Programming Conventions

Pandas TA has three primary "styles" of processing Technical Indicators for your use case and/or requirements. They are: Standard, DataFrame Extension, and the Pandas TA Strategy. Each with increasing levels of abstraction for ease of use. As you become more familiar with Pandas TA, the simplicity and speed of using a Pandas TA Strategy may become more apparent. Furthermore, you can create your own indicators through Chaining or Composition. Lastly, each indicator either returns a Series or a DataFrame in Uppercase Underscore format regardless of style.


Standard

You explicitly define the input columns and take care of the output.

  • sma10 = ta.sma(df["Close"], length=10)
    • Returns a Series with name:
      SMA_10
  • donchiandf = ta.donchian(df["HIGH"], df["low"], lower_length=10, upper_length=15)
    • Returns a DataFrame named
      DC_10_15
      and column names:
      DCL_10_15, DCM_10_15, DCU_10_15
  • ema10_ohlc4 = ta.ema(ta.ohlc4(df["Open"], df["High"], df["Low"], df["Close"]), length=10)
    • Chaining indicators is possible but you have to be explicit.
    • Since it returns a Series named
      EMA_10
      . If needed, you may need to uniquely name it.


Pandas TA DataFrame Extension

Calling

df.ta
will automatically lowercase OHLCVA to ohlcva: open, high, low, close, volume, adjclose. By default,
df.ta
will use the _ohlcva
for the indicator arguments removing the need to specify input columns directly. *
sma10 = df.ta.sma(length=10)
* Returns a Series with name:
SMA_10
*
ema10_ohlc4 = df.ta.ema(close=df.ta.ohlc4(), length=10, suffix="OHLC4")
* Returns a Series with name:
EMA_10_OHLC4
* Chaining Indicators require specifying the input like:
close=df.ta.ohlc4()
. *
donchiandf = df.ta.donchian(lower_length=10, upper_length=15)
* Returns a DataFrame named
DC_10_15
and column names:
DCL_10_15, DCM_10_15, DCU_10_15

Same as the last three examples, but appending the results directly to the DataFrame

df
. *
df.ta.sma(length=10, append=True)
* Appends to
df
column name:
SMA_10
. *
df.ta.ema(close=df.ta.ohlc4(append=True), length=10, suffix="OHLC4", append=True)
* Chaining Indicators require specifying the input like:
close=df.ta.ohlc4()
. *
df.ta.donchian(lower_length=10, upper_length=15, append=True)
* Appends to
df
with column names:
DCL_10_15, DCM_10_15, DCU_10_15
.


Pandas TA Strategy

A Pandas TA Strategy is a named group of indicators to be run by the strategy method. All Strategies use mulitprocessing except when using the

col_names
parameter (see below). There are different types of Strategies listed in the following section.


Here are the previous Styles implemented using a Strategy Class:

# (1) Create the Strategy
MyStrategy = ta.Strategy(
    name="DCSMA10",
    ta=[
        {"kind": "ohlc4"},
        {"kind": "sma", "length": 10},
        {"kind": "donchian", "lower_length": 10, "upper_length": 15},
        {"kind": "ema", "close": "OHLC4", "length": 10, "suffix": "OHLC4"},
    ]
)

(2) Run the Strategy

df.ta.strategy(MyStrategy, **kwargs)



Pandas TA Strategies

The Strategy Class is a simple way to name and group your favorite TA Indicators by using a Data Class. Pandas TA comes with two prebuilt basic Strategies to help you get started: AllStrategy and CommonStrategy. A Strategy can be as simple as the CommonStrategy or as complex as needed using Composition/Chaining.

  • When using the strategy method, all indicators will be automatically appended to the DataFrame
    df
    .
  • You are using a Chained Strategy when you have the output of one indicator as input into one or more indicators in the same Strategy.
  • Note: Use the 'prefix' and/or 'suffix' keywords to distinguish the composed indicator from it's default Series.

