So for the first bar, the average was equal to the closing price of the first bar. For the second bar, the average was the (first + second bar close) / 2, and so on. After upgrading to version 0.7 the numbers are now what you would expect - NaN values until there are 20 bars to average. Thanks to Todd below for pointing this out.

Larry is the best teacher ever. Such amazing videos and value as always.

[@LongTu167]

This is amazing video. Thank you very much Larry!

[@investvest4571]

Awesome tutorial! Easy to follow. Thank you.

[@thedude3369]

Thank you for making these your videos are excellent and very informative.

[@nishadseeraj7034]

Just wanted to say Larry that I really appreciate your videos! I come from a stats and finance background so while I understand the finance concepts in theory and on paper with all of the nitty gritty maths , translating to code has never been easy for me. I have some experience but your videos are super and has made the transition so much smoother! Thanks mate and I'm looking forward for more stuff!

[@k2icc]

You make this look very easy, but I know you do know the stuff. Thanks a lot for taking the time to share it. That speeds up anyone learning experience by a lot.

[@typeer]

back again! great as always thanks larry

[@lorenzoquadrelli7237]

Exactly what I was looking for! Glad you decided to cover this library just now. Yesterday I was working on a bot hardcoding all the formula and math 😆 and than I found your video. It's gonna save me a lot of headaches 🤞🏽 cheers!

[@alibulus4382]

You are amazing dude.

[@cetilly]

Awesome topic and very well presented. I also prefer TA; good call

Great content! Can't wait for the next video! Would be very interesting if you back-test your upcoming supertrend strategy with backtrader

[@javidhb]

it was extremely useful.... tnx

[@kg6itc]

Be GREAT to see a video on Python Trading Bot using TA lib that alerts on price crossing MA, and MA's crossing.

[@tak68tak]

Awesome as usual. twelvedata is awesome btw. You can get a Pandas dataframe simply by from twelvedata import TDClient td = TDClient(apikey=twelve_key) ts = td.time_series('symbol'= 'AAPL') ts.as_pandas()

[@kg6itc]

Was there a part 2 for this? This is GREAT! Thanks!

[@IBetraye]

Hey Larry, first of all, great videos! You've helped me big time. How would you loop through a df where multiple coin pares are available, making it so that the ta trend functions are reapplied and recalculated on every pair in the df? Thanks!

[@maxxgray2539]

Looking forward on your next videos, are you going to use backtrader to test your strategies?

[@connorpatricks4922]

Hey Larry thanks a million for you videos man! Your lectures are so easy to follow and you explain even the most complex concepts to clearly yu make itso easy. Yu are a genius man. Im trying to transfer your supertrend code into freqtrade but its not working for me. I like freqtrade coz yu can give bot a select number of assets to trade on instead of running many bot instances. Or maybe is it possible to add more assets for bot to monitor in this supertrend strategy. Your ecample has eth/usdt just wondering if adding more would work. Thanks dude

[@MarcusVinicius-lq3fe]

Hi Larry I have watched all videos from API Binance Tutorial very nice! I have a question: which method returns me the market current/real time PERCENTAGE variation (from Ethereum for example) ? I got that just doing web scraping using selenium but I would like to get this info using the API.

[@in_the_6ix]

Hi Larry - awesome video - thanks so much! Curious behavior in the BollingerBands on my Windows PC (Python 3.8.4)... When I run "bars = exchange.fetch_ohlcv('ETH/USDT', limit=20)", I get NaN values for upper_band, lower_band, moving_average (except for the last row). If I remove the limit and use print(df[-20:]), the values are fine. Is anyone else seeing this output?

[@FranklinMinty]

Yes...Larry is a Wizard and can pull data from the past to calculate MA on the first bar. We're mere muggles...

[@IrfanA7861]

Yes I am having the same issue

[@IrfanA7861]

@@FranklinMinty Yes seriously how he got the 20 bars average?

[@parttimelarry]

Hey let me check on what the deal is here, you are right the result was strange but I didn't catch it while I was recording.

