TWS interactive brokers API with Python. Trouble putting live data together when received by several methods methods

Asked 2022-Feb-26 at 12:14

To give more context about my problem:

I am using python to build an API connecting to the TWS of interactive brokers. I managed to build something functional and able to fetch live data from contracts using the methods given in the doc of IB. Now that I want to use all the data to build other parallel systems with it, I have encounter problems organising the data that arrives from the IB server.

My program loops a list of 30 symbols to get live data from and then I want to put the data (ex. 'HIGH', 'LOW', 'CLOSE', 'VWAP' etc) from each symbol all together in one dataframe to calculate indicators and from there come up with an alert system that is based on them indicators.

This objective I have already accomplished it using only one symbol for the whole program. Is easy to store the data in instances or variables, pass it to a DataFrame and then calculate to set up alerts.

Now when looping a list of 30 values and receiving the data of all of them I have struggled trying to store the data for each symbol together and then calculate and set up alerts. Specially when I have to use several methods to receive the data (ex. I use tickPrice for some data and tickString for some other data) this several methods execute themselves one after the other but they wont necessarily have all the data at the same time, some values take more time than others to show.

I will show an example of my code to give even more context of my objective:

I need to search for a specific value followed, two cols. away, by specific value, without using col. names

The issue has been fixed in the upcoming Bixby Capsule SDK release targeted between 2/18 and 2/28.

In the meantime, there is a workaround explained in this article in the Bixby Developers Help Center that should get you unblocked. Please note all simulator settings will be reset as this workaround resets your local workspace.

If you continue to experience this issue after the release, please contact us via the "Contact Support" option in Bixby Developer Studio's "Help" dropdown menu.

Running 1000 functions gracefully using python multi-processing

Asked 2021-Feb-01 at 15:16

I'm trying to receive stock data for about 1000 stocks, to speed up the process I'm using multiprocessing, unfortunately due to the large amount of stock data I'm trying to receive python as a whole just crashes.

Is there a way to use multiprocessing without python crashing, I understand it would still take some time to do all of the 1000 stocks, but all I need is to do this process as fast as possible.

Ok, here is one way to obtain what you want in about 2min. Some tickers are bad, that's why it crashes.

Here's the code. I use joblib for threading or multiprocess since it doesn't work in my env. But, that's the spirit.

kivyMD APK crashes on start up (android)

I help me figure out what the problem may be.

Hi, I am having issues running my Kivy MD app on an android device. After compiling my app into an apk I use a USB stick to transfer the file onto an android phone. The app is successfully installed and loads up the kivy splash screen but then the app closes.

Install viv

You will also need to install deck.gl and other peerDependencies manually. This step prevent users from installing multiple versions of deck.gl in their projects. Breaking changes may happen on the minor version update. Please see the changelog for information.

Support

Viv's data loaders support OME-NGFF (Zarr), OME-TIFF, and Indexed OME-TIFF*. We recommend converting proprietrary file formats to open standard formats via the bioformats2raw + raw2ometiff pipeline. Non-pyramidal datasets are also supported provided the individual texture can be uploaded to the GPU (< 4096 x 4096 in pixel size). Please see the tutorial for more information. *We describe Indexed OME-TIFF in our paper as an optional enhancement to provide efficient random chunk access for OME-TIFF. Our approach substantially improves chunk load times for OME-TIFF datasets with large Z, C, or T dimensions that otherwise may incur long latencies due to seeking. More information on generating an IFD index (JSON) can be found in our tutorial or documentation.
