Alerts on strategies were introduced just recently in TradingView. These alerts have an alert_message placeholder which allows you to compose in PineScript very complex alerts and insert quite a lot of information in them. This is just very simple example of how they can look like.
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in publication is governed by House rules. You can favorite it to use it on a chart.
