This script will automatically buy and sell stocks for you.
 

 
You need all Stock Market upgrades (WSE Account, TIX API Access, Market Data TIX API Access, 4S Market Data Access, $31.2b total cost) and 19.7 Gb RAM to run this script.
 
 
This is modification of the original script from another steam guide
 
https://steamcommunity.com/sharedfiles/filedetails/?id=2708673262&searchtext=stock – [steamcommunity.com]  , I’m not the primary creator
 
 
This modification has more potential in various situations, especially during growth phase: I got the “wolf of wall street” achievement (make 1q on the stock market) by running mod. script overnight.
 
 

Code

Terminal: nano stockbot.js
 
Remove all the default file contents (blank file)
 
Copy-paste the below code in and save
 
Terminal: run stockbot.js
 
 
To quick launch this script after augmentation, use alias:
 
Terminal: alias restart=”run stockbot.js”
 
After, you able to type in terminal box restart to quick launch without necessity of type full command (you also able to add necessary commands to this alias through ; and they all would be executed).

Changelog

Ver. 1.0- comparison with the original script from https://steamcommunity.com/sharedfiles/filedetails/?id=2708673262&searchtext=stock – [steamcommunity.com] 
 

• Removed some player-changeable variables due to trading strategy revision (will be listed below)
• Changed some player-changeable variables values. Now all player money considered available basically: to make money you should spend money (changeable)
• Added MIN_SPEND variable to prevent loss from commissions more than potential profit
• Removed some obvious logs like cycle counter
• Now script sells stocks before buys to be able spend newly acquired cash
• Now script buys not the first stock with suitable conditions, but most profitable
• Now script able to buy more already existing stocks, if they are most profitable
• Script cured from volatilityphobia, futhermore volatility considered now as good property since stocks with more volatility usually more profitable
