Positions and orders on your (subscriber's) account are executed as market (at market price) at the moment of their execution on the trader account. Due to this reason and the number of orders, you can buy or sell a coin at a different price than the trader.

Coinmatics places the order on average 2 seconds after execution on the trader's account. The execution itself depends on the exchange and market conditions. In other words, it can be affected by the current market.

The more orders are placed in one direction (buy or sell), the greater the difference in price of a trading pair with a trader will be.
