Need help about futures and margin ratio ?

Hey all, i need help about my open position. Well, i longed 3x isolation on NEO with 1500$, after that i added extra 1500$ position when price was lower, my average entry price fall, but my liq price rised. Also my margin ratio shows %4.10 and it's green which means i am safe. also my Maintanance margin is 64$ , Margin balance is 1.538.84$. So which is true ? will i liq when my margin ratio reached %100 or when price hit the liq price. The liq price is 72 , NEO is 99 now. but how my margin ratio shows green and %4 ?
