Risk enforcement for Schwab traders

Your rules, enforced when you can't.

Sentinel connects to your Schwab account and shuts you down at your own limits — position size, daily loss, time in a trade. You set them when you're thinking clearly. It holds the line when you're not.

Full Elite features for 14 days. No credit card. No Discord account needed. Cancel anytime — and the daily-loss kill switch stays free forever, even if you never subscribe.
Sentinel cannot move your money — the Schwab API doesn't permit transfers.

What that looks like on a bad day: you're down $4,200 against your $4,000 limit. Sentinel cancels your working orders and closes all three positions before you've finished deciding whether to hold on. You go home. Daily-loss kill · enforced in under two seconds

The problem

You have a plan. Then the market happens.

Every trader has rules. Position sizes, loss limits, exit points. Written down, rehearsed, believed in. And then a trade goes wrong, and those rules become suggestions.

It's not a strategy problem. It's a human problem. The same wiring that makes you competitive makes you want to fight back. One bad trade triggers another. Size goes up. Risk goes up. The hole gets deeper.

Most blown accounts aren't the result of bad strategy. They're the result of good strategy abandoned at exactly the wrong moment — when it cost real money to follow it.

Revenge trading

"I'll make it back on the next one."

Down $2,000 before noon. Instead of stopping, you double the size. The trade goes against you. Now you're down $6,000 and it's not even lunch. The logic felt sound in the moment — it never does from the outside.

Tilt spiral

One loss becomes five.

A losing trade triggers frustration. Frustration leads to a faster, sloppier entry. That trade loses too. Now you're chasing. Each loss makes the next one more likely. The account doesn't blow up on the first bad trade — it blows up on the sixth.

Sizing up to recover

"Just need one good trade."

Down on the day, you bump contracts from 5 to 20. It works — or it doesn't. If it doesn't, you've turned a manageable loss into a catastrophic one. If it does, you've trained yourself to do it again.

Can't walk away

The market closed you down. You didn't.

You knew by 11am it wasn't your day. But stopping felt like giving up. So you kept going. Three hours later, what could have been a $1,500 loss is now $12,000. The hardest trade to make is no trade at all.

Recognize any of those? That's exactly what Sentinel is for.

None of it is a strategy problem, so no amount of discipline advice fixes it. What fixes it is something that acts before you get a vote.

Security & Trust

Your account.
Your access.
Your control.

Giving any third-party tool access to your brokerage account is a serious decision. We built Sentinel with that trust in mind — here is exactly how it works, with no vague reassurances.

✓ OAuth only

We never see your password

Connecting Sentinel uses Schwab's official OAuth flow — the same mechanism used by any trusted app. You log in directly on Schwab's own login page. Your username and password never touch Sentinel at any point.

✓ No withdrawals possible

Sentinel cannot move your money

The Schwab API does not permit fund transfers. Sentinel can open and close positions, but it is technically impossible for it to withdraw, transfer, or move funds out of your account. This is a hard constraint enforced by Schwab, not a policy.

✓ Per-user isolation

Your token is yours alone

Every user's Schwab connection is stored and handled independently. No other user's Sentinel instance has any access to your account — not read access, not trade access, nothing.

✓ Enterprise infrastructure

Hosted on enterprise-grade cloud

Sentinel runs on enterprise-grade cloud infrastructure — no shared hosting, no cheap VPS, no shortcuts. Your credentials and account data are not stored beyond what is required to maintain the API connection.

✓ Fully revocable

You can disconnect anytime — from Schwab's side

You can revoke Sentinel's access directly from your Schwab account settings at any time, completely independently of Sentinel itself. You do not need to contact us or do anything on our end. Your access, your revocation.

Set the rules now.
Not after the next bad day.

Every trader who blew an account had limits they believed in. The difference isn't discipline — it's whether anything was standing between the plan and the moment it got abandoned.