See the Pandas TA Strategy Examples Notebook for examples including Indicator Composition/Chaining.

Strategy Requirements

  • name: Some short memorable string. Note: Case-insensitive "All" is reserved.
  • ta: A list of dicts containing keyword arguments to identify the indicator and the indicator's arguments
  • Note: A Strategy will fail when consumed by Pandas TA if there is no
    {"kind": "indicator name"}
    attribute. Remember to check your spelling.

Optional Parameters

  • description: A more detailed description of what the Strategy tries to capture. Default: None
  • created: At datetime string of when it was created. Default: Automatically generated.


Types of Strategies

Builtin

# Running the Builtin CommonStrategy as mentioned above
df.ta.strategy(ta.CommonStrategy)

The Default Strategy is the ta.AllStrategy. The following are equivalent:

df.ta.strategy() df.ta.strategy("All") df.ta.strategy(ta.AllStrategy)

Categorical

# List of indicator categories
df.ta.categories

Running a Categorical Strategy only requires the Category name

df.ta.strategy("Momentum") # Default values for all Momentum indicators df.ta.strategy("overlap", length=42) # Override all Overlap 'length' attributes

Custom

# Create your own Custom Strategy
CustomStrategy = ta.Strategy(
    name="Momo and Volatility",
    description="SMA 50,200, BBANDS, RSI, MACD and Volume SMA 20",
    ta=[
        {"kind": "sma", "length": 50},
        {"kind": "sma", "length": 200},
        {"kind": "bbands", "length": 20},
        {"kind": "rsi"},
        {"kind": "macd", "fast": 8, "slow": 21},
        {"kind": "sma", "close": "volume", "length": 20, "prefix": "VOLUME"},
    ]
)
# To run your "Custom Strategy"
df.ta.strategy(CustomStrategy)


Multiprocessing

The Pandas TA strategy method utilizes multiprocessing for bulk indicator processing of all Strategy types with ONE EXCEPTION! When using the

col_names
parameter to rename resultant column(s), the indicators in
ta
array will be ran in order.
# VWAP requires the DataFrame index to be a DatetimeIndex.
# * Replace "datetime" with the appropriate column from your DataFrame
df.set_index(pd.DatetimeIndex(df["datetime"]), inplace=True)

Runs and appends all indicators to the current DataFrame by default

The resultant DataFrame will be large.

df.ta.strategy()

Or the string "all"

df.ta.strategy("all")

Or the ta.AllStrategy

df.ta.strategy(ta.AllStrategy)

Use verbose if you want to make sure it is running.

df.ta.strategy(verbose=True)

Use timed if you want to see how long it takes to run.

df.ta.strategy(timed=True)

Choose the number of cores to use. Default is all available cores.

For no multiprocessing, set this value to 0.

df.ta.cores = 4

Maybe you do not want certain indicators.

Just exclude (a list of) them.

df.ta.strategy(exclude=["bop", "mom", "percent_return", "wcp", "pvi"], verbose=True)

Perhaps you want to use different values for indicators.

This will run ALL indicators that have fast or slow as parameters.

Check your results and exclude as necessary.

df.ta.strategy(fast=10, slow=50, verbose=True)

Sanity check. Make sure all the columns are there

df.columns


Custom Strategy without Multiprocessing

Remember These will not be utilizing multiprocessing ```python NonMPStrategy = ta.Strategy( name="EMAs, BBs, and MACD", description="Non Multiprocessing Strategy by rename Columns", ta=[ {"kind": "ema", "length": 8}, {"kind": "ema", "length": 21}, {"kind": "bbands", "length": 20, "colnames": ("BBL", "BBM", "BBU")}, {"kind": "macd", "fast": 8, "slow": 21, "colnames": ("MACD", "MACDH", "MACDS")} ] )

