22:57 - IB Feedback: From my research, ib-insync is the way to go I believe. Unfortunately, IB requires you to use a Java applet to authenticate any API-based trading. Headless authentication isn't allowed so you have to have Trader Work Station or IB Gateway running in the background. The Gateway is the more lightweight option (memory-wise) since it exists simply to authenticate and faciliate API-based trading whereas TWS is a full desktop app with a GUI so people can click and trade. The second downside to IB is that the Gateway/TWS will intentionally log you off daily (I think it's daily, but possibly weekly). This is another so-called security mechanism. However, the upside to ib-insync is that it utilises IBC (IB Controller) which automates logging in to TWS/IBGW whenever you're logged out. Right now I'm looking at existing IBGW Docker images that sort this out. I've linked the two that look best to me below. All this is a bit of a pain but worth it for the low fees, high liquidity, international access, and access to a wide variety of markets. Resources: - ib-insync documentation: ib-insync.readthedocs.io/api.html - Check out 'Notebooks' and 'Recipes' for some good examples of how simple the code can be. - User group with lots of helpful info: groups.io/g/insync/ - IBC: github.com/IbcAlpha/IBC - This has superseded the old 'IBController'. - IBC is packaged with ib-insync. ib-insync docu on using IBC: ib-insync.readthedocs.io/api.html#ibc - IB Gateway Docker Containers - github.com/dvasdekis/ib-gateway-docker-gcp - github.com/manhinhang/ib-gateway-docker

Yay! PostgreSQL, also please show how to build a docker image. I was wondering, having one docker image that does all of the data collection and calculations and sending signals to another docker image that receives the signals, calculation results and only trades,. I have a small group of friends that will use the bot, each of their bots should store their own buy, sell, records, trade and do their own back testing. Is this something that can be done relatively easily?
@parttimelarry4 жыл бұрын
Definitely an actual Docker tutorial to come. As far as your thoughts on having multiple containers communicate, here are my thoughts. So instead of packaging all of these up into one big image, I would create a smaller docker image just for data collection/calculation in this case. So this container would just maintain a connection to a data feed, and would have the data analysis libraries (eg. pandas, indicator libraries, machine learning, whatever), and be slimmed down and customized to only know how to do the work it needs to do. Then a separate small image could just contain the libraries and logic for connecting to a broker and executing trades. To communicate, there would just be a message queue. In a previous job, we used Amazon SQS. So the data collection / calculation container you discuss would say "oh I have a signal, let me tell the trading container", then would send a message to SQS (or other system, you could even write the records to a database and make a simple queue that way). The other container that only knows how to execute trades would run a process that polls the queue for new signal messages. You could even run multiple processes and make sure they are up and running using supervisord if you are going to be publishing tons of messages and need a bunch of workers doing various things in parallel. So when the workers consume/receive the messages, they do their work, then go right back to checking the queue for any new signal messages that were received. You also might run PostgreSQL on its own and allow both containers to connect to it if both systems need to store data/results.

Hi PartTimeLarry. I'm new to the your channel (great by the way) and the elements within TradeKit are new to me but I'm here to learn and create a Trading Bot along with a dev platform. Quick question re TradeKit - what happened to this project, no updates in a while? Did you drop the project as it seems not to be up with your current thinking i.e. backtesting (you seem to favour VectorBT, Alpaca (I have to use IBKR because of broker restrictions for the country I live in, not checked Alpaca) ? I like your approach to TradeKit, common set of tools for you to teach against, get your followers up to speed quickly and a deployment to any local or cloud platform all container-ized.
@ievgeniikudko79692 жыл бұрын
Hi Larry. This is a pretty cool thing you put together. I have a general question on the architecture of this whole thing. Supposed I write an app that collects that data from a specific exchange via websocket. Then I would dockerize it, compose via yml and let it collect and store the data. Then another container will be working this data. Would this be a proper set up (i.e., splitting data collection and data usage in two separate containers)? My understanding is that if I don't split it in two containers, every time I change my "data usage" and re-build it, I will need to reset the entire database and all my previously collected data will be gone. Is that right? What is the best way to handle it?

