 [2023-01-20 11:22:11] #1 User266447 - Posts: 251 Is it possible to set an alert on a DOM? On the bottom or the top of the DOM (please see attachment) there is a summary of numbers of contracts. I would like to set the alarm when the number of contracts is equal or above i.e. 1200. Could you support me on this one, please?

 [2023-01-20 15:33:06] #2 John - SC Support - Posts: 33578 This can be done using the existing tools. The trickiest part is getting access to the Bid/Ask sums, as they are not readily available except as displayed in the DOM. To do this, you need to use two copies Bid and Ask Depth Bars with one set to display the Sum of the Bids and the other to display the Sum of the Asks. This gives you those totals as the Close of the last bar in the study. Then setup your alert(s) based on the Subgraph(s) for the Close in the Bid and Ask Depth Bars studies.

 [2023-01-20 16:04:42] #3 User266447 - Posts: 251 What shall I write in the alert section if I need a number of contracts bigger than 1200?
 [2023-01-20 17:19:13] #4 John - SC Support - Posts: 33578 If you just want to test one item (i.e. Bid total greater than 1200), then the Alert would be the following: =ID1.SG4 > 1200 Where ID1 is the ID of one of the Bid and Ask Depth Bars study and SG4 is the Close subgraph of that study. If you want to test for either condition to be true, then it would be the following: =OR(ID1.SG4 > 1200, ID2.SG4 > 1200) Where ID1 and ID2 are the two Bid and Ask Depth Bars studies.

To do this, you need to use two copies Bid and Ask Depth Bars with one set to display the Sum of the Bids and the other to display the Sum of the Asks.

 [2023-01-23 17:03:35] #6 John - SC Support - Posts: 33578 You just add two copies of the Bid and Ask Depth Bars study to a chart. Just be sure they are in different regions (one in Region 2 and one in Region 3, for example).

 [2023-01-23 18:29:24] #7 User266447 - Posts: 251 Could you provide step-by-step print screens, please? I am not very familiar with DOM.
 [2023-01-23 18:51:01] #8 User266447 - Posts: 251 or I can send you my chartbook and you can provide the necessary changes? To speed things up...
 [2023-01-23 23:18:13] #9 John - SC Support - Posts: 33578 You can not add the studies to a Trading DOM. You need to add them to a chart and create your Alert on the Chart.

 [2023-01-24 13:23:14] #10 User266447 - Posts: 251 OK. Could you record a short video on how to do it? I do not have 6 weeks to solve one single inquiry and this support goes nowhere as I have no experience with DOM and I do not know what are you saying. Even a step-by-step print screen will help. Or I can send you my chartbook and you can make the necessary changes. Please.

We recommend you contact Diana Pena as she is someone that does this kind of thing for people. If you point her to this thread, she should be able to put together what you need.
