Short answer: I was thinking filtering the “past orders” table only (not the graph).
In the graph and in the (pending) limit orders table, small orders are naturally filtered - visually.
However, in the “past orders” table, which get displayed in real time, every order occupies 1 line, however big or small. Meaning your 100 BTC market buy order will soon disappear because of the 50 sub-0.01 BTC orders that follow!
Big orders are precious information to traders (day traders please confirm) and thus I believe it could be useful, all the more than it’s a feature I haven’t seen implemented in any other exchanges. A good way to stand out!
