Python

The low learning curve Python programming language has grown in popularity over the past decade. Data Scientists, algorithmic developers, quantitative financial professionals, and market enthusiasts have helped this become a strong tool for algorithmic research, development, and trading. Python for the trading industry comes with tools including:

  • Jupyter notebooks
  • NumPy for High-Speed Numerical Processing
  • Pandas for Efficient Data Analysis and Time Series Analysis Techniques
  • Matplotlib for Data Visualization
  • TA-Lib for Technical Analysis
  • Tensor flow

Why You Should Always Question The Status Quo — Tradeciety

,
CloudQuant was mentioned in this article by Tradeciety about trading psychology. We particularly like the comment saying “If you are so worried about algos, why don’t you look at Python? Read up on it. Cloudquant, Quantopian. The tools are there, the information is there, for free.” Change is progress, stagnation is death. That is the truest truth, especially in capitalism and thus also in trading. Grow or die. But then the real question is, why do so many people want to go backward? Everything was better before, we will make this and that great again, bla bla bla, yada yada yada. And why are so many people afraid of change when change is the only thing that ever brought humanity forward?
In Germany, we have this saying:”The farmer doesn’t eat what he doesn’t know”…that exactly describes the herd mentality. People are afraid of change because it involves an unknown factor. What will happen if we do that? What will happen if do this? I want to go back to my mommy. Where is my mommy? That is exactly what is happening in politics and in the world right now.

My First Algo on CloudQuant

, ,
Last week I mentioned my efforts to produce an algorithm on CloudQuant.com. As a reminder, they are a strategy incubator that provides historical data going back to 2011. If you can produce a trading or investment strategy that produces decent results they will license the algo from you and pay you a portion of the profits from that strategy. You don’t have to provide any capital; they provide it. This works for any python algo developer who are long on skills and short on capital. I used a well-documented strategy as defined in Jason Perl’s book “DeMark Indicators” (ISBN 978-1-57660-314-7 Bloomberg Press, New York 2008). The strategy is a Bearish TD Sequential Flip. This strategy is a basic technical strategy that utilizes bar data. CloudQuant lite, the default version, provides one minute bars. CloudQuant provides access to much more granular data on other versions of the data simply by requesting to be upgraded. For my purposes, and the purposes of this strategy the 1 minute bar data is perfect and fits easily for any python algo developer. The idea behind the strategy is to predict when a series of down bars indicate a time to buy. One hopes to buy low! The first component of the strategy is the “TD Bearish Price Flip.” The bear flip occurs when the close of a bar is greater than the close 4 bars earlier immediately followed by a close less than 4 bars earlier.

The second component is a countdown. The countdown gives a buy indication when an uninterrupted series of 9 closes occurs with each close being less than the close 4 bars earlier. Once we have the bear flip followed by a countdown of an uninterrupted series of 9 then I submit a buy at the market for that stock. This gets me into the position. To get out of the position I want to take profits or losses quickly. The strategy takes a profit at $0.15 per share and stops any losses at $0.30. If all this sounds complicated, it really isn’t. All told there are only about 60 lines of code written in Python. Python is easier to write than excel macros. There are more comment lines explaining what I was doing than lines of algo code. After back testing the strategy the results were mixed. Some losses, some winners. Nothing spectacular. The algo won’t likely get funded as written. The team at CloudQuant helped me out and placed the algo into their public scripts so that anyone can clone it and run the same tests. Better yet, you can use it as a foundation to start your own algo. Here are some ways that another python algo developer might want to consider to improve the strategy performance:
  1. Do a data study to optimize the target price for loss and profit taking.
  2. Do a data study to see if there is a max period of time that you should hold a position.
  3. Utilize other data other than just the close price in each bar
    1. Does the BarView open, high, low affect the success rate?
    2. Does the bidvol, or askvol affect the success rate?
    3. Does the vwap affect success rate?
    4. Does the spread between bid price and ask price change with success rates?
  4. Read the DeMark indicator book and apply more of the techniques past page 3 🙂
  5. Change the bar length to see if you can do this as a different time length
  6. Use a data driven approach to pick which stocks to run this algo upon
  7. Are there times of day approaches that would work better? Do the study.
  8. Does this strategy work for a market that is trending up or down better?
  9. Does this strategy work better for market capitalization size?
  10. This is implemented as a buy (long only) strategy. Implementing the sell short strategy could improve the returns.
