A single strategy might not give you the full information on the market price movement. But combining strategies together helps a lot.
Combining strategies and still having same results. It's a clear confirmation for trade entry. Which one strategy may lead to fake outs sometimes.
Combination of strategies is not always helpful, making a trader to become either confuse or more confident about an entry. The whole thing would be a messy if we knows every spots of the market, some certain information are just suppose to be left unknown, because for us it's good we know these projects but unknown to us that we're the causes of our losses. A trader become too confident about an entry and forget that losses exists, I only used supply and resistance zone to trap out my entry and hope for the very best when it hits my targets.
