People avoid looking for good exits because exits do not give them control over the market. However, exits do control something. They control whether you make a profit or a loss, and they control just how big that profit or loss will be. Since they do so much, perhaps they are worthy of a lot more study on the part of most people.

ColumnA: B/Since
BarsSince(Cross(Mov(CLOSE,50,S),Mov(CLOSE,200,S)));

ColumnB: -2 Bars
Bars:=LastValue(BarsSince(Cross(Mov(CLOSE,50,S),Mov(CLOSE,200,S))));
Abs(LastValue(Ref(Mov(C,50,S),-Bars-2)- Ref(Mov(C,200,S),-Bars-2)));

ColumnC: -1 Bar
Bars:=LastValue(BarsSince(Cross(Mov(CLOSE,50,S),Mov(CLOSE,200,S))));
Abs(LastValue(Ref(Mov(C,50,S),-Bars-1)- Ref(Mov(C,200,S),-Bars-1)));

{Recommend you use minimum 500 bars, preferably more}
