Can we rely on indicators?
There are many commercial indicators available in the Forex market including default (free). Never trade relying on indicators completely. Use the indicator to increase the perfection of the trade or order i.e. the indicator will help you to order according to the strategies you know and will act as a helping hand in your decision making. Whichever indicator you use, you must first understand its behavior, practice it well in the demo, understand the success rate of the indicator and then apply it in the live market. Since the indicator is an instrument based on technical analysis, the indicator can sometimes deviate from its normal direction due to fundamental news. So be careful. Learn and trade some common and good indicators.
