Trailing Stop

How can I integrate a trailing stop with a stop order?

What I am trying to do is place a stop order, then a trailing stop if the next bar is higher than the previous bar and a new stop loss that is 10 ticks below the new high for long positions. This would execute on every new bar close. And, obviously, the opposite for short positions.

Many thanks in advance.
