Newbie doing first trade here. So i want to limit buy GTC a fairly volatile equity with no stop to hold longer term. When placing the order i get an error when placing an order "too far from the last traded price". The market price is 300 and my limit buy is 230. I can do this order in my demo account on the new platform. Is it something I'm doing wrong or is there a max distance i have to be from the market price. I have limited time and don't want to be looking at screen in real time for the volatility or setting alerts. Just want to fire and forget. All advice welcomed.
