How can i check if item was send in previouse offer

[mouzes1]

Here is the case

1. First trade offer I am sending from bot to user item 'CS:GO Case Key' but he does not accepting it yet

2. Second trade was requested and bot sending to user2 item 'CS:GO Case Key' but it is in trade offer 1 two.

 

3. And when some of the users accept trade offer one of offers is in "InvalidItems" state.

How can I prevent this? Is there a property in CEconItem which tell us that item is in trade already?

Something like this (dummy code):
 

offers[roundBot].loadInventory(730, 2, true, function (err, myItems) {

        for (var i = 0; i < myItems.lenght; i++) {
            if (myItems[i].isAvailable == 1) {
                itemsToSendArray.push(myItems[i]);
            }
        }
}

For that purpose, you use tradeoffer-manager's getOffersContainingItems() function.

              bot.manager.getOffersContainingItems(invItem, false, function(err, sent, received)
              {
                if (sent.length > 0)
                {
                  /* item is pending */
                }
              })
