We talk a lot about trading in the direction of the trend on the 4-hour chart. That is still one of the key elements of successful trading. It is not only important to follow the trend but you should be aware of a strong trend vs. a weak trend. This can be accomplished in part by timing an entry into the market.
The first thing is to determine the target time frame and trigger time frame. This means if you cannot find a trend on the 4-hour chart then look for a trend on a 1-hour chart. If the 1-hour chart is moving side ways then look at a smaller time frame until you find a trend. Once a trend is found then you have a target time frame. Watch a smaller time frame until it starts to turn in the direction of the larger target time frame. Once the signals are given that the smaller time frame is turning in the direction of the target time frame it is time to pull the trigger on a trade.
There are successful trades made by just watching the target time frame. The drawdowns can be larger by only trading on one time frame. The profits come more quickly when timing the entry of a trade.
With practice, target and trigger time frames can be spot. For longer term or position trades the weekly and daily charts may be the best charts to use. For Swing traders the 4-hour is good. For day trading the 15-minute time frame can be the target time frame and the 5-minute the trigger time frame. The currency market gives many opportunities for the position, swing and day trader.
Figure out which type of trader you are and time your entries for low stress trading. Wait for the trades to come to you. Successful trading can be done during slow times of the day by using the timing technique.
