When you’re basing your trading around a day trading chart and making short term trades for fast profits, it’s critical to have the best information. This suggests backing up your system with cross checks against other indicators. Sometimes these other indicators can point up circumstances or patterns that show you when a trend might be about to break. It is more of a secondary signal that attests or counters the signals that you already have. Mixed with a system that give signals of trend reversals or retracements, or the formation of new trends, it can exceedingly add to the likelihood of success of each trade.
If it confirms your original signal you can go ahead full steam. If it doesn’t, you can hold back and probably protect yourself from a losing trade. I do not need to tell you how this may add to your profits on the base line.
