The commitment device for traders · opens 23 November 2026
Rules you can't quietly undo.
Set your trading rules while you're calm. Tighten them in one tap. Loosening waits 24 hours, or needs your partner. Mast opens on 23 November 2026, in English and French.

Loosening: 24h delay, or approval from @partner
Set on 3 Nov, while calm.

What Mast can do differs by platform. Read the exact level for each one below.
What you'll get at launch
Tighten now, loosen later.
One rule set, every account.
A witness.
You know your rules. The trouble starts at −$180.
You wrote your daily loss limit on a calm morning. Then the market took two trades from you, and the limit became a number you could edit. Most platforms let you raise it in a couple of clicks. Most “locks” end with the session and cover one account. Your journal shows you the damage the next day.
“my biggest problem has never been finding entries — it's stopping.”
“If your loss limit is set at -$200, and you're -$180… you can just change the DLL”
“The plan-making version should be allowed to protect the account from the 2am version.”
This isn't about willpower. It's about when you decide.
We don't sell brain chemistry. Here is what published studies show, and what we built because of it.
| Finding | What Mast does about it |
|---|---|
Professional futures traders who lost in the morning were about 15% more likely to take above-average risk in the afternoon. | Your rules are set before the session, and a loss can't loosen them during it. |
When people can edit their own limits, most edits go up. In a casino budgeting programme, the median monthly budget went from $300 to $1,000 among those who changed it. PlayMyWay evaluation, Massachusetts Gaming Commission, 2017 · gambling analogy | Tightening is instant. Loosening waits 24 hours or needs your partner. |
When a limit is imposed from outside, behaviour changes. A 2010 US leverage cap cut affected forex traders' volume by 23% and their losses by about 40%. | You choose the limits yourself, then Mast holds them for you. |
More than half of the people on the UK's gambling self-exclusion scheme chose the longest option, five years. GamStop, July 2026 · gambling analogy | Locks can last 1 week, 1 month or 3 months, not just one session. |
A short pause before opening an app cut openings by 57% over six weeks. Grüning et al., PNAS, 2023 · phone-use analogy | Even where nothing is blocked, a warning, a delay and a witness still change what you do. |
Studies from gambling, savings and phone use are analogies, not proof about trading. Sources are linked under each claim.
Three steps, set once, while calm.
- 01
Set your rules.
Daily loss, max trades, cooldown after a loss, trading hours, max size. Start from a template or write them in plain words; we turn them into precise rules and show you exactly what we understood.
- 02
Connect your accounts.
OAuth, scoped API keys or read-only access. Never your trading password. One rule set applies across every linked account and firm.
- 03
Choose how hard it is to undo.
Pick a loosening delay (12 hours to 30 days), invite an accountability partner, or commit to a lock of 1 week, 1 month or 3 months.
What we can stop, and what we can't.
Some tools in this space say “no bypass”. That isn't true for any of them, including us. Every platform has a public page with its exact level and the ways around it.
The ladder
| Level | Name | What happens |
|---|---|---|
| N0 · nudge | Nudge | An alert or a warning. You can ignore it. |
| N1 · client friction | Client friction | A button is disabled or covered on your screen. It can be bypassed. |
| N2 · closes after fill | Close after fill | Your order goes through, then gets closed. Works while the software runs. |
| N3 · native server lock | Native server lock | The platform itself rejects your orders until the lock ends. |
| N4 · pre-trade block | Third-party pre-trade block | A broker plugin or back-office key rejects the order before it executes. |
| W · witness | Witness | Read-only view of all trades from any device. A trade that breaks your rules alerts your partner and hits your score. |

“If you can add an EA, you can remove it.”Built for the moment you'd rather not have rules.
Delayed loosening
Raise a limit and it waits 24 hours (you choose 12 hours to 30 days). Your 9:00 self decides; your 15:47 self can only request.
Accountability partner
A friend, mentor or educator approves or refuses loosening with two-factor authentication. They get a short weekly summary, not your P&L, unless you choose to share it.
Multi-week locks
1 week, 1 month or 3 months. Platform locks stop at the end of the session; yours don't have to.
One rule set, every account
Same rules across firms and platforms, on up to 5 accounts with Core (10 with extra accounts). Strictest rule wins.
Bypass detection
A trade from an unlinked device, a removed EA or a revoked key: your partner is alerted, the event is logged, and your score reflects it.
Panic lock
One tap from the web app, Telegram or the MT5 chart: lock every account now, for the rest of the day. Set up while calm, used when not.
Tilt detection
Re-entry minutes after a loss, size growing after losses, trade frequency far above your norm. Clear rules, no black box. They can tighten your rules automatically, if you set them to.
Telegram bot
Alerts, check-ins, partner approvals and the panic button, where you already are.
Tamper-evident log
Every rule change, lock and bypass goes into a hash-chained log. Your coach can trust it; so can you.
Commitment cards
Share “Locked: 3 trades a day for 30 days, witness @mentor”. Your public promise, with proof attached.
Weekly review
A short written review of your week, built only from your own numbers.
Self-exclusion pause
Step away from trading for 7 days to 6 months, with no early exit and links to support resources.
A score for keeping your word. Not for your profits.
The Mast Score (0–100) measures whether you did what you promised yourself while calm. A losing trader who keeps every rule can score 95. A winning trader who revenge-trades scores low. Luck can't inflate it.
- Every point is explained: tap the score to see which event moved it.
- Verified, Partial or Self-reported, shown next to the number.
- Days you don't trade never count against you.
- Streaks, heatmaps by hour and weekday, and what breaking your rules cost you, always shown as an estimate with a range.

Questions traders ask first
Does Mast block my trades?
It depends on the platform, and we say exactly what happens on each:
- TopstepX: You set the lock, Mast checks it.
- MetaTrader 5: Mast closes and witnesses.
- Binance, OKX, Bybit: You enable the exchange cooling-off, Mast watches.
- Hyperliquid: Mast watches and alerts.
Each platform page lists the level and every known way around it.
Can't I just uninstall it or revoke access?
Yes. Nobody can stop you removing software from your own computer, and we won't pretend otherwise. What we do is make it visible: a removed EA, a revoked key or a trade from an unlinked device alerts your partner, goes into your log and lowers your score. Where the platform's own lock is on, it stays on the platform's side until it ends.
What if I trade from my phone?
On Tradovate, the limit lives on Tradovate's servers, so it applies on your phone too. On TopstepX and the exchanges, the same is true once you've switched their lock on. On MT5, the EA runs on your PC or VPS: the witness sees the phone trade and your partner is told.
Do you need my trading password?
No. We use OAuth, scoped API keys and, on MT5, the read-only investor password. We never store trading passwords. Tokens and keys are encrypted.
Do you place trades on my account?
No. Our servers never open trades. On MT5, closing is done by the EA on your own computer or VPS.
Can I use it with my prop firm?
Mast doesn't log into your account and doesn't trade for you. It uses the connection types each platform offers. Firms set their own rules on third-party tools: when you connect an account, Mast asks for your firm first and only offers the levels it allows.
Decide calm. Trade tied.
