MarketXED sends trade-related SMS only in the regular U.S. cash session: 9:30 to 16:00 Eastern. The window is a focus rule, not a marketing flourish. After-hours prints, weekend narratives, and pre-market spikes do not get to buzz your pocket. Delivery still depends on Twilio, your carrier, and a correct phone on the account. Texts are alerts, not advice, and not an order.
Why the window is tight
Most of the playbook assumes regular-hours liquidity: limitable spreads, a session close, and a time stop that can actually be honored. A 2 a.m. headline is a different microstructure. Restricting SMS to RTH keeps the alert aligned with when the committee is allowed to fire actionable session risk. Pre-market can still exist on a chart; it should not page you.
- 9:30 ET: session open; alerts may start.
- Through the day: only if a setup clears gates and SMS is enabled.
- 16:00 ET: window closed; no “one more ping.”
If the market is closed or it is the weekend, there is nothing honest to text about a live entry. The copilot should say the session state instead of implying a quiet edge.
Account rules still win
A text does not add day-trade capacity. If you are against PDT or unsettled cash, ignore the ping or you will spend Monday talking to a broker. Cash accounts in particular should treat an alert as optional information, not a mandate to recycle unsettled funds. The playbook’s hold clock is still the clock even if a second text never arrives.
Learning-only names should not become a text. If they do, treat that as a bug, not a gift. The product stance is: no alert, no implied ticket, when the committee is only collecting a label.
Deliverability, in practice
Confirm the number in User Info. Do not block the sender. Carriers drop messages. If nothing arrives, check the admin/user SMS log rather than re-entering the same setup. Do not give OTP codes to anyone who DMs you about a “failed alert.”
A day pass can include the alert channel for that unlock; it does not extend the clock past 16:00 ET. If you want overnight messaging, that would be a different product. This one is RTH-only on purpose.
How to use a text
Open the app, read the card (entry, stop, target, exit time), and decide. Do not buy from the preview line alone. If you cannot look at the card before the time stop would already be stale, you already missed the experiment. Silence after 16:00 is a feature. Use it.
OTP versus signal texts
Login codes and signal alerts can share a vendor and still be different objects. Never send an OTP to anyone who claims they are support. Never treat a signal SMS as a login. If you did not request a code, ignore it. If you requested a code and got a ticker instead, you are on the wrong mental tab; open the app.
Quiet days will be quiet. That is cheaper than a pager. If you want a heartbeat, look at the in-app poll time, not a custom “test ping” habit that trains you to need noise. The window closing at 16:00 ET is the daily off switch. Use the evening for labels and the next filter, not for inventing overnight SMS.
Worked example: 15:50 ET ping
A text arrives at 15:50. The playbook clock may already be shorter than 90 minutes because of the cash close. Open the card. If you cannot attach a stop and honor an exit before 16:00, pass. The window closing at 16:00 is not a dare to squeeze one more ticket. It is the off switch.
If you trade from a desk where the phone is in another room, SMS is the wrong channel. Use the app. A text you honor ten minutes late is a random market order with extra steps. The 9:30-16:00 ET box assumes you can open the card while the clock still has meaning.
