Sure we can help. What condition should be met? The code for adding arrow can be as follow

ObjectCreate("OBJ"+Time[0], OBJ_ARROW, 0, Time[0], SomePrice)

Unless of course you have the condition met twice or more within the same bar,  then you will get an error as you are trying to create an Object that already exists and it will overwrite the current Object with the same name.

Use a variable to hold an index count,  maybe int ArrowNumber;  use this variable as part of the arrow Object name, each time you draw an arrow increment this variable then all your arrows will have unique names.
