I am very new to both python and the Quantopian API, and I was hoping to find some help with how I should start visualizing data for research.
I have three things I want to do:
- Plot the price of an asset every 30 minutes for the period of a week
- Plot an SMA20 of this data
- Plot the RSI20 of this data, either on a separate graph or on the same graph with a scaled axis
I want to do these things just to learn how to visualize before I get into deeper and actual research. I understand that the first 'Getting Started' lesson showed how to plot the closing price and SMA, but I want these plotted based on smaller periods of time.
Seeking Help with Data Visualization
Furthermore, I would like to know if anybody knows how to also automate/optimize their asset research because I feel as if manually searching through symbols and then determining whether they're worth researching or screening is very tedious and time consuming. I was wondering if it was possible to build a scraper for a site like finviz that automates some of the manual portions of their screener.
Take a look at the research tutorials to learn about accessing the data and plotting: https://www.quantopian.com/research/Tutorials%20and%20Documentation
You can also search the community forums for examples that people have shared. Here is notebook tinkering with SMA: https://www.quantopian.com/posts/basic-stuff-conventions-slash-sma-slash-ema-slash-pandas-slash-np-arrays-slash-talib
There are ways to automate and optimize your research, depending on what you're trying to extract. The forums are generally a good source to search through methods people have shared. Once you have something interesting, run it through Alphalens that will show you the predictive power of your factor. Here's a lecture that steps through it.
