Web Coins Alarm - PHP & JS

Hello I am Seyda Bozkurt, I have been working in software for 5 years and today I wanted to share this project with you.

The purpose of this project is to alert the Coin to the value of the stock market.We can set the upper and lower sales limits.
Alarm is running low and upper limits.The alarm consists of an audio file, if you do not hear the alarm or forget it, it will continue to play in 20 seconds.Using the Bittrex API system, we can monitor the data instantly.I think it's a simple and fun project.as an example, I used BTC-STEEM.Install the project on the virtual server and do not forget to upload the database file to MySql..I'm waiting for your comments
