how to encode AO change color properly

i have coded the ao change color properly i think. but the problem is, the values remain even after couple of bars making the use of it as signal is still open.

here is the code of AO change color:

if(aogreen11<0 && aogreen10>0) {aobuy=true; aosell=false;}
else if(aored11>0 && aored10<0) {aobuy=false; aosell=true;}
else if(aored11>0 && aogreen10>0) {aobuy=true; aosell=false;}
else if( aogreen11>0 && aored10>0) {aobuy=false; aosell=true;}
else if( aored11<0 && aogreen10<0) {aobuy=true; aosell=false;}
else if( aogreen11<0 && aored10<0) {aobuy=false; aosell=true;}

aogreen11 is the past bar green
aogreen10 is the current bar green

same thing with the red


the problem is attached, calling the values is ok, but remains even after the bar. please help

as you can see.. there is ao up, ao down, ao down.. meaning the values should not be like that. it should be AO buy = 0, AO sell = 0

if you refresh the EA, then it will be like that, but the problem is you wouldnt be refreshing the EA every bar right?

so please help, anyway to make the values be updated every bar, thank you.

here is what it looks like when i refresh/reload the EA