At minute 44 you mention that it might be too much, perhaps you could have a "lean-with-larry" branch and a "just-the-basics" branch or something like that. I know from my perspective, we aren't all experienced enough to know what we might want or not want, so more is better. I can't thank you enough for building this and creating this video, it was a missing link for me that I've been wanting to learn and explore but wasn't prepared for the million different rabbit holes that I would have to go down, here you just gave us one giant rabbit hole. As a side note, I notice you don't use Anaconda, but I find that a lot of newer python folks, self-included, were taught to start with anaconda, and so have grown accustomed to working with conda environments, etc. If I wanted to keep with that tradition, would I just fork your repo, then somehow add anaconda or anaconda lite to this container? (wouldn't quite know how to do that, of course) but, If so, then could I stay up to date by setting your repo as the upstream and pulling in changes to my remote (my github fork), then down to my local instance (the container), while in the container (assuming git is installed in the container)? I assume rebuilding the container every time would be massively inefficient. BTW, I may have butchered the terminology there.

Kudos to you for the approach taken. I hate that I am just getting to this video because I have been going through the videos to build out the Trading Bot and thought I would comb through and see where all of this is going and ran into this video. My feedback is WOW. I think you are definitely on to something and I want to share what I think picks up where you left off when it comes to the Database Structure. I call it the "Header Washer". The idea is to bring in any CSV or xls file with different header names and have it update the Header Names to work with the code. There would be a Master Header Alias to make the updates automatically in the background. I have already written the code in VBA to work with Excel. It would not be too challenging to convert it to Python and I would be happy to share it with you if you think it has value to your vision. Thanks for your contribution. Example of my code is lets say 5 people had a Contacts Table. Each of them had a 1st name column and a Last Name column. The 1st name column you have in your code is First_Name. The 1st name column the 5 clients have are FName, F_Name, FirstName, FN, and first name. Likewise with the 2nd Name there are 5 different ways to express the last name. The Master Alias would look for all of these different alias of each column and update it ultimately to First_Name in the Table that is used in the code. This way our code is never broken by unmapped data no matter what order the column is in the table. What if First_Name in the import table is in index 5 and not index 0, the code would automatically identify this and place that column of data into the proper index. It's a huge time saver for working with clean table data that may still need a bit of cleaning up before this is done for Nulls etc. but you would have a strong head start on getting things up and running from someone who is fresh to the Docker Image and wanted to engage with the content with there content. Kudos again and let me know where you are with this. I am also curious about the effort that went into the Trading Bot series you finished in Oct/Nov, did you scrap it and do something else? Did you build upon it. I am trying to find where the end of this goes and what the results are. I am thinking that you should be feeding the homeless and passing our free dinners to people all over the World by now. That's what I plan on doing, Amen. P.S. Is having a guitar in the background a KZbin backdrop thing, or do you really play?, lol Just curious. P.S.2 Have you given Prox Mox a look? It appears to take the container concept to a whole new level in my opinion. But, I am not a Ninja like you are on what that could offer and would be interested in what you thought about it.

Thanks for the feedback here, agree with your points on locking the versions and possibly being a bit more selective and having different requirements.txt files for different "flavors". From the feedback I received so far, including all of the ML stuff slows things down quite a bit since those packages are huge. Including some lightweight indicator and backtesting libraries doesn't add much bloat though. Also could be good to just have a different config for each broker.

Do you (or anyone) know how (or if it's even possible) I could do something like the following decorator that I created to wrap asyncpg DB fetches with a connection from the pool and a transaction block? I'm working on a DB helper class and don't want to have to keep writing with statements for every function. I'd like to end up with an abstract function that accepts "sqlStatment" as an argument and then that function be decorated with the "@_connectionTransaction" that I've created to try and abstract away the pool/transaction and keep things DRY. Any help would be much appreciated

Thanks for your posts here, still need to catch up :). Will try out some of your techniques soon since I am trying out TimeScaleDB this week and your async code will come in handy.

