Key_Reversal Indicator For MT5

Key_Reversal Indicator For MT5

The Key_Reversal Indicator For MT5 displays the key reversal zone with the help of three bars or engulfing patterns. The engulfing pattern is a strong reversal signal that is used by the elite investors.

The indicators have five unique input levels. The trend detection period is used to deal with the number of bars that will be assessed to find the trend direction. The filter adjust segment is for the advanced traders who love to trade the cross pairs in the market. The signals are generated in the form of a red and blue arrow. Red arrow indicators a new down trend is going to take place. On the contrary, the blue arrow indicates a new up trend is going to dominate the market. This indicator is equipped with an advanced alert system that can generate email alerts. If you are super busy, you can use the SMS alert system of this indicator.

However, jumping into the trades with the arrow marking is a big mistake. Analyze the condition of the market and determine the lot size accordingly.
