Effective Wednesday August 30 around 6 am UTC (Tuesday August 29 around 11 pm PT) we will be reducing the allowed decimal place precision for placing orders in all trading pairs. Below is a list of all trading pairs showing the new allowed number of decimal places for each pair. For example, 2 decimal places will be allowed for bitcoin-USD (XBT/USD), meaning that you can place an order for $4,350.01 but not $4,350.001. Trying to place an order with more decimal places than allowed will result in an error and the order will not be created. If the “%” option is used to specify order price, the result will be truncated (rounded down) to the maximum allowed decimal place.

Reducing the price precision will help reduce extraneous activity in the order books as traders continually jump in front of each other by a very small fraction, resulting in a higher volume of canceled (unfilled) orders. We have received many requests from clients for this reduction and it will help reduce load on the trade engine with more efficient order books.
