MA Deviation
Overview This indicator displays the deviation rate between price and a moving average, and draws upper/lower bands using standard deviation.
Features
-
Deviation Rate Line – Displays how far the price has deviated from the moving average, expressed as a percentage.
- Formula: Deviation Rate = (Close / Moving Average × 100) − 100
-
Center Line – The moving average of the deviation rate.
-
Upper/Lower Bands – Statistical upper and lower boundaries calculated using standard deviation.
- Formula:
- Upper Band = Center Line + (Standard Deviation × Multiplier)
- Lower Band = Center Line − (Standard Deviation × Multiplier)
- Standard Deviation: double diff = RateBuffer[i - j] - CenterBuffer[i] / sum_sq_diff += diff * diff / StdBuffer[i] = MathSqrt(sum_sq_diff / period_for_calc)
- Formula:
Parameters
- (MAPeriod) – Moving average period used as the basis for the deviation rate (default: 20)
- (Center Line Period) – Moving average period for the deviation rate (default: 40)
- (StdDevMultiplier) – Standard deviation multiplier for determining the upper/lower bands (default: 2)
- (MAMethod) – Select from SMA, EMA, SMMA, or LWMA (default: SMA)
- (AppliedPrice) – Select from Close, Open, High, or Low (default: Close)
How to Read
- Deviation Rate Line (red) – Shows how far the price is from the moving average.
- Positive value: price is above the moving average
- Negative value: price is below the moving average
- Center Line (gray) – The average of the deviation rate (not the same as the zero line).
- Upper/Lower Bands (white dotted lines) – Statistically overbought/oversold zones.
- Deviation rate crossing above the upper band: potential overbought condition
- Deviation rate crossing below the lower band: potential oversold condition
Trading Strategies
-
Mean Reversion Strategy
- Sell signal: after the deviation rate exceeds the upper band and then turns downward
- Buy signal: after the deviation rate falls below the lower band and then turns upward
-
Trend Following Strategy
- During a strong uptrend, the deviation rate line may remain above the zero line.
- Buy signal: a golden cross between the center line and the deviation rate line while the center line is trading above the zero line
- Sell signal: a dead cross between the center line and the deviation rate line while the center line is trading below the zero line
