Why I built PaperPad.

“I kept selling too early, sizing too big, and tracking nothing. So I built a system to fix that.”

I'm a retail trader. After years of trend trading, I realized the hardest part wasn't finding entries — it was everything after. When to add more. How much. When to get out. I was using spreadsheets, notes apps, and mental math. And I kept making the same mistakes.

PaperPad started as a personal tool. I wrote the algorithm, built the journal, added position sizing rules. Then I realized other traders probably have the same problem. So I turned it into a product.

What we believe.

“We don't trade for you.”

PaperPad is a journal, not a broker. You make every decision. We just help you track it.

“We don't hide our results.”

20 years of signals. Good years and bad years. Every trade visible. No cherry-picking.

“We don't give advice.”

Signal references, not recommendations. Your money, your decisions, your discipline.
