Order Options
Where can I choose order options?
Post Only (Maker Only)
If you select "Post Only" when placing a limit order, your order shall only exist as a Maker order and will not be matched with an existing order in the order book. If your order has been executed instantly (as a Taker order) due to the order price (for instance, your buy order is placed at a higher price than the market price), it will be canceled automatically by the system.
Fill Or Kill (All Deals or Cancel Now)
If you select "Fill Or Kill" when placing a limit order or market order, it will only be fully executed. Otherwise, it will be canceled entirely.
Immediate Or Cancel (Deal Now and Cancel Remaining)
If you select the "Immediate Or Cancel" feature when placing a limit order or market order, any part of the order that is not immediately filled will be canceled immediately. Example: A user wants to buy BTC, assuming that the order queue at this time is as follows:
| Price (USDC) | Amount (BTC) | |
|---|---|---|
| Sell 5. | 18,745.75 | 1 |
| Sell 4. | 18,739.41 | 1 |
| Sell 3. | 18,737.40 | 8 |
| Sell 2. | 18,737.37 | 100 |
| Sell 1. | 18,737.25 | 156 |
| Buy 1. | 18,726.93 | 415 |
| Buy 2. | 18,726.80 | 374 |
| Buy 3. | 18,723.44 | 500 |
| Buy 4. | 18,720.00 | 2 |
| Buy 5. | 18,718.29 | 13 |
(1) If a user wishes to enjoy the Maker fees, he/she may choose the advanced limit order, and set to "Post only". If the user buys at 18,726 USDC, the order will not be filled with those in the queue; the order will only be placed successfully when the user is a Maker. If the user buys at 18,737.25 USDC, the order will be filled with those in the queue; the order shall be canceled instantly when the user is a Taker.
(2) A user selects "Fill Or Kill" with the buy price at 18,745.75 USDC and the quantity at 300. At this point, the total quantity of sell orders at 18,745.75 and below shall be 266 (1+1+8+100+156). Once all 300 buy orders have been filled with all eligible sell orders, it shall be left with 34 (300-266) unfilled orders. As such, the order itself shall be canceled. If the user buys 266 or less, the order shall be fully executed.
(3) A user selects "Immediate Or Cancel" with the buy price at 18,745.75 USDC and the quantity at 300. At this point, the total quantity of sell orders at 18,745.75 and below shall be 266 (1+1+8+100+156). Once all 300 buy orders have been filled with all eligible sell orders, it shall be left with 34 (300-266) unfilled orders, only the 266 sell orders shall be executed while the remaining 34 unfilled ones shall be canceled.
