ExRem is great for charting and for use on intermediary variables. But, it can interfere with the backtester and Tomasz recommends not using it for Buy/Sell/Short/Cover arrays for that reason.
http://finance.groups.yahoo.com/group/amibroker/message/125451 As an alternative, you can use the Cross function rather than the relational operators '<' and '>'. BuyCond1 = Cross(EMA( Close , 15 ), EMA( Close , 100 )); That way you don't end up with the redundant signals in the first place.
