The Extreme Spike Indicator is, as the name suggests, a forex trading tool that recognizes spikes in the market. This is a perfect indicator for reversal traders. A spike often indicates a turn-around moment. The best way to use that gauge is to apply it to your favourite trading system as a filter. The indicator is displayed in a separate window placed just below the main trading chart. This indicator fits all kinds of timeframes and currency pairs. The default settings can be modified directly from the input tab. Feel free to experiment with the settings and parameters to fit your personal preferences..
