Pivot points are used to notice importance levels during a trading session. I have used them successfully for day trading as they are solid inflection points.
Read more here - https://tradingsim.com/blog/pivot-points/
Pivot Point (PP) = (Prior Daily High + Low + Close) / 3
R1 = (2 x Pivot Point) – Prior Daily Low
R2 = Pivot Point + (Prior Daily High – Prior Daily Low)
S1 = (2

The Series.map() function should enable the usage of index in the passed lambda, just like the normal Array.map() function does. My example use case is calculating a moving average, which requires referencing values next to the current position in the Series.

We would like to compute a power function (like 2**4 = 2 * 2 * 2 * 2) in datafusion
@matthewmturner asks for it here: apache/arrow-datafusion#147 (comment)
Describe the solution you'd like
Implement the power function as described in
Example:
In the image below the word starships should begin on a new line to avoid being split.
Terminal width is provided to determine how many columns to print. The terminal width or the total width of the column headers may be used to wrap the text in the footer.

Hi ,
I am using some basic functions from pyjanitor such as - clean_names() , collapse_levels() in one of my code which I want to productionise.
And there are limitations on the size of the production code base.
Currently ,if I just look at the requirements.txt for just "pyjanitor" , its huge .
I don't think I require all the dependencies in my code.
How can I remove the unnecessary ones ?

For pipeline stages provided by the pdpipe.basic_stages, supplying conditions to the prec and post keyword arguments may not return the correct error messages.
Example Code
import pandas as pd; import pdpipe as pdp;
df = pd.DataFrame([[1,4],[4,5],[1,11]], [1,2,3], ['a','b'])
pline = pdp.PdPipeline([
pdp.FreqDrop(2, 'a', prec=pdp.cond.HasAllColumns(['x']))
])
