buyers have lowered quite a bit and given there were 2 sales at 100~ i'd include that in the range here and go 100 - 160 to balance it out

Adding to the above that you should always be careful rejecting the majority of sales based on buyers. Buyers tend to fluctuate a lot. Even if they still buy at ~100, if the majority sells to them, then they are definitely still part of the common trading point; its not uncommon for buyer overcutters to become so high that everyone that has one available will simply unload them to a bot, thus vacating the market and rendering the buy orders pointless.

In this case, that did not happen, but two simply sold for around this value in a market that may not even have had buyers at that value, which is always something to consider.
