# Rank Calculate

The rank will be calculated at the time you buy / sell \$MLM token.
For example:
• Alex, Bob, Carl and Dave were friends and join the Multi Finance Protocol.
• At the time they bought \$MLM, the rate is 1 \$BNB = 100 \$MLM.
• And they bought 300 \$MLM, it means they got rank 3 and they could enjoy upto 3 levels of their below trading fees.
• Unluckily, after a few days, the bear market came and the rate was 1 \$BNB = 200 \$MLM.
• Alex was a diamond hand, he didn't sell any \$MLM, so his rank was still level 3 and he could enjoy his 3 levels trading fees in \$BNB without any worries. So he survived in the bear market!
• Bob was a paper hand, he sold 33% of his \$MLM, so he had 200 \$MLM left; When he sold his \$MLM, the Multi Finance system re-calculated his balance and checked that he only had 1 \$BNB of \$MLM, so his rank decreased to level 1, he could only enjoy 1 level of below trading fees. Poor Bob!
• Carl decided to DCA. He bought 100 \$MLM so he had 400 \$MLM; The system also re-calculated his balance and checked that he only had 2 \$BNB of \$MLM token. His rank should reduced to level 2, but no, the system would not re-rank the buyers and hodlers. Carl still had 2 \$BNB of \$MLM and rank 3.
• Dave was a whale-being. He continued to buy 500 \$MLM and he had 800 \$MLM (equal 4 \$BNB); After re-calculated the balance, the system would increase the rank of Dave to level 4.
