 hours
Secondary Time Frame: 15 minutes
Swing traders typically hold positions for several days to weeks, aiming to capture larger price movements. The primary time frame of 4 hours allows them to analyze the broader market trends and identify potential swing trading opportunities. The secondary time frame of 15 minutes provides a closer look at the price action for entry and exit points.

Day Traders:
Primary Time Frame: 15 minutes
Secondary Time Frame: 5 minutes
Day traders aim to enter and exit positions within a single trading day, capitalizing on short-term price fluctuations. The primary time frame of 15 minutes helps them identify intraday trends and setup their trades accordingly. The secondary time frame of 5 minutes provides more detailed information for precise entry and exit timing.

Scalpers:
Primary Time Frame: 5 minutes
Secondary Time Frames: 3 minutes or 1 minute
Scalpers focus on extremely short-term trades, often holding positions for just a few seconds to minutes. The primary time frame of 5 minutes allows them to spot quick price movements and identify potential scalp opportunities. For even more granular analysis, some scalpers may use secondary time frames of 3 minutes or 1 minute to fine-tune their entry and exit points.

Keep in mind that these suggested time frames are not set in stone and can vary based on individual trading strategies and preferences. Traders should always adapt their time frames based on their own analysis and risk management techniques.
