How to identify a specific object created by external indicator by candle ID?

[vish]

I have an external indicator that provides arrow signals (up and down). The arrows always appear on candle ID2. An open chart will have so many such arrows. I want to identify the arrow by candle ID (I want to place an order when the candle appears). I tried "Indicator Appear" and "For Each Object" blocks but I don't see a way to identify the most recent arrow by the candle ID. Can anyone tell me how to do this? Thanks in advance.

When you select the indicator, you can specify "Candle ID"

Yes, got it right. Thanks
