Modify my limit price

To modify an order quantity you may choose to leave the old order up and enter a new order for the difference.  This retains the original order's position in the order matching queue.

To modify an order's limit price you must kill the old order and enter a new replacement.

Given sufficient available resources you can put the new order in before killing the old, but this runs a risk of trading both.

Why can't I modify an existing order's price?

You cannot modify an existing order's limit price because you must surrender your position in the order board queue. 

Think of it the other way around.  It would be unfair if someone else could see you offering a better price, match your price, and in so doing jump ahead of you in execution priority by virtue of being an earlier order.  Clearly they must go to the back of the queue at their new price.

The procedure

Step 1.	LOGIN .  Bring up your orders from the  HISTORY > ORDERS  screen.  Open orders are shown at the top of the first page of results. Click on the order you want to change to display that order's details in the orders panel.
Step 2.	If the order is still active the  KILL ORDER  button will display.  To replace it you must first take the order down from the order board.  Press  KILL ORDER .
Step 3.	Click the  BUY  or  SELL  tab on the top of the order panel. Re-enter your order from the beginning, applying the new values.  Then press the  BUY/BID  or  SELL/OFFER  button at the bottom of the order panel, review your order and press  CONFIRM  at the bottom of your order panel. If you need to remind yourself about entering orders in general go to our Buy Whisky page.
