Managing your size

Once a bidding order is created you can manage how many active bids are remeaning in the below screen:

The cap and remaning are going to be equal at the start, however, remaning will drop each time a bid is accepted. If your remaining becomes 0, there will not be any active bids remaning.

If you don't want to to close & re-open orders, you can increase your cap with will also increase your remaning bids. In the below picture I increased my cap to 10 in order to have 5 active bids again.
