# Tillson T3 Moving Average

get_t3(quotes, lookback_periods=5, volume_factor=0.7)

## Parameters

name | type | notes |
---|---|---|

`quotes` | Iterable[Quote] | Iterable of the Quote class or its sub-class. • See here for usage with pandas.DataFrame |

`lookback_periods` | int, default 5 | Number of periods (`N` ) for the EMA smoothing. Must be greater than 0 and is usually less than 63. |

`volume_factor` | float, default 0.7 | Size of the Volume Factor. Must be greater than 0 and is usually less than 2. |

### Historical quotes requirements

You must have at least `6×(N-1)+100`

periods of `quotes`

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

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

`quotes`

is an `Iterable[Quote]`

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

## Return

```
T3Results[T3Result]
```

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

provided. `T3Results`

is just a list of`T3Result`

.- It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.
- The first
`6×(N-1)`

periods will have`None`

values since there’s not enough data to calculate.

⚞

Convergence warning: The first`6×(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

name | type | notes |
---|---|---|

`date` | datetime | Date |

`t3` | float, Optional | T3 Moving Average |

### Utilities

See Utilities and Helpers for more information.

## Example

```
from stock_indicators import indicators
# This method is NOT a part of the library.
quotes = get_historical_quotes("SPY")
# Calculate 5-period T3
results = indicators.get_t3(quotes, 5, 0.7)
```
