Stock-Alarm

An alarm for stock price. When the price of a stock is lower than or equal to certian threshold, you will get alert by email. In addition, when the price is higher than or equal to your expectation, an alarm email will be sent.

Warning: Do NOT distribute the script because the alert email is sent via a Gmail account, whose password is in the code.

Pre-Requisites

• Python 2.7+

Before Running

Set your stocks in stocks.csv by following the examples.

The headers in stocks.csv:

• ticker - stock symbol
• name - stock name for your convenience
• threshold - the low price triggering alarm
• expectation - the high price triggering alarm

Run

The code has been tested on Windows 8.1 and CentOS 7 (Linux).

$ python stock_alarm.py --email [email protected]

Set the email to receive the alarm. As running, you will see the prompt:

Company             Price     Alarm    Expect         Last Update
---------------------------------------------------------------------------
Apple              225.74    200.00    240.00     2018-09-29 18:58:05
Amazon            2003.00   1900.00   2200.00     2018-09-29 18:58:00
FaceBook           164.46    150.00    180.00     2018-09-29 18:58:05
Google            1207.08   1180.00   1250.00     2018-09-29 18:58:05
Nvidia             281.02    240.00    320.00     2018-09-29 18:58:05
Tesla              264.77    240.00    320.00     2018-09-29 18:58:00

The Price shows the latest stock price whose update time is denoted by Last Update. Alarm and Expect indicate the lower threshold and higher threshold for sending the alarm email.

Note: The setting of Alarm and Expect can be modified in stocks.csv (threshold and expectation) without interruption. However, adding and removing a stock requires restart.

TODO

• Potential bugs
• Fault checking, e.g., variable type
• Email checking
• Adding and removing stocks without interruption
• More stable stock server
• Unbalanced updating rate
