Follow the Daily trend. Only use lower timeframes to enter a trade when the Daily candle gives you the 'go' signal. If you don't get a signal, then don't trade.
I think there are two main reasons why most traders fail.
1. They are impatient, and thus they often try to make trades out of nothing.
2. They try to pick tops and bottoms when they ought to only stick to the Daily trend.
As for sideways markets. It's not necessary to trade them. There are many pairs to choose from. Surely one of those pairs is strongly trending! That's the pair to trade.

You don't know because you don't ask.
