Some people don't want resting orders to be visible. NinjaTrader will not send your limit order to the broker until the price is touched. It might be dependent on the platform rather than the broker. But still, can we have the definite word whether Schwab's platform can do this?
It sounds like you might want Stop Limit Orders in both directions, One Cancels the Other. https://www.schwab.com/resource-center/insights/content/stock-order-types-and-conditions-overview https://help.streetsmart.schwab.com/SSCentral/1.0/Content/Advanced Order Types.htm
