"buy ask" & "sell bid" = "buy market" & "sell market" bad math things that are different are not the same.
If they were truly the same thing then trading platforms would not have separate buttons between the two. I.E. Buy Market = a market order. Buy Ask = Place limit order to buy at best asking price. So the difference is the order type.
that's not the same thing at all LOL when shorting, it's far better to get a sell bid fill, not sell ask (or sell market). especially when throwing out limit orders. probably why the OP asked as i'm curious on how to add them to the web version on NT too
