The currency in orderbook should be the same as exchange. And avoid ambiguities, Switch between base and quote currency will not be supported.
Instead of it, I improve the 'estimate trading' tool, click the order will quick fill the amount to estimate trading.
Actually the
Volume Currency can be switch to Base(DOGE) or Quote(BTC).
Maybe do the same, optionally, to turn the
"Orderbook Currency" to Base(DOGE) or Quote(BTC) ?