[@parttimelarry]

Great catch. It looks like the version I had on this machine is very early/old. I had ta version 0.5.11. The values you got are the behavior I would expect. On the old version, instead of filling the first X values with NaN, it averaged what it had so far. So the first value of the moving average was equal to the first close. The second value of the moving average was the (first close + second close) / 2 and so forth. I upgraded the package -- ran a pip3 install --upgrade ta and now I have ta version 0.7. I re-ran with newer data and the behavior is now what you have and what I would expect. I will make a note of this in the next video and in a pinned comment. Thanks for pointing this out.

[@ShujaathKhan]

How diff is this compared to finta or talib?

[@ayhanataman]

can we use for stock ?which library can i use

[@aryalsubsc]

I have local database table with Symbol, Date, Open, High, Low, Close, Volume columns. getOHLCfromDB(symbol, startdate, enddate) is the fuction which will extract OHLC data. I would like handler to work on extracted dataframe df. Is there possibilities to analysis for my local data.

[@adeisidaemon]

This library is a joy to use compared to ta-lib, it has a vortex indicator for a start, you don't have to dick about with dependencies on 64bit Windows, it is certainly more Pythonic like you say and it isn't as buggy. Cheers Larry.

[@ai.simplified..]

Is it possible to automate everything for online trading like a bot?

[@Invibcible]

You made 3 intresting stocks scanner videos in the past using TA-Lib, I could't install that library and I want to do a stocks scanner using the TA library in this video and I don't know how to start. Are you planning to remake the stocks scanner videos using TA?

Hello bor can u give example of SMA cross over using Pandas_ta plz

[@jackroark6928]

[@unyimeakn9615]

Can you do tutorial using redis thank you

[@tyler.farmer]

question on the Close Price: when you look at a bar with the OHLCV, is the Close value for that minute, or the previous minute? The reason I ask: The ATR calculations use the Max [ (High-Low), (Abs(High - Previous Close)), and (Abs(Low - Previous Close)). So wondering if we should use the Close value on the same row, or use the Close value from the Previous Row?

[@ThesniperScythe]

Did you figure this out?

[@lucksimi3320]

Hi Can get the code for WEEKLY supertrend? thanks

[@muratisler9954]

Thank you for the nice videos, I just wanted to say that, TA doesn't have MA types selection like TA-lib, different MA types are very important for trend trackers. Supertrend looks nice but not efficient and hard to optimize because it jumps on the bands :) For the first look, the super trend seems great but when you backtest it, the results are not good enough.

[@mikescarborough9196]

Supertrend is useful for visualizing trend reversals in terms of ATR magnitude, but it most definitely does not cut it as a standalone indicator. It’s not a bad filter though.

[@Mr.Jah99]

I have been using python38 and print (upper_band) it shows the powder as below. What did I do, where did I go wrong?

[@jamiekenber]

It's a pain to install TA-Lib but that's because it runs on faster native languages. Wouldn't want to be relying on Pandas to process thousands of stocks with any kind of frequency

[@xuan_learning]

I have one question that I hope someone can help me with. I think I have the identical code, but my upper_band= bb_indicator.bollinger_hband(); only return index 19 and the rest of the indexes are showing NaN. WHY?

[@giratinum]

increase the number of candles. BBand needs 20 candles to caculate but you give only 20 candles to it.

If only TradingView would come out with a Python version that replaces Pine Script.

I have a question :- i have written a strategy in Pine_script ( tradingview) but i want to convert it to python. Please can you tell which libraries can help me to do that because my strategy is very complex ? there are few limitation in pine script so i want to shift to python............Hope i get reply from you😎

[@jadhavpratik37]

Same problem with me. Since Pinescript is the language of TV, it might be a bit difficult to find a way around it

[@jack_sparrow1049]

@@jadhavpratik37 if u can understand the math of indicator or your custom formula/ indicator it is very easy to convert it to python using pandas if u don't have any custom indicator or formula then you can use " ta lib" library to make your algorithms as almost every indicator is available in that library 😀 Pine script is the best language for creating strategies if you stay with the pine script you will easily understand that

[@afblaze94]

What ide are you using in this video?

[@parttimelarry]
