Derek

The Overthinker

"Hesitates on winners, revenge trades losers. Knows his rules but can't follow them in the heat of the moment."

Marcus

The Overtrader

"Takes 47 trades when his rules say 5. Profitable strategy destroyed by undisciplined execution."

A Different Approach

We Don't Document Your Mistakes. We Prevent Them.

Traditional journals record the aftermath. Prevyu intervenes before the trade happens.

Post-Trade Journals

The old way

  • Record what went wrong after the damage
  • Feel guilty about the same mistakes
  • Promise to do better tomorrow
  • Repeat the cycle indefinitely

Prevyu Pre-Trade Checkpoints

A better approach

  • Check BEFORE you click buy or sell
  • Get GO/WAIT/NO-GO based on YOUR rules
  • Trade with confidence or walk away
  • Build discipline through intervention

Three Signals. Zero Ambiguity.

GO

All Systems Aligned

Your setup matches your A+ criteria. Execute with confidence.

WAIT
