On the buyers side, there is a total of 17285205.223 RFR which is supposed to be 11.7 BTC worth, however Bittrex is saying it's worth 4.319 BTC. The same thing goes for the sellers and the other screenshots.
it is because your calculation is flawed. you are doing this:
17285205.223 * 0.00000068 = 11.75393955
BTCbut you should have done this:
(41073.529 * 0.00000068) + (19955.770 * 0.00000067) + (243789.392 * 0.00000066) + ... (x * 0.00000001) = Result
BTCand Result should be equal to 4.319
BTC. if you did that and it was not then you can say it is wrong.
