Entry based on exit signal type

POS= 16;
List=IIf(InWatchListName("List 1")==1,1,IIf(InWatchListName("List 3")==1,2,IIf(InWatchListName("List 2")==1,1,00)));

Buy= (exittype2==0 and C > MA(C,20 )) OR (exittype2==1 AND C > MA(C,200)) ;

exittype1=C < MA(C,20);
exittype2= C < Ref(LLV(C,20),-1);

Sell=exittype1 OR exittype2

if trade is exited by exittype2 i want it to be entered on another condition

how can i achieve this
