There really is no “one best timeframe” to analyze. In order to achieve a true edge in trading it is imperative to study price action on multiple timeframes. A minimum of three timeframes (long , short and intermediate term) should be consulted before entering a stock position. For swing traders these timeframes should be 1- daily chart of 150-200 days for the long term trend recognition 2- 30 or 65 minute timeframe for 30-50 days for risk/reward determination 3- 10/5 or even 2 minute timeframe for 2-10 days to fine tune entries For daytraders the three suggested timeframes are 30/65 minute for long term trend, 10/5 minute timeframe for risk/reward determination and 2/1 minute charts for fine tuning of entry.
