Hey Product Hunt! 👋 I’m Daniel, the creator of GainBoard.

Early this year, I lost tens of thousands of dollars in a single week.

I was making every classic trading mistake in the book: ignoring Stop Losses, holding onto losers hoping for a miracle bounce, and getting greedy with winning trades until they reversed into painful liquidations.

Everyone tells you to journal your trades to fix your trading psychology. But I ignored it because doing it manually in Excel felt like a full-time chore. When that massive liquidation event wiped out a chunk of my capital, I finally hit my breaking point.

I searched everywhere for a modern trading journal, but the market felt broken:

• Free tools were essentially static scratchpads with no live prices.

• Automated tools were absurdly expensive ($50–$100/month) and completely ignored on-chain DEXs.

• Scaling into positions (multi-leg entries & partial exits) broke the math on almost every platform.

So, I built GainBoard: an automated, set-and-forget trading journal and portfolio tracker that handles the complex math and tracks your psychology for you.

Here is what’s under the hood:

🔌 Non-Custodial CEX & DEX Sync: We don’t just connect to Binance, Bybit, and OKX via read-only APIs. GainBoard natively syncs with on-chain perpetual DEXs like Hyperliquid and Aster — for DEXs, you just paste your public wallet address. Zero API keys, zero private keys, 100% read-only.
📊 Real-Time Multi-Asset Tracking: Live market data across Crypto, Forex, Commodities, and Stocks. Track your Total Equity, Unrealized PnL, Win Rate, and Profit Factor updated down to the second.
🧠 Multi-Leg Scaling & Real Math: Scale in and out of trades with true weighted average price (WAP) tracking and automatic fee deduction. No broken trade history.
🎯 AI Trading Coach & Mistake Audit: Tag your emotional triggers (FOMO, revenge trading, impatience). Our AI audits your trading log to pinpoint exactly which emotional setups are draining your account.
🧮 Live Risk & Position Size Calculator: Enter your risk percentage, and it instantly calculates your exact unit size, required margin, and R:R ratio before you click execute. (Bonus: this calculator is completely free to use on our landing page right now — no login required!)
💸 Fair, Trader-First Pricing: A generous free tier, with automated pro features starting at just a few bucks a month.
🎁 Exclusive Product Hunt Launch Deal (Valid this week only):
Use promo code PH50 at checkout to get an instant 50% OFF on any Annual plan (both Pro and Elite) — that means you pay for 6 months and get a full year of GainBoard!

I built this platform to stop traders from blowing up their accounts due to bad math and emotional spirals.
