On January 23, 2018, we will be changing minimal order volume and price precision on most of the Markets at CEX.IO. These changes will make orders processing more efficient and allow us to improve the quality of the provided service. They are aimed at reducing high-frequency, low volume order trade at or near the current market price. Such activity impacts the performance of trade engine considerably while bringing very little liquidity to markets. Care should be taken by those who use bots or API for trading activities. Please adjust the algorithms using below information for the orders to be processed without flaws.
What’s in scope:
1. Reducing the number of decimal places for a specific trading pair.
Price precision will be reduced on most CEX.IO markets. Price precision is the number of decimal places allowed in the price of a placed order. Reducing this number of decimals will considerably improve the performance of the trading engine by eliminating microscopic price fluctuations and thus, the number of calculations our trade engine has to do every second. As a result, our trade interface should become more responsive, and you will be able to place orders faster. For example, you were able to place orders with the precision of up to 0.01 USD on BTC/USD market. Now precisions up to only 0.1 USD will be supported for this pair.
2. Сhanging minimum values for placing orders.
Because of the growth in the price of most coins lately, it became increasingly difficult for traders with certain trade strategies to effectively enter our market, as minimum order values were too high. We will change and standardize minimal order volume for you to be able to trade more efficiently with your money. The minimal order will be equal to around 20 USD for the pairs that include fiat. For the cryptocurrency pairs, the estimation equates to approximately 0.001 BTC. Please note, that these values are approximate and are represented in quote currency (e.g you will be able to buy approximately $20 worth of Bitcoins when changes take effect). This is done in order to find a common denominator that can be easily understood by all users. On trade engine itself, orders are placed in base currency.
