outdated libraries, broken functions, unused variables

[GGrosskreutz]

on the website which makes reference to this repo ('https://towardsdatascience.com/making-a-i-that-looks-into-trade-charts-62e7d51edcba')

function "convolve_sma" is called but not defined
mpl_finance cannot call candlestick2_ochl anymore, mplfinance.original_flavor.candlestick2_ochl seems to work
call time.time() but time isnt imported
realtime_data variable is called but never referenced

you could eliminate like 12 or more lines of code and make things a bit easier to understand with a similar file naming convention

broken tutorials are a huge source of frustration mostly on the new programmers.
every part of this tutorial has similar problems
surely the crypto affiliate is enough incentive to maintain your article/repo, no?
