It seems you misunderstood the point. So let me re-phrase as per what you said: > They set the price for you >> Will coinbase honor the price they set when order is placed ie if it is set $19700 then will it let me buy 0.1 BTC at this price? In which case, the spread question is only about whether there is a huge spread between the display (average) price and their set price.
