# Tillson T3 Moving Average

Created by Tim Tillson, the T3 indicator is a smooth moving average that reduces both lag and overshooting. [Discuss] ðŸ’¬

```
// C# usage syntax
IEnumerable<T3Result> results =
quotes.GetT3(lookbackPeriods, volumeFactor);
```

## Parameters

`lookbackPeriods`

* int* - Number of periods (

`N`

) for the EMA smoothing. Must be greater than 0 and is usually less than 63. Default is 5.`volumeFactor`

* double* - Size of the Volume Factor. Must be greater than 0 and is usually less than 2. Default is 0.7

### Historical quotes requirements

You must have at least `6Ã—(N-1)+100`

periods of `quotes`

to cover the warmup and convergence periods. Since this uses a smoothing technique, we recommend you use at least `6Ã—(N-1)+250`

data points prior to the intended usage date for better precision.

`quotes`

is a collection of generic `TQuote`

historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

## Response

```
IEnumerable<T3Result>
```

- This method returns a time series of all available indicator values for the
`quotes`

provided. - It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.

Convergence warning: The first`6Ã—(N-1)+250`

periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

### T3Result

`Date`

* DateTime* - Date from evaluated

`TQuote`

`T3`

* double* - T3 Moving Average

See Utilities and helpers for more information.

## Chaining

This indicator may be generated from any chain-enabled indicator or method.

```
// example
var results = quotes
.Use(CandlePart.HL2)
.GetT3(..);
```

Results can be further processed on `T3`

with additional chain-enabled indicators.

```
// example
var results = quotes
.GetT3(..)
.GetRsi(..);
```
