Pre-Trade Firewall for Prop Firm & Independent Traders
Stop the bad trade before you take it.
A 30-second check before every session tells you Proceed, Caution, or Stop — based on your state, not your setup.
14 days free · No card required · Your trading data stays private

PROCEED
You may proceed with normal trading.
Nothing flagged today
All seven answers came back clear. Trade your plan, inside the limits you set on Day One.
A good session should feel boring. If it starts to feel exciting, that's your cue to slow down, not speed up.
Illustrative sample of the real result screen. Proceed when you're clear. Caution when something's off: one trade at most. Stop only when two in-the-moment risks stack up.
Your strategy isn't the problem. Your state is.
Built for traders whose plan works on paper and breaks on certain days — after a loss, after a big win, after a bad night.
The process
How it works
Check
Before the session
Seven questions, thirty seconds, then Proceed, Caution or Stop, with the reason behind every flag. After a few weeks it knows your history too. It all starts with a 10-minute Day One: your leak and your limits.
The Firewall Check →Hold
During the session
Every exit you log starts a pause, longer after a loss, and reaching a limit locks the day. Want to break a rule? One button, 90 seconds first. In Session Mode, a short check-in every 30 minutes.
During the session →Close the day
After the session
Two minutes of Daily Close, then the Coach's debrief and one thing for tomorrow. Over the weeks, the Mirror shows which states actually cost you, in your own numbers.
The Mirror →After a few weeks
You stop guessing why the bad days happen.
Built from your own logs, not from general advice.

Illustrative sample — every number here only appears once you have enough real history behind it. No pattern shown from luck.
Coach · after every Daily Close
One honest read of your day. One thing for tomorrow.
Written from your own logs, and it remembers what it asked of you yesterday. Tomorrow's one thing is waiting on your Firewall in the morning. It never tells you what to trade.
Where you are
Yesterday you committed to starting the Post-Loss Protocol after any loss. You did, twice. Four clean days out of five this week.
What happened
Two losses, −1.4R, and you stopped at your limit instead of looking for a third trade. For a Get-It-Back Trader that's the whole fight, and today you won it. A red day with every rule followed is a good trading day.
Tomorrow
If the first trade loses, take the full 20-minute lockout before you look at a chart again.
Illustrative sample.
“Stop being the gambler in the casino. Become the owner of the casino.”
Five stages, gated on process, never on P&L. See the stages
Plus optional tools for the traders who want them: a trading window, position sizing, an eval-budget cap, a screen lock while a trade is open. See every feature

Why this exists
I built this because I needed it — and didn't have it. As a new trader with too much access and too little experience, it cost me six figures, and very nearly my family. This system is what I wish had stood between me and the market on the days I was the biggest risk in the room.
— Peter G., trader & founder of LAYER 0
I use it myself. My Golden Rule inside the app is “Never re-enter within 20 minutes of a loss.” Some days it's still uncomfortable. That's the point.
Is this for you?
It's built for you if
- +You have a strategy that works on paper, and you break it on certain days: after a loss, after a win, after a bad night.
- +You'll give it two and a half honest minutes a day: a check before the session, a close after it.
It's not for you if
- —You want an app that trades for you or blocks orders at your broker. It isn't connected to your broker; it works from what you log.
- —You won't log honestly. It only knows what you tell it, and a softened answer teaches it the wrong thing.

Before you start
How is this different from a trading journal?
A standalone journal only records what already happened. LAYER 0 includes a journal too — closed out daily (Daily Close) and weekly (The Weekly Close) — but adds what a journal alone can't: a verdict before the trade, not just a review after it.
How much time does it take each day?
About two and a half minutes: a seven-question check before your session, around 30 seconds, and a two-minute Daily Close after it. Everything else in the app is optional.
When does it start working for me?
The protection works from the first session: your limits, the Firewall verdict, the loss lockout and the urge check. The Coach's first debrief comes after your first Daily Close. Progress and Insights open on day 8, with a week of your own numbers. After a few weeks the Firewall starts to know your history, and a day like the ones where you usually break rules gets a Caution even when you feel fine. After 20 clean days you complete your first 20-Day Block, and only then can your size go up. All of it depends on one thing: LAYER 0 only knows what you tell it, so a day without a Daily Close is a day it can't learn from. Two and a half honest minutes a day is the whole price.
Can I override a Stop verdict?
No. A Stop holds until tomorrow — no redo, no override button. An escape hatch that runs on willpower fails at exactly the moment you'd reach for it. Caution is different: you can redo it once a day, no sooner than 15 minutes after the verdict, and only after writing down what actually changed. That reason stays in your Decision Log.
Does this work with my broker or trading platform?
Yes — any broker, platform, prop firm, or market: futures, forex, stocks, crypto. The Firewall Check runs before you open your charts and the lockout after a logged loss, so there's nothing to integrate. Honesty Audit, the trade-history cross-check, auto-detects NinjaTrader and MT4/MT5 exports; any other broker's CSV maps in about 30 seconds.
What happens after the 14 days?
Nothing, unless you choose to keep going. There's no card on file, so nothing gets charged. If you add a card during the trial, the first charge still waits until the trial ends — and a 30-day money-back guarantee covers that first payment.