@@parttimelarry No worries! Don't forget the class will need instantiating differently due to the async method that needs to happen at the initialisation stage. I've linked an example below. Also, you should consider shifting from requests to aiohttp, they work very similar but you won't get the blocking as with requests. # main.py # ----------------------------------- import yaml, aiohttp, asyncio, logging.config from database.AsyncDatabase import AsyncDatabase from client.AsyncHTTP import AsyncHTTP from database.StockData import StockData from config import APP_NAME, LOG_CONFIG_PATH from config import DB_HOST, DB_USERNAME, DB_PASSWORD, DB_PORT, DB_NAME async def main(): asyncDatabase, LOG = await _init() async with aiohttp.ClientSession() as clientSession: # Initialize asynchronous HTTP client and data classes asyncHTTP = AsyncHTTP(clientSession, LOG) stockData = StockData(asyncDatabase, asyncHTTP, 24, '1min', LOG) # Obtain all data we are interested in await stockData.populateStocks() # await stockData.populateHistoricalStockPriceData() await _destroy(asyncDatabase, LOG) async def _init(): # Parse the logging configuration file (run once here, application singleton) with open(LOG_CONFIG_PATH) as f: logConfig = yaml.load(f, Loader=yaml.FullLoader) # Load the parsed config logging.config.dictConfig(logConfig) LOG = logging.getLogger("app") LOG.info(f"{APP_NAME}: Application started") # Initialise asyncDatabase asyncDatabase = await _createAsyncDatabase(LOG) return asyncDatabase, LOG async def _createAsyncDatabase(LOG): asyncDatabase = AsyncDatabase(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_PORT, DB_NAME, LOG) # Asynchronous class function initialization await asyncDatabase._initAsync() return asyncDatabase async def _destroy(asyncDatabase, LOG): await asyncDatabase._destroy() LOG.info(f"{APP_NAME}: Application exited successfully") # Application entry point if __name__ == "__main__": asyncio.get_event_loop().run_until_complete(main()) # AsyncDatabase.py # ------------------------------------------ import asyncpg from pandas import DataFrame from config import DB_LOGGING_REF from .definitionsAndQueries import ( queryCreateStocksTable, queryCreateHistoricalStockPricesAndIndicatorsTable, queryStockSymbolsAndIds, dataFrameColumnsStockSymbolsAndIds, queryCreateTimeScaleDbExtentsion, queryConvertHistoricalToHyperTable, queryInsertStocks ) class AsyncDatabase: """Asynchronous TimescaleDB (PostgreSQL extension) class""" def __init__(self, DB_HOST, DB_USERNAME, DB_PASSWORD, DB_PORT, DB_NAME, LOG): self._host = DB_HOST self._username = DB_USERNAME self._password = DB_PASSWORD self._port = DB_PORT self._dbName = DB_NAME self.LOG = LOG self._connectionPool = None async def _initAsync(self): """Asynchronous function initializations for this class""" await self._createConnectionPool() await self._createAllTablesIfNotExist() async def _createConnectionPool(self): """Creates a pool of database connections for asynchronous usage""" if self._connectionPool is None: try: self._connectionPool = await asyncpg.create_pool( host=self._host, port=self._port, user=self._username, password=self._password, database=self._dbName, command_timeout=300 ) except Exception: self.LOG.exception("Failed in creating database connection pool") else: self.LOG.info(f"Successfully created database connection pool: {DB_LOGGING_REF}") async def _destroy(self): """Class destruction process""" if self._connectionPool is not None: await self._connectionPool.close() def _connectionTransaction(functionBeingWrapped): """Wraps function with pool connection and transaction block""" async def _connectionTransactionWrapper(self, *args): try: async with self._connectionPool.acquire() as _connection: async with _connection.transaction(): # Database interaction function that we wrap with a connection and transaction return await functionBeingWrapped(self, _connection, *args) except Exception: self.LOG.exception('Connection pool or transaction error: ') return _connectionTransactionWrapper async def _abstractExecute(self, _connection, SQL): """Executes an SQL command (or commands)""" try: await _connection.execute(SQL) except Exception: self.LOG.exception(f"{SQL} ") async def _abstractFetchAsDataFrame(self, _connection, SQL, dataFrameColumns): """Fetches values from database based on the SQL statement argument""" try: resultsRecords = await _connection.fetch(SQL) except Exception: self.LOG.exception(f"\"{SQL}\" ") else: # Convert results from records to dataframe return DataFrame(resultsRecords, columns=dataFrameColumns) @staticmethod def _SQLStringConcatenator(stringList): """Combines SQL multiple strings to form one execute statement with ';' statement terminators""" return ";
