with 10 crossing above 20 // and bars with 10 crossing below 20;
P4 = ValueWhen( Crosses, WMA10 ); // value of WMA when cross occurs
P3 = ValueWhen( Crosses, Ref( WMA10, -1 ) ); // and 1 bar before cross
P2 = ValueWhen( Crosses, Ref( WMA10, -2 ) ); // 2 bars before
P1 = ValueWhen( Crosses, Ref( WMA10, -3 ) ); // 3 bars before
