Trailing stop order Bitstamp only absolute?

Hey guys,

I was wondering: If I understand the tutorial on the Bitstamp website right, they only offer an absolute trailing stop order. Is this correct?
Thanks.

For example: Market price of bitcoin is $480 and you placed a Stop Sell Order at $450, which is in our case $30 below the current market price. Suppose price of bitcoins suddenly increases to $550. You are now in chance of “locking in” even bigger profit by manually repositioning your Stop Sell Order to higher price.

Repositioning your Stop Order can be done automatically for you by enabling “Trailing Stop” function. In our case Trailing Stop Order will automatically reposition active Stop Order if price of bitcoin increases while maintaining spread of $30 between the bitcoins spot price and Stop Order.
