Forex Indicator - Price Envelopes

Price envelopes consist of 2 moving averages and are plotted at a set percentage above and below a 3rd moving average. Price envelopes can be used to indicate overbought and oversold levels. Overbought conditions are found at the upper band and oversold conditions at the lower band.

Price envelopes consist of three moving averages:
• a middle band being a N-period simple moving average or exponential moving average (SMA or EMA)
• an upper moving average (SMA or EMA - upper band) plotted at a set percentage above the middle band
• a lower moving average (SMA or EMA -lower band) plotted at a set percentage below the middle band
The Percentage should be set so that about 85% of currency price activity is contained within the upper and lower bands. If currency price volatility increases/decreases, than adjust the bands %.

Interpretation

The interpretation is similar to Bollinger band Price Envelopes define the upper and lower boundaries of a currency pair's (or other instrument) normal trading range.

Popular Trading Signals from Price Envelopes

I. In trending markets
