Notes

The tick size change applies only to the SGD market and does not affect the BTC or USDT markets.
To apply the new tick sizes, all unfilled orders in the SGD market will be canceled at the start of the server maintenance for the tick size adjustment.
If an order is placed that does not match the tick size, the following error may occur (invalid_price_bid, invalid_price_ask)

{
  "error": {
    "name": "invalid_price_bid",
    "message": "The price unit has not been input correctly. Please check it and try again."
  }
}
