Yep, cancel all existing limit orders to restore your full buying or selling power. RH you use limits only when it's moving. Set the limit half a cent or so above or below when buying or selling, and dont use entire balance, I think there is 1/2% trading fee, seems I saw something about that. Market orders are collared with a 5% range on the amount to buy or sell. If it's moving fast, it will bounce outside the range, and error of not enough buying or selling power. The limit order still executes at the best possible price at the moment you enter the order.
