It works. But apparenty one of AND condition parts are not met.
Always use the exploration to find out why your code does not work.
Display every column as exploration
BTW: lots of redundancy in your code. IIF not needed. Multiplicaiton not needed.
The code below will allow you to find the answers yourself. Run as exploration and see
x = H == HHV(H, 30);
y = - BarsSince(x);
Buy1 = x AND AccDist() > Ref(AccDist(), y);
Buy2 = x AND AccDist() > Ref(AccDist(),-5);
PlotShapes( shapeUpArrow*Buy1, colorGreen, 0, L, -10 );
PlotShapes( shapeUpArrow*Buy2, colorBlue, 0, H, -10 );
Filter = 1;
AD = AccDist();
AddColumn( x, "x" );
AddColumn( Ref( AD, y ), "Ref(AD,y)" );
AddColumn( AD, "AccDist" );
