I have just started to learn python.....Please don't stop...You are making remarkable videos.

[@tkd2703]

Dude. I learned more from this vid than from my 8 weeks in the intensive Python course. Specially because it is EXACTLY, 1000%, what I wanted to learn. Thank you, from the bottom of my heart. Liked, subbed, saved and everything else. Keep up the awesome work!

[@parttimelarry]

Glad you enjoyed the content, have a lot more in the works :)

[@darrenrich6657]

@@parttimelarry Hi buddy Any way I can just get this all from you. I get it you have more then like more up dated items and systems,.

[@mailsidney]

Hey Larry. These videos are gold for budding python programmers. Thanks and please keep them coming.

[@99445deva]

This is such an exceptional video made on financial programming using python. I cant thank you enough for this. Thanks a TON from bottom of my heart.

[@hamadacooking950]

Awesome....build a crypto scanner using python.....you are a good teacher.

[@FranckePeixoto]

very cool dude! To simplify the beginning of the video: patternRecognition ={} for cdl in dir(talib): if cdl.startswith('CDL'): description = getattr(talib,cdl).__doc__ description = description.splitlines()[2] description = description[:description.find('(')].strip() patternRecognition[cdl] = description print(patternRecognition)

[@flam_g1]

I already commented positively 2 months ago but now I implemented following your guidelines and I can now customize it as I like. Great work ! Congrats !

[@yingkitchow5160]

this is 10/10. Thank you so much for sharing this! just found you couple days ago and im sure ill be learning a lot more from you this Christmas.

[@dtsu3732]

im a complete noob but these videos help me to create some kind of logic, Thanks bro!!!im trying to recreate the steps and it all makes more sense now

[@johbontha1550]

Damn this scanner is a thing of beauty. Been watching a few from last week. INTC was engulfing pattern in your scan and it popped today. Truly not deserving of this free resource!!! Stumbled on gold here struggling with pyfi libs. You're the hero WSB needed.

[@lukash7660]

for anyone who is having issues when trying to copy image address of the chart, just type in manually url from the video, it still works

[@justtohost3431]

Incredible! That's insane!

[@SolidBuildersInc]

OK, When I saw how "Eloquently" you just turned a list of "Patterns" into a Dictionary and kept getting the code done with a Loop, lol , I KNOW you have been around the Block a few times. I just learned the coolest Hack for comprehensive coding with Loops, Thanks

[@ihebbibani7122]

Once again , excellent content !

[@RicardoDacostaRaghavendra]

Simply amazing! Thank you for sharing this knowledge with us!!!

[@tugrulhan]

Another very helpful video. Much appreciated. It was my first experience with the Flask module, but your explanation and walkthrough were really simple and clear to follow. I learned so much from this video. Looking forward to the next one

[@parttimelarry]

Thanks, will add on to this series this weekend.

[@sydneywayman4230]

this was amazing. thank you for showing how to do this.

[@1980steph]

Hi Larry, thank you for the great video's. Learning so much. I used to program in pine script only. But now thanks to you, I am learning python, it is so much fun and well explained.

Thanks Larry, really enjoyed following this!

[@parttimelarry]

Thanks for watching, going to do some add-ons to this.

[@Magmatic91]

Best tuto. Thank you so much.

[@vatsid]

Great job!! I have found most TA and candlestick patterns work best when institutional supply demand forces are in play. That means the timeframe should be weekly or monthly. Easy to change code to weekly for instance ? Happy to DM and compare notes :)

[@SolidBuildersInc]

Now that's interesting. We were just about to code this up with 1 minute candle sticks. Do you have some back-testing or test in general that compares the win rate of the different Timeframes. This is the first of me hearing about this "1 week" sitting as "Timeframe of choice". Thanks for sharing

[@PavelSumik]

unbelievable, fantastic

[@Asparuh.Emilov]

Thank you so much for the great content!

[@Chadward_]

Really good stuff, adapted this to crypto's from yahoo finance but working on adding support for other crypto market data!

[@typeer]

thanks for this! v much appreciated thought i'd comment this out in case anyone else runs into it: for TSX stocks up in north here, the tickers read as EXA.TO, so symbol = filename.split('.')[0] returns a key error my workaround was symbol = filename rsplit('.', 1)[0] i think this works as a globally applicable syntax for non-NYSE exchanges with dots in the tickers

[@mitchaspinall6658]

Thanks for that, worked well for me. Did you manage to get the charts to work on the web app?

[@ItsGlexyWolff]

I want to make this but for DOGE coin, where should I make the changes?

Thank you so much! This is amazing!

[@bhaveshvarshney222]

this is simply brilliant

[@bhattvd1]

Hello Larry, I thoroughly enjoyed your video. You are so good at this. You should change your name to "Full Time Larry"! One Question: The "last" values returned by pattern recognition function are typically 0, 100 or -100. When we see 200 or -200 they are with 'confirmation'. I could not find any such pattern. Do we need to change .tail or something else in the code to accomplish this? I hope I am making my question clear to you.

