Why won't Cover 8 Sell when the Market has reached the sell parameter?

Cover 1, 4 and 8 are Average positions.

 

Covers 2, 3, 5, 6 and 7 are Independent positions.

 

If Cover 4 is reached, Cover 2 and 3 are no longer Independent positions and apart of Cover 4, 3, 2, 1 and Initial Buy Average positions.

 

If Cover 8 is reached, Cover 5, 6 and 7 are no longer Independent positions and apart of Cover 8, 7, 6, 5 4, 3, 2, 1 and Initial Buy Average positions.

 

The Average positions only sell when AV Price is reached, plus 1.5% and Retrace 0.5%.
