Trailing stops - mt4 coding query

[TEAMTRADER]

In an Expert Advisor auto trader, is it possible to get a trailing stop of a fixed amount of pips/points relative to the high or low of the price following entry?
As an example, if the stop loss was 30 and the entry was long/buy at 1.3430 the initial stop would be 1.3400.
The price goes up to 1.3431 - could an EA be programmed to move the stop loss to 1.3401?
Thanks

Thanks (again) Trendie.
I can now send my EA to the coder with confidence he can code in an exact trailing stop.
