Possible exploits for the new trading system

Hello,

thanks for the awesome reveal, once again.

I hope some GGG dev will notice this topic and can give some feedback about the new trading system. While i think asynchronous trades are a very nice feature, i am worried about some possible exploits. Here are my main concerns:

1. What happens if i secure the top 20 items i find in search (only securing them, not finishing the trade)? Is this possible or only one item per character at a time?
2. If point 1 does not work, what about botters making 20+ accounts to lock the best offers? Can't they just knock out offers this way?
3. Secure one item but get the opportunity to buy other items as well. How does this work? Are the other items secured as well, basically locking the whole merchant or are they free for all? If so, how does this deal with race conditions? is this just some first come first serve, where an items suddenly vanishes from the stash or how do we have to imagine this panning out?

Update: Nevermind, the Q&A just more or less confirmed that "Secure" won't actually lock an item, so no exploiting here.


Best regards
