You can add multiple conditions to both price and trendline alerts. For example, you can set a price alert where price has to be greater than certain $ amount AND the daily volume has to be greater than 1 milllion.

Set a price or trendline alert the same way you would for a single condition alert. Then, in the create alert panel click on + Add Condition

You can then search for the data point you want to add as the second condition. In this example we have added daily volume greater than 1 million.

In order for the alert to trigger, ALL conditions must be met.

You can add up to 5 additional conditions to your alert including Yes/No conditions, percentages, dollar figures or integers. To add another condition, click the + Add Condition button again and searching for the data point you want.

To remove conditions, click on remove condition
