When you are basing your trading around a day trading chart and making short term trades for fast profits, it is vital to have the best information. This means backing up your system with cross checks against other signals. One of these patterns is divergency.
Divergence isn’t in itself something a trader would base a system around. It is more of a secondary signal that confirms or challenges the signals that you already have. But don’t underestimate its power from this premise. If it affirms your original signal you can go ahead full steam. If it does not, you can hold back and potentially defend yourself from a loss-making trade.
