Alert(conditional statement, text alert, alert type, sound);
# # TD Ameritrade IP Company, Inc. (c) 2017-2020 # input fastLength = 50; input slowLength = 200; input averageType = AverageType.SIMPLE; plot FastMA = MovingAverage(averageType, close, fastLength); plot SlowMA = MovingAverage(averageType, close, slowLength); FastMA.SetDefaultColor(GetColor(1)); SlowMA.SetDefaultColor(GetColor(2)); def goldencross = FastMA crosses above SlowMA; # Alert Alert(goldencross, "50/200 Crossover", Alert.Bar, Sound.Chimes);
The alert script above will notify you every time there's a golden cross (the 50 SMA crossing above the 200 SMA).
Here is another one where we utilize two different alert sounds. You'll hear a chime when there is an up arrow and a bell sound when there is a down arrow.
# # TD Ameritrade IP Company, Inc. (c) 2017-2020 # input price = close; input length = 9; input displace = 0; plot AvgExp = ExpAverage(price[-displace], length); plot UpSignal = price crosses above AvgExp; plot DownSignal = price crosses below AvgExp; AvgExp.SetDefaultColor(GetColor(1)); UpSignal.SetDefaultColor(Color.UPTICK); UpSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP); DownSignal.SetDefaultColor(Color.DOWNTICK); DownSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN); # Alerts Alert(UpSignal, "Price crossing above 9 EMA", Alert.Bar, Sound.Chimes); Alert(DownSignal, "Price crossing below 9 EMA", Alert.Bar, Sound.Bell);

Useful Notes from the thinkScript LoungethinkScript Alert() function. Platform and chart have to be open. [source]
15:42 Nick Name NAG®: Stash, just to be clear. There are 2 ways to do alerts.
1) thinkScript Alert() function. Platform and chart have to be open.
2) Platform alert, found on Marketwatch -> Alerts. Platform doesn't have to be open and you can get email/SMS. You can use thinkscript, with some limitations. The Alert() function is irrelevant to a platform alert.
For the former, the types are: Alert.ONCE, .BAR, .TICK. Once = one time only, first time the condition is met. BAR = one time on each bar when the condition is met. TICK = every time the condition is true. Once you set the type, it should hold unless changed in the script or gui settings.
I am not sure how the platform alert works in this regard, those have their own rules. My testing shows the Alert() function is working correctly, other than the bug I mentioned earlier. That might have just been general wonkiness as it was within the last couple minutes of /ES before 1615. All that is to say if you are using Alert.BAR and getting multiple alerts per bar, it's not because the Alert() function is broken.
Alert for an entire watchlist [source]
By Cindy Faber TOS: to set an alert for an entire watch list, you have to create a custom chart study with alert built into the ThinkScript for the custom chart study then open a grid of charts with each containing the custom study with alert, and click on top right Symbols to select the watch list
IMPORTANT - you can detach the grid and move it until almost off your screen but do NOT minimize (chart alerts will only trigger if chart is open, even if chart is hiding near edge of the screen)
