| What is CryptoBot? | ||
| ======= | ||
|
|
||
| CryptoBot is a very simple automated PHP-based cryptocurrency trading bot for the Bittrex exchange. | ||
| It uses the wrapper class from Edson Medina (https://github.com/edsonmedina/bittrex) | ||
|
|
||
| The trading bot works on a conditional model (if this then that), and does NOT include any kind of trading analysis. | ||
| It simply sells after a desired procentual price increase and buys after the price falls again. | ||
|
|
||
| Requirements | ||
| ======= | ||
| * 2-FA enabled on your bittrex account, so you can add API-access to your profile | ||
| * Any kind of webserver, where the script can be run (PHP is obviously required) | ||
|
|
||
| Usage | ||
| ======= | ||
|
|
||
| * Edit the bot.php | ||
| 1) Change the values of the API_key and API_secret variables with the ones you've got from your bittrex account | ||
| 2) Change the values of sell_percentage and buy_percentage. Those are per default "10", that means the bot will buy after the price fell for 10% and sell after it has 10% profit from last buy) | ||
|
|
||
| * Create a cronjob | ||
| Either create a cronjob with "crontab -e", and let the bot run every 1 minute or 5 minutes or | ||
| Use a free service that calls your script every X minutes | ||
