Market order have a higher fees I think, so if not in a hurry better to do this manually. If the price is already within your target range then you can trade on a higher price to filled your trade but if not and you’re confident that the market will hit your buying/selling price, then wait for it. Remember we should trade without analysis and don’t let your emotion takes over you, be more patient and trade better.
It depends.
1. If it is a limit order and you have a buy order price higher than the market price of the asset, the order would be filled immediately because it is still filled at the market price instantaneously. I mean that is still a market taker.
2. If it is still a limit order and you have a sell order price lower than the market price of the asset, the order would be filled immediately because it is still filled at the market price instantaneously. I mean that is still a market taker.
But if it is otherwise to 1 and 2 in a way that the order price is lower than the market price for buy and higher for sell order, the order will not be filled immediately and that is a market maker.
On exchanges, market taker fee is higher than market market fee.