[@simonhong7772]

Hi Larry, your fans here. I have followed and Github your resource code and playing it with no issue (except an error on app.py(line49) where the "Except" function keeps occurred an error but could ignore. However, if I converted to my country symbol.csv (all the format same and was successfully download and loaded) it keeps output failed on filename: my list where I have tried all the pattern scans.I really lost and dont know what to do as this is a superb tutorial. Many thank for your advice. Cheers,

[@rverm1000]

nice! you make learning python so easy. that is a nice app to. it would be nice if i could use that in real time on one minute candles

[@dy6752]

You can do this but youre going to be dealing with A LOT of data. You would need to use a database instead of csv files.

[@chubagarfieldmoganedi9681]

Dope shit!

[@biswajitsardar4260]

Hi Larry, I am too exited, It was quite useful the Candlestick Screener for US market, it works. But 1) for the Indian Market, NSE, BSE exchanges, is there a source of "O,H,L,C" data in the same way can be interfaced as I have not much idea on the coding. 2) If you can make a extra button for "Download Data" and necessary linking. I could create a button, but could not link to make it functional. If you have some time to look at these. Thanks.

[@Chaitukr85]

Even I tried to check via yfinance and it didnt recognise the indian scrips. One way would be to download the eod data from yfinance itself as an excel sheet and then use it to load your data . Also there are other sites like Bhavcopy , or some sites which has historical data. Actually, even NSE has the historical data, but it will take some time to clean it up to the format that you need.

[@westnash]

PLEASE make your fonts larger as the coding is no use if you move fast and with tiny lines. Or show the finished code in an adjoining text.

[@westnash]

OK I see the link but havent looked at it yet.....thanks.

[@LatinoWebStudio]

Do you have videos on creating your own trading bots? Do you know if a trading bot can be used on a paper trading account? This question is based on the idea of what's the best way to use Python to become a better trader.

[@SolidBuildersInc]

Hey Larry, I was wanting to replicate this same ability using Streamlit instead of Flask. Do you think Streamlit can pull this off rather easily? I would like to see how you would approach this. Flask seems to have some built features that Streamlit does not have and it is making it a bit of a challenge. For ex. Is "import request" available for Streamlit ? Scratching my head...........Thanks for any examples to get me started....

[@Rapid1898]

At 50:34 you are copying the image-url from the chart In my chrome-browser on windows i do not have this option on right click. Is this only a feature which exists in MacOS?

[@nishadseeraj7034]

Such an awesome channel Larry! I just started my first investment analyst job and your stuff is so invaluable. Question: Do you think its possible to make the same app using streamlit?

[@jaderson-dsnaveia]

Larry is behind of 93% of population.

[@jaderson-dsnaveia]

Yes It is. I already does a functional dashboard with Stream lit and live data, with and without training providing by third part. I'm raising a busi ness, with algo trading background. If you need something, I could help: jadersonBK Regards.

[@sandipancoding7978]

Thanks you sir.. The video is really great and very accurate but sir can you also customise it a bit so it also gives alert with the web app whenever a pattern is taking place in the live market.. i.e if a specific pattern is occurring in the live market the app alerts us about it? And if it can be done can you please make a video on that as a follow up to this.. Thank you❤️

[@Seankim-vj1fl]

Using TALIB for pattern recognition 30:00

[@TheL337trance]

What's the title of the video that shows how to get the data for the s&p 500?

[@GodX36999]

I would like to buy you a coffee by paypal so how can I do

[@scorpioM56]

How do you build a fundamental screener with live data as the market opens? Criteria such as, percentage, float and volume etc.

[@ClockDesignCo]

great work mam. really impressive

[@arthurdavis762]

I’m so glad I found you. I’m very fascinated with automated trading and I use a MAC system like you. Would you recommend learning Swift or Python?

[@brianobush]

Swift is for iOS devices; Python is so much more useful IMO. The machine learning libraries alone make Python a winner.

[@parttimelarry]

Agreed, would focus on Python unless you are only focusing on native iOS/Mac apps. Python has the easiest to use libraries for finance and data analysis. Even if you are making an iPhone app, I would write the backend API's in Python.

[@yunxingliu8177]

how do you deploy it on a could like aws and let it runs forever in the background. Once it detects a desired pattern it sends out a notification.

[@yaboiiprettyeyez]

hey Larry, what video did you make candlestick charts in?? I wanna learn how to make them from scratch =)

[@Helsiza]

This is oustanding. However, I wanted the candlestick screener to show currencies against currencies (eg; USD/EUR), and I also want it to show the current market trend and to determine candlestick patterns for about three or four candlesticks. How do I do that?

[@user-me3wp5ve1y]

Great Video.I tried to download the CSV files for NSE FNO list.But doesn't pull down any data.NSE symbols ends with .NS,so replaced the same in symbols list.Any help?

[@mjjabarian8246]

Can you recommend a way to write historical stock data in Postgres or any other db instead of saving as CSV?

[@prabhu_patil]

Wonderful larry

[@rohitchadha3916]

Quite Awesome ! Just one query, for any non S&P Stock when scan is run it says "failed on filename: NonSPCompany.csv", can you please advice what would be the issue, symbol list etc. all are updated. Thank you once again!
