Buy Bid / Buy Ask or Sell Bid / Sell Ask ?

[Chang]

For some reason, I cannot find detailed description of these market order types either from google search or platform documentations. Anyone can please provide some details of these order types? What is the difference with traditional market order (Buy Market or Sell Market)? What's the advantage or disadvantage of them? When I want to use them? etc.....



Thanks,

Buy ask is an aggressive order that matches the ASK where you expect a quick execution.

Buy Bid will enter a buy order to match the bid which requires the sellers to lower their offers to hit your bid. Less aggressive and might not get an execution.

Both are limit orders and not "market orders."
