spread trade automation

Hi
I mainly go in the market to try to flip the euribor spread for half a tick, through wathing the charts over a number of days/weeks to find ranges and try to trade the range, do many of you trade spreads through an automated system? i was looking at eurodollar spreads and they do seem to trend up/down a few ticks more than euribor... although i mainly trade euribor as i like watching a 3-4 tick range whereas on the eurodollar it is tough to try to get the range/ high lows...
