Plotting TA-Lib indicators¶

TA-Lib indicators are compatible with both pandas nad polars backends.

In [2]:

from mplchart.chart import Chart
from mplchart.samples import sample_prices
from mplchart.primitives import Candlesticks, OHLC, Volume, LinePlot, Pane

from talib.abstract import Function

prices = sample_prices(backend="polars")

from mplchart.chart import Chart from mplchart.samples import sample_prices from mplchart.primitives import Candlesticks, OHLC, Volume, LinePlot, Pane from talib.abstract import Function prices = sample_prices(backend="polars")

Candlesticks with SMA, RSI and MACD¶

In [3]:

title = "Candlesticks with SMA, RSI, and MACD"

Chart(prices, title=title, max_bars=250).plot(
    Candlesticks(),
    Function("SMA", 50),
    Function("SMA", 200),
    Pane("above"),
    Function("RSI"),
    Pane("below"),
    Function("MACD")
).show()

title = "Candlesticks with SMA, RSI, and MACD" Chart(prices, title=title, max_bars=250).plot( Candlesticks(), Function("SMA", 50), Function("SMA", 200), Pane("above"), Function("RSI"), Pane("below"), Function("MACD") ).show()

Bollinger Bands¶

In [4]:

title = "Bollinger Bands"

Chart(prices, title=title, max_bars=150).plot(
    Candlesticks(),
    Function("BBANDS", 20),
).show()

title = "Bollinger Bands" Chart(prices, title=title, max_bars=150).plot( Candlesticks(), Function("BBANDS", 20), ).show()

Stochastic Oscillator¶

In [5]:

title = "Stochastic Oscillator"

Chart(prices, title=title, max_bars=250).plot(
    Candlesticks(),
    Pane("below"),
    Function("STOCH")
).show()

title = "Stochastic Oscillator" Chart(prices, title=title, max_bars=250).plot( Candlesticks(), Pane("below"), Function("STOCH") ).show()

Parabolic Stop and Reverse¶

In [6]:

title = "Parabolic Stop and Reverse"

Chart(prices, title=title, max_bars=150).plot(
    Candlesticks(),
    Function("SAR") @ LinePlot(style="marker"),
).show()

title = "Parabolic Stop and Reverse" Chart(prices, title=title, max_bars=150).plot( Candlesticks(), Function("SAR") @ LinePlot(style="marker"), ).show()

Hilbert Transform¶

In [7]:

title = "Hilbert Transform"

Chart(prices, title=title, max_bars=150).plot(
    Candlesticks(),
    Pane("below"),
    Function("HT_SINE"),
    Pane("below"),
    Function("HT_DCPHASE"),
    Pane("below"),
    Function("HT_DCPERIOD")
).show()

title = "Hilbert Transform" Chart(prices, title=title, max_bars=150).plot( Candlesticks(), Pane("below"), Function("HT_SINE"), Pane("below"), Function("HT_DCPHASE"), Pane("below"), Function("HT_DCPERIOD") ).show()
