Indicator Description

T3 (Triple Exponential Moving Average) is a trend indicator that reduces lag while maintaining sensitivity to trends through triple exponential smoothing.

Function Information

• Function Name: T3
• Input Parameters: #Kline
• Parameter Settings: timeperiod (default: 5), vfactor (default: 0.7)
• Output: T3 value

Calculation Principle

T3 is calculated using the following formulas:

a = vfactor
a2 = a * a
a3 = a2 * a
b = 1 - a
b2 = b * b
b3 = b2 * b
c1 = -a3
c2 = 3 * a2 + 3 * a3
c3 = -6 * a2 - 4 * a3
c4 = 1 + 3 * a + a3 + 3 * a2

T3 = c1 * e6 + c2 * e5 + c3 * e4 + c4 * e3

Where:

• e3, e4, e5, e6 are EMA values for different periods
• vfactor is the volume factor used to adjust the smoothing level

Usage Scenarios

1. Trend identification and tracking
2. Support and resistance level identification
3. Price breakout confirmation
4. Trading signal generation

Usage Recommendations

1. Adjust parameters based on market volatility
2. Use in combination with other technical indicators