Run it

df.ta.strategy(NonMPStrategy) ```



DataFrame Properties

adjusted

# Set ta to default to an adjusted column, 'adj_close', overriding default 'close'.

Performance Metrics   BETA

Performance Metrics are a new addition to the package and consequentially are likely unreliable. Use at your own risk. These metrics return a float and are not part of the DataFrame Extension. They are called the Standard way. For Example:

import pandas_ta as ta
result = ta.cagr(df.close)

Available Metrics

  • Compounded Annual Growth Rate: cagr
  • Calmar Ratio: calmar_ratio
  • Downside Deviation: downside_deviation
  • Jensen's Alpha: jensens_alpha
  • Log Max Drawdown: logmaxdrawdown

  • Sharpe Ratio: sharpe_ratio
  • Sortino Ratio: sortino_ratio
  • Volatility: volatility



Changes

General

  • A Strategy Class to help name and group your favorite indicators.
  • Some indicators have had their
    mamode
    kwarg updated with more moving average choices with the Moving Average Utility function
    ta.ma()
    . For simplicity, all choices are single source moving averages. This is primarily an internal utility used by indicators that have a
    mamode
    kwarg. This includes indicators: accbands, amat, aobv, atr, bbands, bias, efi, hilo, kc, natr, qqe, rvi, and thermo; the default
    mamode
    parameters have not changed. However,
    ta.ma()
    can be used by the user as well if needed. For more information:
    help(ta.ma)
    • Moving Average Choices: dema, ema, fwma, hma, linreg, midpoint, pwma, rma, sinwma, sma, swma, t3, tema, trima, vidya, wma, zlma.
  • An experimental and independent Watchlist Class located in the Examples Directory that can be used in conjunction with the new Strategy Class.
  • Linear Regression (linear_regression) is a new utility method for Simple Linear Regression using Numpy or Scikit Learn's implementation.
  • Added utility/convience function,
    to_utc
    , to convert the DataFrame index to UTC. See:
    help(ta.to_utc)
    Now as a Pandas TA DataFrame Property to easily convert the DataFrame index to UTC.


Breaking Indicators

  • Trend Return (trend_return) when given a trend Series like
    close > sma(close, 50)
    it now returns by default log and cumulative log returns of the trend as well as the Trends, Trades, Trade Entries and Trade Exits of that trend. Now compatible with vectorbt by setting
    asbool=True
    to get boolean Trade Entries and Exits. See:
    help(ta.trend_return)

New Indicators

  • Arnaud Legoux Moving Average (alma) uses the curve of the Normal (Gauss) distribution to allow regulating the smoothness and high sensitivity of the indicator. See:
    help(ta.alma)
    trading account, or fund. See:
    help(ta.drawdown)
  • Even Better Sinewave (ebsw) measures market cycles and uses a low pass filter to remove noise. See:
    help(ta.ebsw)
  • Tom DeMark's Sequential (td_seq) attempts to identify a price point where an uptrend or a downtrend exhausts itself and reverses. Currently exlcuded from
    df.ta.strategy()
    for performance reasons. See:
    help(ta.td_seq)

Updated Indicators

  • ADX (adx): Added
    mamode
    with default "RMA" and with the same
    mamode
    options as TradingView. See
    help(ta.adx)
    .
  • Average True Range (atr): The default
    mamode
    is now "RMA" and with the same
    mamode
    options as TradingView. See
    help(ta.atr)
    .
  • Bollinger Bands (bbands): New argument
    ddoff
    to control the Degrees of Freedom. Default is 0. See
    help(ta.bbands)
    .
  • Chande Kroll Stop (cksp): Added
    tvmode
    with default
    True
    . When
    tvmode=False
    , cksp implements “The New Technical Trader” with default values. See
    help(ta.cksp)
    .
  • Decreasing (decreasing): New argument
    strict
    checks if the series is continuously decreasing over period
    length
    . Default:
    False
    . See
    help(ta.decreasing)
    .
  • Increasing (increasing): New argument
    strict
    checks if the series is continuously increasing over period
    length
    . Default:
    False
    . See
    help(ta.increasing)
    .
