PSYCHOLOGICAL DEFENSE SYSTEM FOR TRADERS
Stop bleeding money
on tilt.
You don't lose money because your strategy is bad. You lose because your biology hijacks your decisions under stress. HardDeck forces a pause between your impulse and your execution.
THE PROBLEM
You've been here before.
You're up $2,000 this week. You feel invincible. You double your position size. You give it all back in one trade.
You take a loss. Then another. You open a revenge trade at 3x size. Now you're down 40% and it's not even lunch.
It's 11 PM. You're staring at charts. You know you should close the app. You don't.
These aren't strategy failures. They're biological failures. Dopamine spikes after wins make you over-leverage. Cortisol floods after losses trigger revenge trades. Your prefrontal cortex — the part responsible for rational decisions — literally shuts down under financial stress.
THE SOLUTION
Three interventions. Zero bullshit.
HardDeck doesn't give you more charts, more indicators, or more signals. It gives you the one thing you actually need: a circuit breaker between your emotions and your money.
01
The Vibe Check
Before every trade, you declare your emotional state. Calm, Anxious, Euphoric, or Revenge. No hiding from yourself. The pattern becomes undeniable in your journal.
02
The Cooler
If you're tilted, the app locks you out for 3 minutes. A breathing exercise replaces the trade button. Research shows even a 90-second pause cuts impulsive decisions by 40% — we give you double.
03
Distance to Death
Instead of showing profit, we show how close you are to blowing your account. Loss aversion is stronger than greed. We use it. Green → Yellow → Red. You always know where the floor is.
THE DIFFERENCE
Every other app wants you to trade more.
We want you to trade better.

PROP FIRM TRADERS
One bad day can cost you a funded account you spent months earning. HardDeck is insurance for your evaluation.
CRYPTO & POLYMARKET
Markets that never close are a 24/7 invitation to tilt. HardDeck is the guardrail between you and a 3 AM revenge bet.
STOCK & OPTIONS
You know your strategy works. Your P&L proves it — until you deviate. HardDeck keeps you honest with your own rules.
THE JOURNAL
Log trades in seconds. See the truth in days.
One-thumb trade entry
Ticker, direction, size, price. Calculator-style numpad. Takes 5 seconds.
Check your mindset at the door
Every entry starts with a vibe check. The pattern of when you trade calm vs. when you trade tilted becomes undeniable.
Watch the survival bar, not the P&L
Your dashboard shows “buffer remaining” — how much room you have before you hit your daily loss limit. Survival first.
Let your rules do the enforcing
Set max trades per day, max risk percentage, loss limits, trading hours. HardDeck warns you before you violate them — when willpower alone won't.
WHY “HARD DECK”?
In military aviation, the hard deck is the minimum altitude. Fly below it, you die. It's not a suggestion. It's not a guideline. It's a physical boundary that keeps you alive.
We build the floor you cannot fall through. Not with more charts. Not with more signals. With friction — intentional, psychological friction that stands between your worst impulse and your account balance.
Trade with your plan, not your pulse.
The journal is free. Your funded account is not.
