They also often do that through Native OS Events. Generally, file watchers offer functionality for the Creation, Amendment, Deletion, Existence and Rename of files. Unless a file-watcher is in place, someone would manually need to monitor for the arrival of the said file before manually kicking off the relevant daily process. Imagine for instance, that a daily process requires the arrival of a file from another department. The file-watcher, upon the arrival of any file, will trigger a follow-up process. A file-watcher is a process which monitors a specific directory for the arrival of any files.

I hope this algorithm will prove useful to you in the future.In this blog, we are going to build from scratch what is known as a ‘File Watcher’.

The GitHub Gist below contains all the code for the program.

Now you know how how to create the stock screener used by one of the best traders of all time!

Lastly, this code will print out a DataFrame of all the stocks that made the requirements and download the stocks to an excel file for your convenience. If a stock passes every one of the conditions, we can add it to our exportList of stocks that passed Minervini’s Trend Template! The rest of the code actually executes the screener with the principles that were mentioned earlier. The moving averages are used by calculating the rolling averages over the respective amount of days. The high and lows of the past year are taken by finding the maximum and minimum values in the DataFrame for the past 260 trading days (about a year). The current close price is used by taking the adjusted close price for the last day. From here, we can calculate the metrics we need to create the conditions. Instead of calculating the metrics for each one of the stocks, we can just include the top 30% of stocks that pass condition 8 of Minervini’s Trend Template (an RS value greater than 70). Finally, after the data manipulation with quantiles, we have a dataframe with the top 30% performing stocks in the given list as well as their respective RS values. The time.sleep(1) at the end of the for loop can also help curb potential errors with the influx of requests. To make the process faster, we can download the historical data for each stock over the past year instead of continually making requests to Yahoo Finance (which could cause errors). In this program, we have chosen a list of the ~500 stocks in the S&P 500 index so that is a large enough sample size. Since in this program the RS metric is calculated with a percentile value relative to other stocks in the given list, it is better to have a list of a greater amount of stocks to make the RS value more accurate. In Mark Minervini’s Trend Template, he looks for stocks with an RS value of 70 or higher (the top 30% performing stocks in the market). For example, if AAPL outperformed the market greater than MSFT in a specified time period, it would have a higher RS. Since the metric is exclusively used in IBD services, we can estimate the IBD RS by dividing the cumulative return of each stock over the cumulative return of the index and then create a percentile ranking for each stock out of 100. The IBD Relative Strength metric essentially calculates how a stock is performing relative to the market and other stocks during a specific time period. Now, we can calculate the cumulative return of the S&P 500 index over the past year and compare that value to the cumulative return for each stock in the S&P 500 during the same period.

If you do not have one of the following modules installed on your machine, use “pip install (module name)” in your terminal to download them. First, import the following dependencies. Now that you are familiar with the criteria, we can get into the code.

You can read more about this template in Mark Minervini’s blog post. The RS rating is a metric of a stock’s price performance over the last year compared to all other stocks and the overall market.
