You can only create a pending sell stop or sell limit order for the total number of coins you own. 

For example:

if you owned 2 Bitcoin. You could create pending sell (limit or stop) orders for up to 2 Bitcoin. 

You could create 2 Sell Limit Orders for 1 Bitcoin each.  

You could create a Sell Limit order for 1.5 Bitcoin and 2 Sell Limit orders for .25 Bitcoin

You could create multiple Sell Limit orders of different amounts that add up to a maximum of 2 Bitcoin.

Any additional Sell Limit or Sell Stop orders wouldn't be allowed.

Attempting to place one or more pending sell orders for more than 2 Bitcoin would be rejected and canceled before they hit our order book.
