### Comment:
'Market' seemed implied when you brought up RH, which I assume fills at the closest market price regardless of the gap in order to fill your order as soon as possible. 
  
 Alternatively TW is very precise, which seems to confuse people coming from other brokers that expect a trade to execute immediately. When an underlying is $0.15 wide on the bid/ask price of course your trade won't execute if your trade gap is only $0.02.

### REPLY:
A “market” order in RH is actually a limit order with 5% headroom
