One calm surface.

Execution without detours

Buy calls or puts, trim, break even, trail, or close from one deliberate action row. Stop loss and both profit targets are live at the broker the moment you are filled.

Broker-native orders

Every exit is a real Schwab order — never a market sweep. Cancel a close and the stop plus targets go straight back on.

Risk decided in advance

Sizing and the contract cap are enforced before the order leaves your machine; a run of losers raises its own alert.

You keep the account.
The app keeps the discipline.

DS Scalper never custodies funds and never routes around you. It authorizes against your Schwab account and places the orders you configured.

One-key entry

ADD CALL or ADD PUT sizes the order from your equity rule and sends it with protection attached.

Trim and break even

Take partial size off, or slide the stop to entry, without rebuilding the ticket.

Trail on demand

A broker-native trailing stop when you choose it — cancel and the original stop and targets return.

Cancel-safe close

Closing sells at the bid and shows a CANCEL affordance. No market order is ever sent for you.

Account picker

Multiple linked Schwab accounts, switched while idle. A running session stays pinned to its account.

Live account read

Net liquidation, option buying power, and cash and sweep update beside the position.

Multi-ticker aware

Index and ETF conventions handled per symbol, down to the tick rounding on every price you send.

Mobile companion

Push notifications follow the session, so a fill or an exit reaches you away from the desk.
