The selection of right time frame for day trading (Intraday) is a very subjective question and is frequently asked by the novice traders. The selection of the time frame depends on many parameters. But according to my experience it depends on mainly two parameters.
1. Stoploss
2. Signal strength of your trading strategy.
The time frame from 1 minute to 1 hour is best for day trading. Let us discuss these parameters in detail.
1. Stoploss: Each time frame has a different stoploss level. The higher time frame has a deep stoploss level as compared to the lower time frame. So, we have to select the time frame according to the stoploss or we can say that the right time frame depends on the amount of money you afford to lose in one trade. Before entering into the trade, check the stoploss for different time frames and then choose the time frame according to the bearable amount of money to lose in one trade.
2. Signal strength of your trading strategy: Whatever strategy you choose to trade, the entry and exit signals are always strong on the higher time frame as compared to the lower time frame because the lower time frames has high volatility as compared to the higher time frames. It means the success rate is high on the higher time frames as compared to the lower time frames.
Both of these parameters are directly proportional to each other. So, the selection of the time frame for day trading must depend on both of these parameters. We have to select the time frame on which our signal strength is good and also the comfortable amount of money which we afford to lose in one trade.
