Yes sir, you are absolutely right.
When using an indicator in TradingView, you generally need to create two separate alerts because indicators do not provide the {{strategy.position_size}} variable like strategies do.
Step 1:
Create and configure a Custom Bridge in AlgoDelta if you don’t already have one.
Configure both the Up Side and Down Side executions as per your requirements.

Step 2:
Copy the webhook URL from the Custom Bridge using the yellow copy icon.

Step 3:
Open TradingView and apply your indicator on the chart. Let’s say we apply the “UT Bot Alerts” Indicator.

Step 4:
Create the first alert for the Upside execution.
Configure it as follows:
-Condition:
Select your indicator
-Crossing:
Crossing Up
-Value:
Select the value or plot generated by your indicator
-Trigger:
Once Per Bar Close
-Expiration:
Keep it as per your requirement
-Message Section:
-Alert Name:
UP Alert (You can put the other name also)
-Message:
UP (Always in capital letters)
Click on “Apply”.

Step 5:
Go to the Notification section.
-Enable Webhook URL
-Paste the webhook URL copied from the Custom Bridge
Click on “Apply”.

Then click on “Create”.

Step 6:
Create another alert for the Down Side execution.
Keep all the settings the same except:
-Crossing:
Crossing Down
-Alert Name:
DOWN Alert
-Message:
DOWN
Then click on “Create”.
That’s it.
Now whenever the indicator generates an Up signal, TradingView will send the message UP and the Upside execution configured in the Custom Bridge will be executed.
Similarly, whenever the indicator generates a Down signal, TradingView will send the message DOWN and the Downside execution configured in the Custom Bridge will be executed.
This is the standard and recommended approach for connecting TradingView indicators with AlgoDelta’s Custom Bridge.
