How to use the alert system:
1. Set the desired value for BTC and ETH that you want to be alerted for
2. Set an alert on the indicator by clicking the three ellipses and then "Add Alert"
3. Set the alert to go off if the value of the indicator is greater than 0.
The example is of BTC using an alert of $10,000 and an alert of ETH at $2,000 (untriggered)
