See what your trading mistakes actually cost you

An app idea we're validating: a simple trading journal for forex, crypto and stock traders. Import your trades, tag mistakes, and see the money each habit costs. No spreadsheet formulas to break, and no $35 to $99 monthly subscription. Join the waitlist to shape it.

What we're planning

Import, don't type

Upload your broker or exchange CSV (MT4/MT5, Binance, Bybit, TradingView exports) and your trades are in.

Mistakes with a price tag

Tag "moved my stop" or "revenge trade" and see exactly how much that habit cost this month.

Nothing to break

P&L, win rate, R-multiple and goal progress are calculated for you. No copying formulas, no broken properties.

Fair pricing

We're aiming for a free plan and a one-time option instead of a monthly bill. Waitlist members help decide.

Why we're building it

It comes from the maker of a Notion Trading Journal that thousands of traders use. The most common request from those users is the same: "make the formulas just work." An app can do that.

FAQ

Is it available now? No. This is a waitlist to see if traders want it. Nothing is for sale.
