Is it possible your limit order doesn't get filled even if the price hits it?  Asking for a friend.

Extremely rare but possible if it's a low volume ticker. Robinhood definitely does put you way behind the queue for orders. 
  
 That's assuming if it hits your limit target and then shoots above past it. If it goes below your limit target you 100% had your order filled.
